no sound after resume from suspend/hibernate

[alkamid]

Binary package hint: pulseaudio

I'm running Ubuntu 8.10 Intrepid Ibex on a Lenovo ThinkPad T61 laptop.

Usually, before I hibernate my computer, I pause the music. Then, after resume, it won't play again. I tried it with Exaile and Totem. I have to restart those apps to get the sound working again.

I guess its PulseAudio issue, as the problem disappears as I change Music and Movies: Audio Playback to OSS (it's in System->Preferences->Sound).

Here's what alsa-info script says:
http://www.alsa-project.org/db/?f=73a55b074ca93e7910dce77a039b0bdd1889c9a2

Is there any further information I can provide?

I have a Lenovo R61 and the sound with Intrepid 8.10 and kernel 2.6.27.7 is way over-modulated and has no sound after suspend also. The sound with Intrepid 8.10 and kernel 2.6.24.21, is fine for modulation and after suspend. With both kernels, the input mic does not work.

Lenono R61 here as well pulseaudio seems stuck after suspend... killall pulseaudio then pulseaduiod - D seem to restart everything

I can confirm this same behavior on my Lenovo T61 running up-to-date Intrepid Ibex. Sound is dead after resuming from suspend mode. However, the problem is not consistent. Sometimes sound works after resume, sometimes it doesn't. I have sound preferences set to "Auto Detect" in System->Preferences->Sound->Devices

It appears that if the laptop is suspended only briefly (< 1 minute) sounds works fine after suspend-resume. The problem with no sound occurs more often if the laptop is suspended for longer times (~ 30 minutes). When that happens I get errors like these in /var/log/syslog

Nov 5 15:51:01 xxxxx pulseaudio[6088]: module-alsa-sink.c: Got POLLERR from ALSA

The following restores sound again:

 killall pulseaudio
 /usr/bin/pulseaudio -D --log-target=syslog

When I try
killall pulseaudio
/usr/bin/pulseaudio -D

I get this:
Nov 6 11:50:08 adam-laptop pulseaudio[19293]: ltdl-bind-now.c: Failed to find original dlopen loader.

Thinkpad T60, experiencing the same issues.

Killing pulseaudio (with pulseaudio -k) and restarting it gets sound working again.

IBM ThinkPad T42, same bug and same workaround as for the others.

Confirmed.. restarting pulseaudio after wake up fixes sound play

Confirmed for Dell Latitude D520

Sometimes it just works (10%), sometimes restarting Rhytmbox is enough (30%), but most often killing and restarting Pulseaudio is the only fix (60% of the cases).

I'm on Intrepid, with the following version of the pulse audio package:
  Installed: 0.9.10-2ubuntu9
  Candidate: 0.9.10-2ubuntu9

The only useful parts of dmesg that I could find are:
[ 4954.143585] rhythmbox[7173]: segfault at 48 ip 00007fcc09fe0d8a sp 00007fff12b813f8 error 4 in libpython2.5.so.1.0[7fcc09f0e000+13c000]

If you need anymore info please let it know. I can reliably reproduce the error and provide extra info if needed.

Same on Gateway MT3418....

[captain-wifi (laukokpin)]

running ibex on my compaq presario v3000. audio after suspend was working. Until a kernel update a week or two ago. now after suspend. no audio.

please let me know if you want more info from me.

Hi...... restarting pulseaudio works for me.. but after restarting pulseaudio pidgin takes memory until 900MB so i have to kill it

[wahlau (wahlau)]

running 8.10 on T43, observed same problem where sound is missing after waking up from Suspend to RAM. the manual restart pulseaudio trick does bring sound back. /etc/init.d/pulseaudio does not do anything.

the "Failed to find original dlopen loader." error is there, though sound/pulseaudio is loaded.

[wvengen (wvengen)]

bug #202089 looks related and might have a workaround/solution (look near the end of the comments).

[Patrick Wagstrom (pridkett)]

More properly, looking through the comments it appears that this bug is a duplicate of bug #202089. Perhaps someone with a bit more expertise can confirm and mark this bug as a dupe.

Latest Pulsaudio updates are closer. After suspend I only need to run ' pasuspender echo' to restore my sound, even in Firefox, which had required a closedown and restart to work.
