Lien028 Posted November 15, 2020 Share Posted November 15, 2020 Hello everyone. I've purchased Poweramp awhile back and have used it with no issues on my Galaxy S9 along with my Tempotec Sonata HD Pro DAC capable of 384kHz/32bit output. On the S9 it would default to 192khz/24bit output with the Audiotrack output selected in the audio settings. I've purchased a new phone (Xiaomi Poco X3) running MIUI 12.0.2 Android Q. Upon installing Poweramp (v3, b884), the output of the USB DAC is limited to 48kHz/16bit on both OpenSL and Audiotrack. I could alter the sampling rate by enabling Hi-res output, but that introduces a lot of latency. On the S9 with Audiotrack output selected, the sampling rate was 192kHz with low latency of around 80ms compared to the Xiaomi hi-res output having 200ms with 96kHz selected. My questions are: 1) What could be causing this issue? My guess is the stock player interferes with Poweramp's direct access to USB audio. 2) Is there a difference in altering the sampling rate on Hi-res output vs allowing the native sampling rate of the device (192kHz/24bit) to be utilized when Audiotrack output is used? Thanks and hope you could help me out. Attached are screenshots of the issue in question. https://i.imgur.com/ctVfnEn.jpg Quote Link to comment Share on other sites More sharing options...
