No sound on Intel DQ965GF motherboard

[Eric S. Raymond]

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
http://www.linuxquestions.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.

    snd_hda_intel 337192 1

On the DQ965GF, here are the sound device lines:

    usbcore 161584 8 usbhid,snd_usb_audio,snd_usb_lib,xpad,gspca,ehci_hcd,uhci_hcd

Note that snd_hda_intel has no users and that snd_usb_audio has 1.

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.

ESR,

Can you try this again in Ubuntu 8.04?

[Daniel T Chen (crimsun)]

Eric, to further diagnose this symptom, I need additional information, namely output from `grep snd-usb-audio /etc/modprobe.d*/* /etc/modules'.

Also, please note that you can migrate which PulseAudio stream is routed to which audio device using the `pavucontrol' program.

[Daniel T Chen (crimsun)]

To triagers: do *not* mark this bug as Invalid if Launchpad has marked it for expiration.

[Eric S. Raymond (esr-thyrsus)]

Doesn't reproduce on 9.04. I think you can mark this Fixed.
