It could be that they are just linking 1080p version, regardless of the quality setting. I'm not sure, but from downloading videos I assume they don't have active encoding, but load the video based on selected resolution. And since the point of the site is to test features, not video quality, it would make sense to not stress servers more than its needed to test features.

I had the exact same issue with my M2. I found that when I plugged it in using a PCIe USB 3.0 card it worked perfectly.. till it crashed my USB controller and eventually lead to a frozen Windows session.
The hardware on the Motu M2 is probably the best for any budget interface but the (Windows) software/ drivers suck ass. The drivers are just terrible. When using on my Mac it worked so well that I was tempted to keep it anyway but eventually ended up returning it. I refuse to use hardware with such faulty drivers.
If you are a Windows user and can return it, I would strongly advise that you do so and get yourself an interface with proper drivers. The G3 Scarletts are pretty stable, IMO. You can even try Audient ID4 or something.

lol are we at this again? For the record Linus didn't claim that he doesn't pirate stuff. He just said that it affects the creator and we need to be aware of the impact. The solution now is just to get Linus' attention so reimbursement or something can be made. I'm guessing most likely Linus wouldn't notice these kinds of minor stuff.

I'm painfully aware, though I would maybe say "distant memory" rather than dream. I've got schematics for most (not all, but most) equipment right up until about 1995. After that it starts getting pretty sparse. 
 
 

you check benchmarks for the games you like to play on 3060/3060 Ti and the 3070.

60FPS high to medium settings i believe is doable in 3060 Ti @1440p but that is cutting it close and no headroom for higher quality games. so I believe the 3070 or higher is the right card for 1440p but anyway checking YouTube for benchmarks is the best thing to do to be sure you get what you expect.

since you will game. what is the resolution you will game at?

3060/3060 Ti will be good for 1080p but if you are trying to max settings + high fps on 1440p you wont be able to do that. so 3070+ is the right card for that

and from the prices in my country the 3070 same price as 3070 Ti 😄 so no one buy normal 3070 anymore

The xduoo xd05 basic is pretty great at this price point should have enough power to drive a 250 ohm 990. the ifi idsd bl nano is also a good option @$200

Generally speaking, the headphone amps in an audio interface could be described as "acceptable", but that's about as nice to them as I'll be. It's well-known that the Scarlett in particular has a rather mediocre headphone amp. Being realistic, it's amazing that they can get as much into those boxes for $150 as they can.
 
The M2 is almost certainly the best interface in its price range. Some of us over at DiyAudio did some measurements on the M2, and the line inputs / line outputs have extremely low noise and distortion. It's a good candidate for use as a measurement tool (within its limitations, that is). 

ASR did some measurements on the headphone amp as well. Distortion looks good, but it's rather limited in power. 22mW into 300 ohms isn't great, especially when we consider having dynamic headroom. I do find it interesting that it delivers about the same amount of power into 33 ohms as into 300 ohms. That's a little unusual.
 
Now that said, this is pathetic compared to even something like the O2 headphone amplifier, which is very easy to outperform these days, especially now that the OPA1656 has been released (which is a bit of a game changer in the audio op-amp world). I've been meaning to design a headphone amp around the OPA1656, but I don't use headphones very often these days so my motivation hasn't been there. 
 
So IMO, the M2 is a fantastic DAC / ADC for the price, but if you already own a good DAC, know that in buying the M2 you're probably buying about a $2 headphone amplifier, but that's still a big step above what's built into a computer motherboard (which is probably like a $0.80 headphone amp at best). 
 
Also, the mic preamps in the M2 are fine. They aren't bad, but it's not like they're a Neve / Focusrite ISA / API. Good enough for podcasting though.
 
 
 

Your software volume controls need to be at 100% to avoid reduction in bit-depth
Just turn down the hardware volume controls to compensate.

just update for the sake of documentation if someone wondered how the Motu M2 sound with Byerdynamic DT 990 Pro 250ohm

Its amazing.
focusrite 2i2 2nd gen wasn't even close to what i hear now.
focusrite solo
and soon will test fiio k5 or k3 to use as portable DAC with phone.

