Bug Description
No sound from Intel DQ965GF motherboard. The motherboard uses an 8201H ICH8 audio chip identical to the one actually working in the Lenovo Thinkpad X61 sitting next to it; both are running Gutsy. both load the sound_hda_intel module which is correct for the chip.
The difference is that on the DQ965GF motherboard Gutsy loads a second sound module, snd_usb_audio, and uses that as the default.
aplay -l on the Thinkpad lists "card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]". On the DQ965GF it lists no playback devices.

The device has PCI ID [8086:284b] (rev 02).
This appears to be an Ubuntu-specific error. At www.linuxquesti ons.org/ questions/ linux-hardware- 18/intel- dq965gf- mobo-front- sound-jacks- not-working- 510302/

I found a post implying that at least the rear jacks on the mobo are
active under Fedora Core 6.
This also appears to be a very hardware- configuration- specific error.
I have an Intel HDA audio device on my X61 laptop with PCI ID
[8086:284b] (rev 03) that works just fine. Note the 03 as opposed to
02 subrev.
aplay -l, which is supposed to list sound playback devices, returns no
listing on the DQ965GF. As a check, on the laptop where it works it
returns this:
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
lsmod also returns suggestively different results. On the laptop, its
output includes this line.

On the DQ965GF, the Sound Preferences tab on my Gnome toolbar thinks
the sound device is "USB Device 0x46d:0x8ad (ALsa mixer)". I don't
know what tool GNOME is running to determine this.
