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.

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:

    snd_hda_intel 337192 0

    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) wrote :

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.

Changed in pulseaudio:
status: New → Incomplete

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

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