[alsa-devel] bit depth issue for Scarlett 2i4

Hi ALSA devs!

I recently bought a Focusrite Scarlett 2i4 which is advertised as being capable of recording at a max of 24bit/96Khz but when I run alsacap it reports it as 32bit:

./alsacap -R -d hw:1 *** Exploring configuration space of device `hw:1' for recording *** 2 channels Sampling rate 44100..96000 Hz Sample formats: S32_LE Significant bits: 32

It does seem to record OK but that output seems wrong and I'm slightly concerned about the waste of disk space when multitracking if I end up with 32bit files but only 24 of those bits per sample are actually being used.

Thanks for your help!

Dan
