TRX40 chipset sound question

Recommended Posts

Posted · Original PosterOP

Quick question:  Does any of the TRX40 motherboards support a virtual sound input like stereomix, What U hear, etc.  i have a aorus master trx40 mobo  and i cant get  any kinda virtual sound input to appear.  hidden and disabled devices are not hidden in the recording sound device menu  and trying new or old driver dont make it work.

 

i suspect since trx40 run sound off USB  that none of them have this option.  please correct me if im wrong though.  if you have a trx40 based mobo can you please check your recording devices and see if you have a virtual sound input.  i need this information to either return this board for another brand or get a sound card.

 

Thanks!

owner of a TRX40 Aorus Pro Wifi here: the audio controller is over USB on this board too (windows also makes this very clear in volume control)

 

still trying to figure out system loopback input (although OBS handles this on its own). Stereo Mix isn't appearing on my end too

ive heard there all usb due to this chipset not natively supporting audio.  that confirms that gigabyte boards don't have a virtual sound input  i did try some third party programs.  it works but audio is disabled wile using third party drivers.  i wonder if msi, asus, or asrock has this issue too.

i looked this up, and turns out anandtech did cover this o_o

Anandtech:

All of the twelve TRX40 models at launch include a Realtek ALC1220 HD audio codec (S1220 for ASUS models), but the vast majority of the twelve also include a Realtek ALC4050H codec. We thought this was odd, so reached out to all of the vendors to find out what was going on. Turns out something really interesting.

 

It turns out that AMD did not include any onboard passthough audio in the chipet. That means that all the motherboard vendors that are using a Realtek HD audio codec for the rear audio have had to include the ALC4050H audio codec to bridge the USB to the I2S. The Realtek ALC4050H is used to integrate a bridge between the chipset and USB 2.0 to give the Realtek ALC1220 all the necessary connectivity to the onboard audio. Most of the boards in the stack use the ALC4050H codec to power the 3.5 mm microphone input on the rear panel, as well as the front panel audio as not to waste its capability.

 

Naturally, we asked AMD about this. The official response from AMD reads

The TRX40 platform does not support the HD audio interface used on most desktop and mobile processors. 

This means that it is down to the vendors to implement a USB audio device (Realtek ALC4050H) to enable use with the HD audio codecs on TRX40 models.

oof, i think getting a sound card might be in my future (have to check if it enables loopback input on the device)

 

EDIT: alternatively, see if your intended use is able to use the Windows WASAPI virtual device to grab the raw digital system audio output

i will try that.  but  it might just come down to getting a sound card.  man i haven't used a sound card in 5 years lol.  the sound blaster z by creative is a good choice if you are going to get one btw.

 

i kinda wish some one with a different brand trx40 mobo would reply so i can confirm my suspicions  and not have to return this and find out otherwise lol.

 

thank you for the help so far!

Bump.

I could really use any ones help  that has a trx40 motherboard other than gigabyte brand to confirm if other trx40 boards have stereomix or not.
