However, I heard that this card only works as 16bit/44.1kHz on Linux. How do I check the actual bit resolution and sampling rate the sound card uses? Supposedly by starting playback and entering some command line commands to read the actual values.
Using these instructions from a forum I was able to check the sample rate by doing
I had to poke around and figure that
