I'd like to reach out to anyone still having issues with USB DACs on the 6 and 6 Pro

The 6 and 6 Pro still have a bug where they don't properly pass on original audio streams to connected DACs. Depending on the DAC, you'll hear screeching, no audio at all, or severely reduced audio quality due to resampling by the OS. Apps like UAPP and Tidal don't work properly because they can't directly access connected DACs (so true MQA playback is impossible)

If you are affected by this bug, please star and comment on the buganizer tickets here, here and here. It would be worth our while to use the Send Feedback option within settings, and/or contact support to raise a ticket and submit bug reports (I realize this does take some time investment)

Hopefully I'm not the only crazy one using a DAC with a P6 screaming out into the ether. Help :cry:

yeah - something weird is going on. I love this phone so much. my Hidisz Sonata USBC DAC is completely hit or miss, sometimes it works, other times it won't. And the BTR5 can't play LDAC at full Audio quality only Adaptive - but both devices work on the 3 XL no problem, since day one. really weird.

That's weird, do you mean DAC connected via usb? I ask because my BT DAC is working great via LDAC codec.

Guess I was one of the first guys to report this issue. December update did not fix it. Google removed the headphone jack and forces people to use DACs and Dongles, but they did not do any test to ensure all STANDARD products are working correctly. You can use those DACs with 100$ phones and get better audio than with a pixel 6 or 6 pro. It's a joke and impedance from Google and definitely the last phone I bought.
And just to mention, I have some experience with android audio. I was working with the guys from sauron audio port and did a lot of other stuff. The DAC which seem to work are just playing with native/android software processed sampling rates. This is ****ty low quality. Any app, which tries to connect directly to the external DAC to play high res and bypass Android audio processing crashes. So buy a 10 dollar DAC, as any more expensive better solution won't work or gives you same crappy audio.

I appreciated seeing your thread about this and I've quoted it while contacting support. Best we can do is star and comment on those issuetracker pages linked above, and in settings, Send Feedback and contact support to submit bug reports

It's frustrating because DACs work fine on literally every other Android or iOS device (my Note 3 from 2013 still has no issues with this)

Even more frustrating is that if you try to use a Bluetooth LDAC DAC, you can't force 990 kbps. That's a separate issue

there's a few things wrong here. #1 is regular $15 DACs in many cases don't work (let alone $100-$300 ones). #2 you can't force 990kbps most of the time (in the 3 Bluetooth DACs I've tried and many others also, it constantly studders). so there's a few things wrong here that need to be looked at and resolved by Google.

I haven't experienced any of the "major" issues - mainly connectivity related. But I'm expecting things to go south once I receive my A.Q. Dragonfly Cobalt DAC/AMP. I have some nice Bluetooth phones that sound very nice, buy nowhere near the sound quality I receive through my LG G-7.

The G-7 has a pair of ESS DACs, and a more powerful amp setup. I found Qobuz's MQA files and the Tidal Masters that sound phenomenal. Especially ultra-high quality remasters of late 80's-90's albums.

The V-60 had a similar setup, but I traded that in for the P6 Pro, 256GB model. Qobuz and Tidal let you download MQA files while your subscription is active.

I was hoping against hope that someone has a P6/Pro with the same DAC to learn of the their experiences so far.🤔🤔

I reached out to the developers of USB Audio Player Pro as it has been removed from the Play Store for the 6 and 6 Pro. Here is their reply:

"Dear Robert,

True. The Pixel 6 and Pixel 6 Pro have a kernel bug that prevents third party USB audio driver from working, that's why we excluded it from the Play Store. We reported the issue to Google but we do not know when or whether they will fix it. You can track it here:

https://issuetracker.google.com/issues/210687963

We have verified all other apps that utilize their own USB audio driver and they do not work either, or fallback to the low quality Android driver. You can write that all apps that use the USB host API to play audio to a USB DAC do not work on the Pixel 6, including USB Audio Player PRO, Tidal, Neutron, Hiby, etc.

You can install this apk if you really want to run the app:

https://www.audio-evolution.com/priv_downloads/USBAudioPlayerPRO_6032c_pixel6.apk

Then you can turn off 'Use USB DAC' in the app's USB audio tweaks if you want to use the Android USB audio driver."

My Hidizs DAC works fine on the November .036 OS. About to reboot with January and expect it to work :) so I hope....

Havent tried my older DragonFly. Now just wish USB Audio Player Pro gets updated for the 6....
You would have a special Pixel 6, if your DAC really works in bit perfect mode... Like tidal MQA, USB Audio Player Pro and others.
I would state, it's impossible. Neither November, December or January Update fixes this issue.

You are playing low quality resampled music. Most DACs are capable of way more.

    Tried that DAC; all audio gets resampled to 48 kHz I believe (so no direct access/true MQA playback). Patiently waiting to see if the January update fixes this
