@kirill_zverev check if audio.offload.disable=1 is set in your build.props (or via adb shell getprop), if so, hi-res output is explicitly disabled by Meizu for your device as well (as they did it for Meizu 16).

I've just installed new version of firmware (FlyMe 7.2.0.0A, Android 8.1.0) and there is no "audio.offload.disable" line in buildprop. Poweramp still doesn't see higher that 48 khz

1. FiiO X5 3rd Generation

2. Android 5.1.1 , Custom Rom (Fidelizer) Based off of Firmware v1.2.2

3. See file format support listed here and attached audio policy. Stock music app, USB Audio Player Pro, and Neutron all support its hi res playback.

When headphone cable is connected to player's unbalanced 3.5mm headphone output, output switches over to "Wired Headset/AUX" but is only active at 16bit/192kHz. When line out cable is connected to player's 3.5mm line out, output switches over to "Speaker" and reverts to OpenSL ES at 16bit/48kHz. When headphone cable is connected to player's 2.5mm balanced headphone output, it remains same as "Speaker" and uses OpenSL ES at 16bit/48kHz. Very odd! Using build 820.

1.Xiaomi 6

 

2.Android9.0(pixel experience unofficial)

 

3.Qualcomm Snapdragon 835

 

Hires can work on official rom(MIUI9 with Android 8),but can't work on Android 9 (No sounds after open hires output ) Hope to solve it. The serious background noise on Xiaomi 6 without Hires supported.

Samsung Galaxy Note 9 SM-N960F

Android 9 firmware N960FXXU2CRLT

Hi-res worked before the last Android 9 update. When I try to use the output the error message pops up and Open SL ES is used

Can somebody shed some light about the problem with Hi-Res output and DVC on Samsung devices with Android Pie?

 

For details see the following links or search in these forums. High-Resolution-Audio-Support has been generally declared an experimental feature. Especially Samsung with Pie seems to be a problematic platform.

1.  HTC U Ultra

2.  Android 8.0.0 (Stock rom)

3.  The option of Hi-Res output for USB DAC - Sonata HD Audio is limited to maximun 24bit/96kHz (but the device is support up to 24bit/192kHz) and HTC U Ultra can also play the format FLAC 24bit/192kHz (tested)

 

but the sampling rate are limited by Poweramp, USB DAC Sonata HD Audio should be support up to PCM 24bit/192kHz with Cirrus Logic CS42L42 chips

will it release the restriction for support 24bit/192kHz output options??

The S7 Edge SM-G935FD doesn't support Hi-Res ? Strange. My S7 SM-G930F does.

I'm using a Samsung Galaxy S10 (US version with SD855 chipset), and when playing back Hi-Res FLAC I can change the sample rate (ie 96khz) but not the sample format, it's stuck at 16-bit. I'm pretty sure the S10 supports at least 96khz/24-bit.

Also, perhaps more of a feature request, is there a way to just always use the sample rate of the source file? Now whenever a sample rate is picked every file plays at that rate, which often means that a 44.1khz file is upsampled, requiring more processing power and draining the battery more quickly. It's my understanding that this is deliberate on your part as it can cause issues with gapless playback and buffering when switching between two files with different sample rates. I'd however ask you to reconsider and at least provide it as an option while warning users of some of the downsides (gapless playback typically only matters between files on the same album and those will usually have the same sample and bit rate anyway). 

The build I'm using is 823-play (full version). 

Thanks!

Sorry, just saw that you haven't got that option.
