The device doesn't change the mixer volume internally.
The mute with the button works while _unmute_ doesn't work. It only
mutes regardless how many times you pressed it. The only way to
unmute or adjust volume is to do in software.
I'm wondering how to handle it, since lsusb doesn't show any HID or
even vendor-specific stuff.
The device seems working well otherwise. It can play 6 analog outs.
The digital out isn't tested yet...
FYI, the lsusb -v output is attached below.
