[PROBLEM] How to check if hardware volume control over I2C works in AK4490 and USB XMOS control

[Tim Curtis]

If Linux/ALSA recognizes the Hardware volume controller the USB chipset it will show up in the alsamixer utility. The USB device should be assigned to ALSA card 2 in moOde.

Code:

alsamixer -c2

You can also look in the Moode startup log to see if a Hardware volume controller was detected or examine the output from the alsacap (ALSA capabilities) utility.

Code:

moodeutl -l

sudo alsacap
