No sound on Dell XPS after suspend (ALC275)

[Michael]

Dell XPS One 2710, Ubuntu 12.04, Kernel 3.2.0.31 or 3.2.0.32 or 3.6.2

Sound works out of the box, until machine is supended to RAM. After suspend and resume, no sound at all.

A suspend to Disk and resume restores sound!

It is NOT possible to unload snd modules.

sudo /sbin/alsa force-unload:

(failed: modules still loaded: snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-timer snd-page-alloc).

All information in the net either is depreciated (using acpi_suspend) or refers to chips that have options (e.g. modprobe snd_hda_intel option=acer). There is NO documentation about options of the ALC275 chip.

Anybody has a solution to this?

Thanks

Status changed to 'Confirmed' because the bug affects multiple users.

Same here on 12.10.
I'm on a HP 6730s.

sudo lshw output: http://pastebin.com/vh3SGcZa

Can't sudo modprobe -r snd_hda_intel. It gives FATAL: Module snd_hda_intel is in use

/etc/modprobe.d/alsa-base.conf content: http://pastebin.com/yvArB2ex

In /var/log/syslog I found the following:

kernel: [ 33.847111] pci_pm_runtime_suspend(): azx_runtime_suspend+0x0/0x40 [snd_hda_intel] returns -11

[Michael (auslands-kv)]

Just a small update:

Tried kernel 3.7.1, 3.7.2 and 3.8.0-rc3, all with the same result.

It seems there is no chance to get sound working after suspend on ALC275 systems :-(

post the output of alsa-info.sh before suspend and after resume

Hello

good to see that someone is taking care of this bug.

I attached the requested diff.

Hope we can fix it.

Cheers,

>kernel: [ 33.847111] pci_pm_runtime_suspend(): azx_runtime_suspend+0x0/0x40 [snd_hda_intel] returns -11

can you post those messages in the system log during the suspend and resume ?

[Michael (auslands-kv)]

I guess we probably have two different problems here. I don't have any of these azx_runtime_suspend messages that Mauro has.

I attach alsa-info-after-suspend (which also contains some syslog messages).

Tell me, if you need anything more. I really want to get sound working after suspend.

Thanks

Michael

[Raymond (superquad-vortex2)]

both of you only posted the diff

please post the output of alsa-info

[Afro (amilan-inlogic)]

Hi Raymond,
see before and after outputs.

[Raymond (superquad-vortex2)]

Afro

your alsa-info are missing the output of alsactl which show the state of Jack detecting

[Afro (amilan-inlogic)]

Hi Raymond,
i did with alsactl option.

[Michael (auslands-kv)]

Please find attached alsa-info-before-suspend.

For alsa-info after suspend please see #8.

Thanks

Hi, Daniel,

Appears to be fixed entirely now. I was running Ubuntu 12.04 when I first encountered the bug, and if memory serves it was fixed at least a year or two ago. I'm currently running 16.04.

Thanks for responding.
