HDMI Audio not working

[kiki4431]

Hello

 

I am trying to connect a home theater system to my TV and computer.

 

at this moment everything works, I have a Onkyo HT S3800 5.1 Home Theater System connected with an UHD TV Grundig 49 GUB 8960 on standard DVBT-2 terrestrial TV the sound goes to AV via HDMI ARC.

the computer is connected via HDMI to AV reciever.

At this moment the computer specs are:

CPU: AMD Ryzen 3400g (OC @ 4.1 GHz stable); GPU: (OC @ 1.7 GHz);; VRAM: 2 GB (stable)

MB: MSI B450 Tomahawk

RAM: Corsair RGB PRO 16 GB (XMP enabled, with some latency tweaking (stable))

SSD: Samsung 970 PRO 512 GB

monitor: Acer SA220QAb (connected to MB DVI connector via HDMI 1.4 cable and HDMI-DVI adapter)

the Onkyo AV reciever is connected to MB HDMI connector via HDMI 1.4 cable

the Grunding TV is connected to Onkyo AV reciever via HDMI 1.4 cable with ARC enabled

 

Now this is where strange things happen...

I decided to add a discrete GPU to my system, I chosen Gigabyte Aorus RX 560 (https://www.gigabyte.com/Graphics-Card/GV-RX560OC-4GD-rev-20#kf this one not the one with two fans- I found it for a great deal and I couldn't afford a better one) Anyway this is the only change I make.

so with all previous mentioned specs just add that GPU running on stock.

all drivers are up to date.

 

as soon as I connect everything, my TV to HDMI connector and monitor to DVI connector using the adapter, just like before, I can't get sound on my TV or Onkyo AV reciever, I tried connecting just the TV bypassing the Home theater system, but still, there is no device to output sound to apart from my speaker connected to my computer.

Video is working though

I tried connecting to different HDMI In ports on both my TV and AV reciever, but my computer just doesnt see speakers connected to HDMI on my GPU, when I go to troubleshoot, it does see HDMI Audio on my GPU but it says that there are no speakers connected to that port.

Than I tried updating drivers - not working

Uninstall drivers completelly, leaving just basic graphics driver from Microsoft - not working (in fact I can't even get video to my TV if I do that)

Reinstall again performing a Factory Reset, used older WHQL version from AMD - not working

Now I disconnected my monitor and leave just the TV pluged in - not working

I thought there is a conflict between my iGPU and new descrete GPU, so I disabled iGPU in BIOS and allocate 64 MB (minimum) of RAM to the iGPU)

Tried everything again - not working

Reenabled iGPU again set allocated memory size back to 2 GB

disconnected my monitor again and leave just the TV pluged in - not working

connected the monitor back to MB DVI port - video working but no audio again

connected TV back to MB HDMI port - now something new happens - all I get on my TV is a completelly green screen, nothing else just a dark green screen.

took the Graphics card out return everything back as it was and brought the card to service center to test for audio, since apart from that TV I cant test it elsewhere.

They did plug it to the TV - not sure if it was exactlly the same - i think not, or that they had exactlly the same PC but as they say it did have the iGPU, again not sure which one because they didn't say, what they did say is that Audio is working fine.

but if everything is fine why can't I get audio...

I think maybe the cables, they are all 1.4 and the TV is 4k HDR so the cables might be causing this...

Anyway I ordered 3 pcs 3m long HDMI 2.0 cables with 1 pcs HDMI repeater because the computer is in another room and I need at least 6 m cable lenght and 2.0 is strugling on 5 m long, the third cable will go to my reciever from the TV for ARC feature.

 

My question is: will this help, I mean I think the cables are to blame but am I correct? if not I still need 2.0 cables to make HDR working.

And why else can't I get sound out of my GPU?

 

Thanks in advance

Best Regards

Did you change your default sound device to the new video card in the sound settings?

as said here, I did, however I get only Realtek speaker, which is my MB sound controller, to which my main computer speakers are connected to, and Steam streaming speakers, which Don't give sound anywhere, I think those are some sort of virtual speakers, I don't know. when I go to troubleshoot, than it asks me which device I want to troubleshoot, and appart from the two I mentioned I get two AMD High definition Audio Device HDMI - those are HDMI, but when I click that, it would say that no speaker is connected to that port.

yesh....if theres amd device showing but no speaker it has to be the hdmi cable. when connected to a avr. windows will detect that its an avr. same as tv. audio, so theres a lack of compatibility or communication between your comp and device

Ok new cables have arrived, this is how I connected them.

So I used 3 cables 3m long each and a single HDMI 4k repeater.

I connected first cable to my PC and input port on the repeater, and secound cable to output port on repeater to TV, third cable goes from TV ARC to AVR.

