Hi,
You should override this into s24le:2.0 - yes. Further you should set
bitperfect to avoid resampling issues and the software volume control.
The DSP device will then refuse to open in any other ways than what is
printed in dmesg, with regards to sampling rate and sample size and
channels.
In 11- and 12- you can simply put dev.pcm.4.rec.vchanformat=xxx in the
kernel environment (man kenv) or in /boot/loader.conf (requires reboot)
and these settings will be programmed automatically for pcm #4 every
time you plug this device.
At home I'm using:
http://www.music-group.com/Categories/Behringer/Mixers/Digital-Mixers/X32-RACK/p/P0AWN
Which I'm very happy with. It works well with FreeBSD and is controlled
via a wireless pad (iOS or Android at your choice).
