Hmm, ok. That line seems to correspond, then, to this line in my
/etc/modules.conf:
options snd-usb-audio index=0,1 pid=0x0006,0x1015
I see that I have "snd-usb-audio" and you have "usb-audio". Is this one
of the instances where the "snd-" prefix is no longer valid? That also
appears earlier in the file:
alias snd-card-0 snd-usb-audio
alias snd-card-1 snd-usb-audio
Do I need the "id" argument? And do I understand correctly from other
docs that this needs in my case to be "Keystation" as reflected in my
/proc/asound/cards file?:
0 [REC ]: USB-Audio - UA-30 (44100Hz, Analog REC)
Roland UA-30 (44100Hz, Analog REC)
1 [Keystation ]: USB-Audio - Keystation
M-Audio Keystation
