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 build.prop audio_policy.conf Link to comment Share on other sites More sharing options...
Fitzian Posted March 6, 2019 Share Posted March 6, 2019 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. build.prop audio_policy.conf Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
010 Posted March 19, 2019 Share Posted March 19, 2019 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??

Starfly Posted March 24, 2019 Share Posted March 24, 2019 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! Link to comment Share on other sites More sharing options...

It does vary by device I believe, but yes in most cases the output stage will be operating at 48K, even if your source material is being presented at 44.1. So might as well let PA do its work at 48K too. Andre Link to comment Share on other sites More sharing options...

Will Google a bit to see what I can find about the output stage of this phone. If indeed it's limited to 48K, then it's kind of pointless to run it at 96khz I suppose as at some point farther in the audio chain it gets downsamples again to 48khz (if I understand it correctly anyway).

Another useful info. According to the findings from the post below, it's better to turn off bit/banwidth mode and to use only bit mode or to turn the UHQ completely https://www.head-fi.org/threads/analyzing-samsung-uhq-upscaler-with-measurements-on-galaxy-note-8-exynos.873550/ Link to comment Share on other sites More sharing options...
