How can I simply convert audio from Devialet to Linux command line?

You can also look in /proc/asound, maybe /proc/asound/card0/pcm0c/info while playing and see if it displays a sample rate and other information

EDIT: cat /proc/asound/card0/stream0 may be better...

Code:

$ find /proc/asound/ -iname E20
/proc/asound/E20
$ ls -lAh /proc/asound/E20
lrwxrwxrwx 1 root root 5 Jul 28 22:28 /proc/asound/E20 -> card2

Code:

$ exa -T /proc/asound/card2
Unable to determine time zone: No such file or directory (os error 2) <- All FSes can't be ZFS ... ;-p
/proc/asound/card2
