  1. Vivo NEX 3s Android 10 Specifications to its hi-fi DAC: https://www.akm.com/content/dam/documents/products/audio/audio-dac/ak4377aecb/ak4377aecb-en-datasheet.pdf Currently hi-res output routes the audio to the Snapdragon DAC / audio codec (Qualcomm Aqstic)
  2. I believe so too. Hi-Res used to work just fine with the hi-fi DAC on my Vivo X21a until a few months ago after a system update
  3. Without a 3rd party EQ app the MusicFX option in "Advanced Tweaks" will simply be greyed out and tells you "not supported by ROM". Having a 3rd party EQ app will force MusicFX to be available and serves as the system EQ. However, as you may have noticed from my posts, right now Vivo's Hi-Fi DAC does not like PA's Hi-Res output.
  4. Oh, totally forget this thread existed until now Vivo Nex 3s, Android 10 Hi-Res output technically works, 16 bit all the way up to 384 khz, but (as I have posted in the other threads) not through the dedicated hi-fi DAC
  5. 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.
  6. 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
  7. 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.
  8. 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.
  9. you're saying Vivo's supposed "hi-fi" DAC only output at 44.1k/16bit? could you please clarify a bit more?
  10. is there a definitive guide for the dither methods? like, why are they labeled as "fast" and "slow"? what is the difference between them?
  11. Tried that. Nothing. The phone runs Android 10 out of the box, and Poweramp is a fresh install
  12. @andrewilley Yes I have tried switching DVC on and off, no luck. I think the issue is Android 10 itself. My previous device is a Vivo X21a running Android 9 and there's no problem.
  13. @maxmp Yes I have posted in that thread as well I think the problem is due to Android 10 itself, since my previous device was a Vivo X21a which runs Android 9 and has no issues with the hi-res output
  14. 1. Devoice model: Vivo Nex 3s 5G 2. ROM: Android 10 stock, Snapdragon 865
  15. Yeah, tried fumbling around with previous builds, no luck My phone is Vivo Nex 3S 5G, running Android 10 stock. It has a hi-fi DAC which is not compatible with the high-res output. For builds prior to 860, selecting high-res output will activate the DAC but unable to play anything. The current build 877 does not activate the hi-fi DAC at all if hi-res output is selected. However, both OpenSL and AudioTrack outputs can activate the DAC and play without issue. Unfortunately both outputs locks the sample rate at 48 kHz which is less than ideal.
  16. Poweramp build 877 My phone is Vivo Nex 3S 5G, running Android 10 stock. It has a hi-fi DAC which is not compatible with the high-res output. For builds prior to 860, selecting high-res output will activate the DAC but unable to play. The current build does not activate the hi-fi DAC at all if hi-res output is selected. However, both OpenSL and AudioTrack outputs can activate the DAC and play without issue. Unfortunately both outputs locks the sample rate at 48 kHz which is less than ideal.
  17. Hi-Res Output extremely buggy with my phone's hi-fi DAC. only 16bit and sample rate defaults to 48 kHz upon launch unless I manually change it. Vivo NEX 3S 5G
  18. interesting, I got the DAC to work again after enabling "Emulate Media Stream"
  19. the current build is not compatible with my phone's hi-fi DAC when using Hi-Res Output Vivo X21A
  20. hi-res aux output works again for me, nice
  21. hopefully in the next update I'll be able to use hi-res output again
  22. Vivo X21a Android 8.1 stock Beta 790 CAN use hi-res output for wired headset/aux Beta 792 & 793 CANNOT
  23. unfortunately the Vivo X21 doesn't seem to give me the option to change the settings of the display color in any way. in any case here's what I was talking about
  24. when I used PA on my previous phone (Samsung Galaxy S7), there was no noticeable change in album art when I enable 24-bit RGB. on my new phone (Vivo X21A), with 24-bit RGB enabled, album art gets unnaturally darker and more saturated. is this due to my phones having different specs or an actual bug?
  25. 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.
