Bug 288801

Hello,
unfortunately I do not have any of those models in my office. But as I found,
the problem is in a sound module. Guys from alsa are working on it.

Could you try plug earphones in and check if the sound is working with disabled
speakers?

One of workarounds is to unload a sound module (snd-hda-intel) before suspend
and after laptop wakes up, load this module again.

I will try to find out more informations.

Zdenek,
If you want to test, i have the machine here and could assist you with it.

Go to /etc/pm/config.d/. Check if there are any files. If so, look into them and
try to find a line with SUSPEND_MODULES. If you find such a line, append
"snd-hda-intel" as another module. If there is no such a line or in the
directory /etc/pm/config.d/ is not any file, then create new one with the name
"modules". Write into it SUSPEND_MODULES="snd-hda-intel" and save it.

Then try to suspend/hibernate a laptop via gnome-pover-manager. Also try to
suspend/hibernate a laptop by running command pm-suspend/pm-hibernate in a
terminal as root.

thanks, Zdenek

Well,
 what is happening is that the function modunload() in
/usr/lib/pm-utils/functions is not able to unload the snd_hda_intel module
strangely enough when i try to unload it myself through modprobe -r or rmmod, it
does not unload, it shows having a dep, but does not show on what it depends on

[root@huzaifas ~]# lsmod | grep snd
snd_hda_intel          24025  1 
snd_hda_codec         202305  1 snd_hda_intel

snd_page_alloc         13641  2 snd_hda_intel,snd_pcm


this clearly shows that snd_hda_intel is depended on somthing, but does not show
what?
so the modunload function cannot remove it and hence the purpose is not solved.

snd_hda_intel is used by some sound applications (probably mixer, or arts,...),
so you have to stop those applications. Then, the module could be removed. But I
think, this is already too complicated.

Let's try this workaround.
In /etc/modprobe.conf, add:

options snd-card-0 model=3stack
options snd-hda-intel model=3stack

Reboot a laptop and then try to suspend/hibernate.

Not working with that,
mixer is depenent to snd_hda_intel,so when i remove mixer, it works fine 

Anything on this yet?

Hi, this bug happened to me on Fedora 7 and, sadly, continues on Fedora 8 on
this same hardware. Since this bug is about RedHat EL 5 should I file a new bug
for fedora? Or is there any debug info I can get to help fix this?

Is this still an issue? My D630 running 5.3 appears to have working sound after resume. There have been significant ALSA updates to provide HDA support, so I suspect that this bug has been fixed since the last update.

works for me on a 5.3 machine

Since the bug reporter says it works in RHEL 5.3, I am going to close this as CLOSED WORKSFORME.
