Comment 6 for bug 1236965

why do your test with 9 channels ?

you should test only 2 , 4 , 6 or 8 channels

speaker-test -c2 -t wav -Dhw:0,0

speaker-test -c4 -t wav -Dhw:0,0

speaker-test -c6 -t wav -Dhw:0,0

seem the driver did not create channel mode switch to retask the jack for external 7.1

speaker-test -c8 -t wav -Dhw:0,0

I guess the config is similar to targa-8ch-dig (notebook with 4 jacks)
