  1. 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
  2. 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.
  3. 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
  4. 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.
  5. 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
  6. 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.
  7. 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.
  8. you're saying Vivo's supposed "hi-fi" DAC only output at 44.1k/16bit? could you please clarify a bit more?
  9. is there a definitive guide for the dither methods? like, why are they labeled as "fast" and "slow"? what is the difference between them?
  10. Tried that. Nothing. The phone runs Android 10 out of the box, and Poweramp is a fresh install
  11. @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.
  12. @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
  13. 1. Devoice model: Vivo Nex 3s 5G 2. ROM: Android 10 stock, Snapdragon 865
  14. 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.
