How to prevent resampling to 48kHz by Android system?

Some devices are set by the manufacturers to force 48kHz output for their normal output, even for CD-quality audio (which is recorded at 44.1 kHz) . If so, you might like to try hi-res and change the output to 44.1, that might get around the issue for you.

Is that happening here?

@andrewilley Someone I know told me all androids resample to 48kHz for processing and I read about that before online. Didn't see it in the Poweramp audio info though so I wanted to know if it was happening or not. Not that I could hear a difference or anything, just looking to prevent unnecessary battery consumption.

As I said above, some Android devices do default to 48kHz output in their firmware, but by no means all. And activating hi-res (but at 44.1 output) can usually overcome that anyway.

You'd see it in the audio path display if yours was doing that - but there would be next to no extra battery consumption even if it was happening though.

Timely topic for me.  I just got a Shanling M3X DAP and like you noted, the only way I can force Poweramp to output at 44.1kHz is to force it through Hi-Res.  Otherwise, if I select "OpenSL ES" as my output, it defaults to 48kHz, and is not allowing me to change it to any other frequency.  And if I enable DVC, it changes to 384kHz.
