@RiedRied on recent Samsungs 3.5 output (or usb-to-3.5 dongle) bitwidth depends on sampling rate. This is only for wired connection, for example BT bitwiddth depends on codec, and usb dacs are another story. Thanks!

Thank you ! Good to know ! So if I don't want to lose precision - the DSP works with 32 bit it seems - I have to upsample to 384 kHz ( for Poweramp on recent Samsung hardware with wired headphones ).

Yes. However 32-bit audio depth is one of those pretty pointless numeric spec 'one-upmanship' games - and no phone actually processes to that level anyway. Even 24-bit audio provides a massive dynamic range of 144dB, which covers the range from complete silence to standing right next to a jet engine during take-off. 32-bit provides a ludicrous 192dB of range, exceeding even a rocket launch. So no domestic musical equipment will be reproducing sound to that level.

@RiedRied I believe 88kHz and 96kHz are accurate figures, so it's not 88.2kHz as a multiple from 44.1.

I tried it out with a test file with sampling rate of 88.2 kHz - Poweramp just displays that as 88 kHz. Which is a good thing actually (not the display, but the fact that it's 88.2) - nobody would need a slightly uneven multiple of 44.1 kHz 🙂 .

Thanks a lot ! That's an interesting link ! So for all practical purposes of music playing 24 bit should be more than enough, that means for Poweramp on Samsung upsampling to 192 kHz.

As you can see the file is mkv but Poweramp thinks it's mka for some reason. 

I've just checked it and you are right - even with the 'Ignore Video Files' option enabled, the PA scanner is still detecting MKV files and putting them in the library (marked as MKA, which is the audio element). It does correctly ignore MP4 files which contain video & audio elements though.

Another thing I noticed. It's about systemui volume controls menu on MIUI 12. I set my volume levels to 100 in Poweramp (system default is 16). When Poweramp is running and something is being played on it, the volume controls doesn't show up outside the app. But if I change volume levels settings in Poweramp back to system default, I can see systemui volume controls outside the app.

^^ Above screenshot is taken with volume levels set as system default in Poweramp. The controls simply doesn't show up outside Poweramp app if volume levels set as anything other than "system default". I mean I can hear that volume level is being changed when I am pushing volume+/- buttons but the controls menu doesn't show up. But if I pause Poweramp, everything returns to normal. I am guessing it is related "volume icon may look like remote media" warning. So far I haven't seen such icon on my volume controls menu. On my android 8.1 stock ROM, it does show up tho.
