    Requests for Hi-Res Support (please state which build of Poweramp you are using)

    Vivo X21A

    Android 9

    Hi-Res output used to be compatible with the built-in DAC as recent as build 871
     

    Vivo Nex 3s

    Android 10

    Hi-Res output sample format only 16 bits available where X21A can do 24 bits, not compatible with DAC

    My Nex 3s uses the AK4377A DAC which is very capable

    The DAC work with OpenSL or AudioTrack. However both of those output lock the sample rate at 48k which downsamples my hi-res tracks.

    So far I've found 2 ways to engage the DAC without downsampling

    1. Get a 3rd party equalizer app and enable MusicFX. (I don't need to have equalizer app running). Even then the DAC will not start on its own, I need to go into AudioTrack output first to engage it and then switch it to Hi-Res output. As soon as I exit Poweramp the DAC unloads and I have to repeat the procedure the next time I launch Poweramp. Also any slight ducking in audio will unload the DAC

    2. Use Neutron Player

     

    I am just reporting the behaviors I've observed so far, not sure if any of that actually contributes to anything.

    Please understand that this operates (the same on each android device) built-in system 5 band equalizer + other built-in effects, but it indeed has the activity for MusicFX intent. The effects usually don't work with hi-res and force resampling. Though, this is offtopic.

    Yes I am aware. Noozxoide is never opened or running. I'm just saying that simply having a 3rd party equalizer app is enough to get the DAC to work with hi-res output.

    1. Devoice model: Vivo Nex 3s 5G

    2. ROM: Android 10 stock, Snapdragon 865

    Messed around a bit more and found an interesting behavior.

    Back when first installing Poweramp on my new phone I noticed the option to turn on MusicFX was greyed out, now thinking back I believe it's due to the system audio effects keeping out 3rd party apps. So I ended up downloading Noozxoide EIZO-rewire. The MusicFX option became available which suggest that Noozxoide had served as a stand-in for system audio effects. And somehow by doing this the hi-res output is now able to engage my phone's DAC.

    Still not a perfect workaround, however. The resolution is stuck at 16bit and sample rate defaults to 48k everytime Poweramp is launched and I have to manually select higher sample rates.

    Are you sure? 790 doesn't do any further checking on the output stages, so while it may be processing high-res internally in PA, you could find your device is converting it back down to 16-bit/low res.

    709 does more checks and shouldn't show the option unless HD can be achieved along the whole audio path.

    I'm not familiar with the more technical details but my experience with PA on the Vivo X21 has been:

    705--Wired Headset/AUX available for OpenSL ES HD but music will not play if I enable it

    709--Wired Headset/AUX is not listed for OpenSL ES HD

    790--Wired Headset/AUX available for OpenSL ES HD and music plays when it's enabled

     

    If this helps, the phone has a Hi-Fi DAC, in the settings I have Hi-Fi mode enabled for PA. When music is playing through aux in PA 790 the Hi-Fi notification shows up indicating it's active.