At some point I actually got audio to work from my GPU (it did recognise the TV) but I had some resolution issues (The TV would have a scalled up blurry image, like my GPU is processing at 1080, and than my TV is upscaling that, while my monitor is getting 1080p, or vice versa, my GPU would be processing at 4k and than I would get a quarter of image on my main 1080p monitor - solved that by enabling VSR in Radeon settings, but than I lost audio, now if I disable it I still don't have audio)

Now I repeat all the things I done before plus, I installed and reinstalled speciffically the AMD High Definition Audio driver, and I still can't get sound to work, if I connect the cables to my MB/iGPU i get sound but no HDR since it's a 1.4 port, however the sound is stereo only can't switch to 5.1 because it is grayed out for some reason in sound settings, I guess my TV won't forward more than two channels of Audio through ARC, even though I can't see why, when I go to my TV settings I can activate surround sound, and there is a setting can't remember what it's called but options are "PCM" or "Passthrough" - whichever I choose won't do anything, under HDMI section, there is also something called HDMI EDID - options are: "default", "1.4", "2.0" - I set this to 2.0 - I guess this tells the TV what sort of signal te expect.
Also now when I connect the cable to my GPU, I can get HDR and all that but no sound -  I tried installing the driver from CD that came with the GPU to no avail, I also tried installing drivers from Windows Update, but nothing.

I really don't want to throw a good GPU away because of some stupid driver issue, and I can't afford new one, is there something I didn't try but could solve the problem?

thats arc for you.....arc is stupidly unreliable.....id go optical route with the audio if your receiver supports it.
now as for the other issue. it very well could be the 1.4 hdmi...it doesnt have the bandwidth hdmi 2.0 has....try this  set video to 4k 30htz 422 see if audio works or even 420
that repeater (not sure what one you have. might not be the best either. distance your a lot better off going the optical hdmi route when over 2m.

I have been thinking...

 

So my situation currentlly is that I get good audio but no HDR on my integrated GPU with 1.4 cable connected from my MB port to my AVR, and with 2.0 cable running from my discreete GPU to TV, I get 4k HDR, but no sound, so can I by any chance connect everything this way and have both sound and 4k HDR???

yesh im not sure honestly. ive never dealt with igpus with discrete. im thinking you have to choose one or the other thou

It works, I connected everything the way I desribed and had to disconnect my main monitor because it would conflict with lower resolution plus I have to use extend displays because windows see the AVR as a secound display, but I get both 4k HDR at 60 fps and 7.1 audio, however like you said I had to lower subsampling to 4:2:2 to get 10 bit color, or even 12 bit, othervise if I try to set 10 or 12 bit color and 4:4:4 I would get no signal on TV.

 

It's not over however, just as I celebrated the final victory so to speak against the tech problem, now I have another, I shuted down my PC for an hour untill I arranged the newlly set cables, and when I powered it back on, I got VGA light on my motherboard turned on, thought maybe I didn't seat my GPU right, so I reseat it, still red VGA light, I tried to disconnect all the devices but my main monitor, still red light, than I tried taking out my GPU and leave everything on my iGPU, red light is still on, even though at this point everything is exactlly as it was for the past 2 years since I built my PC. so I tried resetting CMOS, it didn't work, eventually after like 5 CMOS resets and 100 powercicles it boots up normally, and for curiosity sake I dicided to shut it down again and power it back up- yeah same issue again, 100 powercicles later, it boots fine, any ideas?, just writing this post after it started finally, I don't understand the cost of having a 4k HDR video with audio apart from hardware cost you also have to deal with a hundred issues and such...

considering you gpu has hdmi 1.4. and your trying to run 10bit. dude you need a newer card. hell hdmi 2.0 does max 4k 60htz 444 8bit, 30htz 444 10bit, 60htz 442 10bit and all with full audio....
amd 550, 560, 570, 580, 590, 5500
nvidea 1650, 1050ti, 

all under 200.

its now sounding like a gpu issue (maybe not) but newer will help

GIGABYTE RX560 4GB OC REV2.0 (https://www.gigabyte.com/Graphics-Card/GV-RX560OC-4GD-rev-20#kf) - this is the one I currentlly have in my PC as a discrete GPU - it does support 4k and it has 2.0b HDMI port. To that card's HDMI I connected my 4k TV, and to it's DVI I connect my 1080p main monitor by using DVI-HDMI adapter.

Now to my MB HDMI port which is 1.4 (1.4 does support 4k but max 30 Hz and 8 bit (no HDR)) is connected my AVR.

 

At the time this error occurs I disconnected my TV and my AVR, and tried running only my main monitor exactlly how I did untill now when everything worked, so that monitor is connected to my iGPU or my MB DVI port by using the adapter - also tried connecting to HDMI port dirrectlly, I put the GPU (RX560) out of the system and still get VGA light.

