Last modified: 2013-04-09 06:23:26 UTC
Latest working kernel version:
Earliest failing kernel version:
Hardware Environment: ASUS P5LD2-VM => ICH7 + intel_hda audio ( realtec codec ALC882 )
No sound after resume. If i reload snd_hda_intel and suspend/resume agene sound will work.
I disable any desktop enviropment to make clear there is no other script makeing this.
1. (sound working) lspci -vvxxxs 00:1b.0 > lspci1
2. echo mem > /sys/power/state
3. resume ( no sound ) and lspci -vvxxxs 00:1b.0 > lspci2
4. rmmod snd_hda_intel && modprobe snd_hda_intel ( sound working now )
5. lspci -vvxxxs 00:1b.0 > lspci3
6. echo mem > /sys/power/state and resume ( sond working )
7. lspci -vvxxxs 00:1b.0 > lspci4
diff lspci1 lspci2
< 40: 03 00 00 03 00 00 00 00 00 00 00 00 00 00 00 00
> 40: 01 00 00 03 00 00 00 00 00 00 00 00 00 00 00 00
betwene lspci2 , lscpi3 or lspci4 no difference.

I tested kernel 2.6.22 . Sound is working after resume.
2.6.22 use irq 20 for HDA Intel
2.6.24 use irq 19
both have after boot pci 0x41 = 0x03 and after resume 0x01
Will you please attach the output of acpidump?
Please try the boot option of "acpi_new_pts_ordering" and see whether the problem still exists?

"acpi_new_pts_ordering" do not make any difference.
Ok. It seems like not acpi issue, it was brocken after some alsa commit: bisect/good bd45ac0c5daae35e7c71138172e63df5cf644cf6
i didn't get to test more. It it bracke some dependency.
It is my first time i use git bisect, so i houp i did't any thing wrong. Here is result of my tests:

This patch revert the part wich was brocken for me.
Re-assign this bug to the patch author. :)
Could you run alsa-info.sh before and after suspend (better with --no-upload)?

The pin-default values are changed during suspend/resume, and this is not what the sound driver does. So, something is screwed up, at least.
What happens if you reload the sound driver after resume? Is the alsa-info.sh output identical with the state before suspend?
Also, could you check whether the current Linus git tree works? There are some fixes for auto configuration of Realtek codecs since 2.6.25...
This reports was made with latest linus git.

May it be not a suspend issue but some boot initiation issue? It seems like pci space was reconfigured after suspend.
I made somole test,
- blacklisted snd_hda_moduel,
- rebooted and suspendet S§ and resume
- loaded module ( sound working )
- supend && resume ( sound working too )
Sound working OK if setpci -s 00:1b.0 0x40 return 0x01
but after fresh boot 0x40=0x03.
Is it possible to make on boot, setpci -s 00:1b.0 40=01 ?
Seems like there is some thing wrong with autoconfiguration from BIOS. I found new work around, just set module option model=6stack-dig and it working for me without any problem ;)
Could you check whether the latest tree still has the same problem?
seems to be fixed now. than you.
Thanks for checking!