1- the amplification is loud enough and there is plenty of headroom. (my pc is on 70%, volume nob on Motu is 70% and the itunes is 60% , VLC 55%)
if i put everything 100% i cant put it on my head literally so loud that i take it instantly off.
songs tested:
main-title-legends-of-azeroth  (world of warcraft)
The benchmark Song - Single (Elric phares)
Zweihänder - Ear Slayer - 01 Video Games (logan tek syndicate guy)
tested all of them from itunes,and vlc

2- the onboard audio cant even compare. so the Motu m2 screen very clear and bright enough to the point its easily visible but not annoying in Dark room well balanced.

3- the focusrite was bad in comparison in the lows somehow it wasnt giving me flat EQ.
the Sound blaster from creative was booming everything which annoyed me because i listened to those songs many times in many devices and i know how they should sound but using my headphones to the sound blaster was like using gaming headsets all over again 😞 

4- I still didnt buy a mic yet am not sure if I used a hard to drive mic will effect how much it can power the headphones or will there be any electric noise leak etc.. will update soon once I get a mic ,am thinking to buy Rode podmic.
 

well for now I can use my front audio jack of the case they can give me enough sound , they advertise that front is amplified like the back io on my mobo.
this noise thing is weird , my pc is maybe 3 years old but i swapped the psu i had electrical problems in my room everything break so i bought a ups to solve it and swapped the dead psu.

my current psu is bad and make more noise than previous one but it make my pc run XD am planning to upgrade entire pc soon and  will only keep the case+ram+ssd
will get a seperate server machine and upgrade my gaming pc.(upgrade the ups)

so yeah will have to buy lots of stuff coming soon.

but for now , I decided to use the headphones on my pc like this and on my mac(sounds fine) till Motu M2 in stock. I think we can mark it as solved in 1-2 days if no one suggested something else

Personally I find reliable stat's hard to come by and difficult to understand when I find them so I just go to audio related places and ask for advice.  The follow up to that being I just have high power amplifiers so I'm not limited by technical restraint's any more.
 
How old is your PC?  I'm asking only because I had an issue with audio noise, like a really bad noise floor after I swapped power supplies, the old one had no problems then the new one was noisy af even though it was just usb to a dac.  I ended up going with a very expensive galvanic seperation (no physical connection) to get rid of the noise but after a few months when I went back to a usb link........ no noise.  So I'm thinking that some psu's might be noisy when new.  But this is a very uneducated assumption based off limited anecdotal evidence.  But I've seen even a seasoned head-fi youtuber brought to befuddlement by this issue, Joshua Valour.
 
I would normally agree that a usb dac situation should do the trick but in my case even the usb was noisey.  But as @rice guru said it's only $10 and it's the go to cheap usb dac.  I will just add that powering a pair of can's vs properly powering them are not the same thing (still learning what that means myself)

if you need something now hat should help this issue. the apple usb c dongle dac can power it to a pretty respectable volume level. testing it now it gets fairly loud.  only $10 and should be much cleaner than your onboard audio its a good $10 fix to hold you over until you get your new interface. 

Ohm is not the only one you should worry about, the spl nominance plays a factor too.
My DT880 and DT770 are both 250ohm and they are harder to drive. My Amiron Home is 250ohm too and it's much easier to drive and the measurement is a simple Samsung MP3 player to test their efficiency. Amiron Home has sensitivy of 102dB while the DT's 96dB or something.

Basically anything will pair well with a 600 o headphone in regards to output impedance as the output impedance should be ideally below 60 ohms which is rare ish in modern gear for it to be even above 1 ohm

Output impedance and input impedance a different relationship and is not really about power output on the amp.

The reason I dont comment on posts about what headphones sound good etc is because that is subjective to people. I only every do it when I have specific personal experience with that headphone. 

But when the question is does this headphone work on this amp. That is just maths and results in a yes or no answer. Some amps do change the sound, but I never comment on that because its subjective and most lower end amps and computer amps have little sound difference. They are all have a good flat amplification

If your comment was asgard sounds better the the modi. I wouldnt question it, thats subjective to peoples hearing. Thats a perfectly acceptable opinion.
But if you said you need the asgard because of the extra power. I will calculate the power requirements and comment.

