Example of trying to force 24 input on a DAC using "hw" which does not
support 24
Squeezelite can't open the device each time it tries, but it keep trying
and doesn't stop - no indication of error. Logging is necessary.
Code:
--------------------
$ ./alsacap -d hw:system,0
*** Exploring configuration space of device `hw:system,0' for playback ***
1..2 channels
Sampling rate 6400..48000 Hz
Sample formats: S16_LE
Significant bits: 16
