More Android resampling literature here. We will likely see resampling minimized in Android N. Also I'm not sure that this info covers USB output as well.Very interesting. I'll have to check out the Recovery. Thanks for sharing!
Maybe see if the app Audio Buffer Size can tell you anything useful. It measures output sampling rate. It takes about two minutes to fully run.Also, I'm not convinced Android actually upsamples to 192k. Is there any other source of that info besides the light color on the Mojo? The audio_policy.conf file doesn't go past 48k, and the Audio Buffer Size app tells me my output is 48k. I'll try to dig up more info.