So when people say YOU NEED A AMP for this headphone, I calculate the power requirements to get to a suitable volume and since most computer audio doesnt have specification I have to presume some things so most comments I say should or probably but there is a stage that computer company's even though they dont spend big money on the audio components they dont spend no money and on board audio in computers etc is reasonably good.

The thing is most headphone company dont sell a product which cant be used without external amps and dac. Unless your buying stupidly high end headphones amps are not normally needed.

I'm going to have to counter this.
 
Yes, in theory, everything is measurable. But do we have the equipment to measure and interpret everything? No.
Frequency response is not the only measurement that is important. There is a csd/waterfall plot, impulse response, and much more, and that still doesn't fully describe the sound.
Yes everything is measurable, but everything isn't measured.

You need to apply experience more than theory.
 
There is a difference between possible and best practice.
 
You may not have the ears to differentiate or the funds to experience, but don't take your theory as a replacement for experience.
 
I don't have golden ears by any means but I can tell you that there is body behind properly powering a pair of headphones.
 
I had to put you on my ignore list, as the first person there, because you said that a 1990 doesn't BENEFIT from anything beyond onboard.
 
Can you play it onboard? I don't know probably, but to make a statement bold enough that it will NOT benefit..........  Yeah I don't need to hear anything else you have to say.

OP I can't confirm whether or not the M2 can power 600ohm Beyers but I can confirm it powers 250ohm Beyers fairly easily, when it comes to amplification of course there is a difference between the numbers and what is seen in actuality, low quality amplification chips can cause interference or otherwise disrupt the signal though numbers might suggest it would work perfectly fine. And that's assuming they report the correct figures for their amplification chips which isn't a given.
 
Sorry I can't provide you an answer but absolutely quality of amplification matters.

Christ already answered this but ill throw maths at it this time.

If at 55ohms the M2 produce 190mW you can calculate 600ohms using maths. Can I be arsed to do the maths. No. Is there websites which did it for you. Yes.
https://www.rapidtables.com/calc/electric/watt-volt-amp-calculator.html
Step 1 add in the data you know. So 55 ohms and 190 mili wats and calculate. Now you have the current and voltage and can now change the resitence to work out the power
Step 2 delete the 55 ohms and replace it with 600, delete the power and calculate again

You end up with at 600 ohms the M2 can produce 17 miliwats. 

Now you can use that data and headphone data to work out how loud it will be. Sadly beyerdyanmic havnt given the snesitivty of the headphones. But its okay because google.
95.43dB per mW

Now we use maths again. Ahhh I cant be arsed to the website.
https://www.hear.reviews/2019/06/01/headphone-power-calculator/

Lets type our data in. do do do calculate.
The answer is 107dB is the max SPL the M2 can run the DT990 600 ohms at.

Lets see comparable loudness graph

107dB on the chart is similar to being at the front of a loud concert and required ear plugs to prevent hearing damage.


So the simple answer is YES they can run them up the a volume that will cause hearing damage

Ok so this is getting more attention and I'm dealing with a few customers with the issue so I'd like to get some proper info to take to a rep at nvidia if needed.
So lets stack the info.

Just replaced my Corsair AX850 Titanium (bought for this new lovely gpu - MSI Ventus 3X 10G OC) with a beQuiet Straight Power 11 1200W Platinum.
 
Positive:
- far less coil whine
- 3D Mark got me some points (12 928) ( https://www.3dmark.com/3dm/50743594?
- 3D Mark stress test was fine (98.6%) https://www.3dmark.com/3dm/50746602?
- temps are good (71 °C)
 
Sadly the negative points are still the same... almost any game I try to launch dies (CTD) within the first 1-2min at it's best (e.g. Borderlands3, Warzone crash right after loading screen).

As stated before I can only hope that a new driver can fix this. The benchmarks just seem too good for a defect chip - at least I guess so.
 
Slowly you can find more and more voices / threads about 3080s not running any games - https://wccftech.com/nvidia-geforce-rtx-3080-users-report-crashes-black-screens-during-gaming/ (the last summary I found)
 
If anybody has suggestions or questions feel free to ask, I will provide whatever info I can.

PS: Without any fixes for the next week or so I will have to return it to my reseller. Not paying 700€+ for non functioning hardware.

This is a relative new problem, I found some info and half is chinese.
