Intel HDA / Realtek ALC885: No sound after resume

What is the output of:
lspci -vn | grep -A 1 0403

Also, can you please double-check that *every* sound device works with that model? By that I mean all output jacks, all input (mic) jacks, any built-in microphone you have, and the speakers?

Please also attach the full output of:
cat /proc/asound/card*/codec*

Hi! I have the same problem and want to add some information.

The following fix works (temporarily):

https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/202089/comments/19

This seems to indicate a kernel bug.

The suggested fix worked for me:

>> I was able to fix the problem by adding the following line to
>> /etc/modprobe.d/alsa-base :

>> options snd-hda-intel model=6stack-dig

Now my computer suspends/resumes properly.

>> Also, can you please double-check that *every* sound device works with that model?

"model=auto" should work with every sound device, but there's a bug that prevents it from working on resume.

See this document:
http://bugs.archlinux.org/task/10495

"model=6stack-dig" should NOT work with every sound device. "model=auto" is the default, but, like I said, it's broken.

Here's the list of values for the model parameter:

http://www.mjmwired.net/kernel/Documentation/sound/alsa/ALSA-Configuration.txt#769

As you can see, it's quite an extensive list, and sadly it's very hardware specific. So there's really no generic fix that the Ubuntu developers can deliver. The only solution appears to be an updated kernel with a fixed snd-hda-intel module.

Hi, and sorry for not having answered for so long.

Confirmed: Every device works.

Pls. cp. the attached file.

I have the same trouble.

$ lspci -vn | grep -A 1 0403
00:1b.0 0403: 8086:293e (rev 02)
 Subsystem: 1462:7357

I use following line in /etc/modprobe.d/alsa-base
options snd-hda-intel model=6stack-dig

It also seems to work with the following option I used before
options snd-hda-intel model=hippo

If I run the following command after resume, the music player resume playback.
$ pasuspender echo

There is an other strange behavior :
- After resume, go to the console (Ctrl+Alt+F1)
- Go back to X session (Ctrl+Alt+F7)
=> the music player resume playback (without running any command).
Can someone confirm this ?

I can confirm: after switching to console and back sound playing is ok again.

Ubuntu 8.10,
linux-image-2.6.27-7-generic 2.6.27-7.16
alsa-base 1.0.17.dfsg-2ubuntu1

Also if I resume, quit the music player and then switch to console and back whan switching back a fragment of the last played music can be heard.

In /etc/modprobe.d/alsa-base I have:
options snd-hda-intel model=6stack-dig

$ lspci -vn | grep -A 1 0403
00:1b.0 0403: 8086:293e (rev 02)
 Subsystem: 1043:8277

I can give more logs/info if needed.

I can confirm this is a problem for me and all of my colleagues using Thinkpads T60/T61.

using "options snd-hda-intel model=thinkpad" apparently solved the issue. I'll report back if I find more problems.

Can you also confirm this issue exists with the most recent Karmic Koala 9.10 Alpha release? ISO CD images are available at http://cdimage.ubuntu.com/releases/karmic/ . If the issue remains with Karmic it would be great to then also test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Thanks in advance.

Confirmed on Koala alpha-6

I have a gateway E-475M which uses the HDA driver

The output of
lspci -vn | grep -A 1 0403
is
00:1b.0 0403: 8086:284b (rev 03)
 Subsystem: 107b:0370

I have not applied the fix yet.

Additional note. In order to restore sound, I quit from the rhythmbox applet
and restart rhythmbox from the applications menu.

I also experience this symptom.

Can confirm on Karmic beta, updated till 21/oct/2009. No sound after resume/suspend, only fix is a reboot. Tried alsa --force-reload and a bunch of other things.

gateway:/data/work/kernels/linux-2.6.31.4> lspci -vn | grep -A 1 0403
00:1b.0 0403: 8086:284b (rev 03)
 Subsystem: 107b:0380

Have not tried above suggested fix yet.

Thanks

Gertjan

Addendum: logging out, (killing pulse-audio) followed by alsa force-reload re-instates sound.
