I've been having trouble accessing S24_LE audio. The driver for the soundcard claims it is supported (or at least it lets me access it) but any time I choose S24_LE as the audio input format I get nothing but noise. S16_LE does work.
I've tried both formats using arecord as well as with RtAudio in a C application.
Is S24_LE actually supported or is this an error in the driver? Has anyone else encountered this issue?
