[alsa-devel] intel-hd on an intel G33 motherboard

> I reopened my shuttle case, closely inspected the motherboard and I think I found the issue. The onboard sound was factory set off (jumper), something which I must admit I did not check. However, I find it hard to imagine that XPC would sell their barebones with onboard sound off as a default. Even more weird, the headphones work when the onboard sound is "off".

I checked the Inspiron 530 hda routing and it seems that the front
channel sound is sent to all DACs. I get front speaker sound from all
output pins and they can be muted in the corresponding mixer amp-in.
This is weird, I'm starting to suspect that speaker-test is writing to
the wrong channels.