 

Now it's not a hardware issue, I forgot to mention I do get Video signal on my monitor despite the error, but it's just blank black screen (you know when you power up your PC before all the BIOS logo and information, there is a split secound just a black screen - you get signal but nothing shows up, and after half a seccond you get all the POST information and stuff or BIOS logo, deppanding on BIOS settings you make., on my PC it just kinda freezes in this state just before it needs to display that MSI gaming arsenal logo). If it were the hardware issue it wouldn't behave like that (at one time everything is fine, another it's not, than another again everything is fine), I would face a single error constantlly no matter how many times I powercicle it or reset the CMOS. maybe BIOS is making this error (ever since I built my PC sometimes I would get a CPU error, sometimes I had to reset my CMOS, sometimes just a powercicle will fix it, until a recent version of BIOS now I faced the issue only once and than I realized it is happening more often when I press and relase the power button, but if I hold the power button for like 3 secs, than the chances of CPU error seem to be verry small. - Doesn't work with my GPU however.

argh hmmmm wait rereading...default the cpu...dont overclock your saying stable now looking this over it actually may not be stable. even set ram to its default settings if have to
that 560 should be fine for both video and audio. (my daughter has that card) and it works fine at 4k settings

Well, if you are refering to CPU errors I gave as an example, that was happening before any overclocking.

 

Now, continuing from here, I went to check if my BIOS perhaps has a newer version, and it did, as said in the changelog they actually fixed the audio issue with RX 570 GPUs, so I flashed the new BIOS set back all settings frequencies, voltages etc., according to my OC., and I updated chipstet and audio drivers as well., and now, well it takes a little bit more time to boot, it does stay on VGA light for a few secounds (before it just blinked and then boot light blinked and than the windows would start), but for now it works, the GPU outputs audio and everything, however I can no longer run both iGPU and discrete card at the same time (I have to choose in the BIOS which one I want - just like you said I will have to), so my working connection between my AVR and HDMI port on my MB is no longer valid.

 

Now to multichannel problem I described earlier, as you said I should try optical cable, sure I bought 5 m toslink high quality cable at local electronics store, but when I connect my TV to the AVR, I can get sound but no mater what effect I use on my AVR, even my Dirrect sound (which is bassically my AVR sends whatever it gets dirrectlly to speakers (no additional processing)), all would have some kind of echo effect, kinda like ghosting efect on monitor but with sound, I couldn't correct that, plus when I connect my PC to my TV I still can't get more than stereo out of my TV (meaning my TV just won't pass any more than 2 channels of audio), I returned the cable today and order a DP to HDMI adapter, that GPU has DVI, HDMI and DP, and DP does also carry audio, my idea is that I get a DP to HDMI adapter connect my AVR via that 10m 1.4 cable I used all this time to the adapter and than to GPU, I leave my TV connected to HDMI connector as it is now, and I use DVI for my primary monitor as it is now, bassically instead of connecting my AVR to MB's HDMI port - since that no longer works, I connect it to my GPU DP via DP 1.3 to HDMI 2.0 adapter, everything else would remain the same. hope that works...

ok i think i had the same issue you did out of the blue yesterday (but i have a 590 and a 3600 no igpu), for no reason what so ever no sound would go to my avr. windows said stereo. but direct to tv there was sound. went through all the driver reinstalls and everything. fing gpu light at post.......i unplugged it, walked away. came back after calming down. plugged it in and the damn thing fired up with everything working. been working normal since...i now know your frustration.

[kiki4431]

Solved:

The HDMI to DP adapter has finally arrived, I connected everything the AVR to HDMI adapter connected to my DP on the GPU, TV connected to HDMI output, and now everything works, I can get up to 8 channels of audio and 4k HDR 12-bit video @ 60HZ and 4:2:2 subsampling.

 

I can't connect my primary monitor to DVI however, as soon as I do that the driver would crash, but that doesn't matter anyway, if I am watching a TV at that time.

 

there is only one issue that I can see, it's more an annoyace, I can live with that... , when watching 4k video sometimes at the botton of the screen on my TV there would be a white thin blinking line going from middle of the screen to right end of the screen, just at the very edge of the panel.

 

and of corse the effort to set everything up (every time when I want to whatch HDR content, I have to enable HDR in settings app (than dissable othervise the collors are washed out on SDR content), and set my driver up too, in radeon settings I need to apply 12 bit output for my TV, and 4:2:2 subsampling.

 

and I have to do all that through Team Viever, since I can't have my primary monitor connected at the same time.

 

So I have to either use Team Viewer or excercise walking for half an hour from one room to another to click on something that I need.

 

Well it works that's what matters.

Thank you all for help
