I have a camera that records audio in lpcm and no way to change the codec.  When played through heresphere it has a very loud static in the background that shows the audio codec as raw.  Within vlc it sounds correct with lpcm.  Instead of needing to post process every video it'd be great if it worked.

I can also give a small video file if would help on your side.

Thanks.

These are the supported formats in exoplayer: https://developer.android.com/guide/topics/media/media-formats

According to the specs, raw pcm sampling rates are limited to 8000, 16000, and 44100Hz.
