CPU time limit stops deamon

[sladi]

I have a problem because Pulseaudio just stops. I always listen to an internet readio mms stream and suddenly the music stops. I then have to restart Pulseaudio which I can use until the next shutdown of it. People in the IRC helped me to post the output here: http://pastebin.com/m286d0691 Then I also tried with '--no-cpu-limit' option. This caused Pulseaudio to use 99%-100% CPU according to top and I had to 'kill -9 PID#' it. The last line was 'I: protocol-native.c: connection died.' After that I did 'strace pulseaudio'. The output is here: http://pastebin.com/m72c9df3c

I use Debian Testing AMD64 an Creative X-Fi card, Pulseaudio 0.9.10, Kernel 2.6.25-2 and I listen using Totem Gstreamer Mozilla plugin (Iceweasel 3.0.1). My ~/.pulse/default.pa is here: http://pastebin.com/m721a74f3 ~/.asoundrc is: http://pastebin.com/m3b6af4f7

I wanted to add that I have an AMDX2 dual core CPU. Also this seems similar to #245 but I can pause a stream just fine without 100% CPU usage.

Please note that the htting the CPU time limit is not a bug in itself. It is just the protection to not block your machine indefinitely in case a real bug happens.

Some versions of ALSA's "multi" module triggers readability too often. Please figure out if "multi" is in the pipeline for the alsa device that is opened.

I have a core2 duo and I am also having this issue i use Ubuntu 64bit. I get the soft and hard cpu time out and pulse shuts down. I ran pulse from the command line after words and added the no-cpu-limit but it still stops working but it did not shut itself off like before. It put one of the cores of my cpu to 100. I could not get sound to play until i manually killed pulse and restarted it.

Everything works fine for like 10 minutes then it crashes. I have run tests to see if it crashing on a particular program but it crashes no matter what is using it. i will play music on a fresh reboot of the entire system and it will crash after a few minutes. it crashes on movies, music and flash. Each time pulse crashes it takes the other programs with it.

I use onboard sound from my Gigabyte GA-EX38t-DQ6 its a Realtek ALC889a in PA manager it show up as alsa_output.pci_8086_293e_sound_card_0_alsa_playback_0 and is described as ALSA PCM on front:0 (ALC882 Analog) via DMA i have it hooked up throught eh SPDIF

If you want any information let me know

Lennart, I don't have multi in the ALSA pipeline.

I responded to Lennart in the mailing list but maybe I should add it here. :)

I'm also experiencing the same problem. This typically happens for me when using Amarok w/ the Xine backend going to pulseaudio.

When I run it from the cli w/o -D I see the Soft/Hard CPU errors shortly after the music stops.

If I run it with the '--no-cpu-limit' the playback lasts longer but then the audio cuts out and pulseaudio uses 100% of one CPU just like others.

Let me know if there's anything I can do to help debug this.

pulseaudio 0.9.10 - pulseaudio-0.9.10-2.fc9.x86_64

[silfreed]

pulseaudio -v log output when CPU time limit is exceeded (updated w/o line wraps)

[silfreed]

pulseaudio -v --no-cpu-limit log output when sound cuts out and CPU goes to 100%

[silfreed]

Attached are two verbose log outputs from pulseaudio runs; one with and one without --no-cpu-limit. There seems to be very little difference (other than I have to background and kill -9 pulseaudio when it dies from using the --no-cpu-limit switch).

This time adding the switch didn't extend the time audio worked for me like it did the previous time; both times audio only lasted for 1-2 minutes before cutting out.

Currently I have a VLC process eating up 200% cpu (dual core) that *may* be affecting how quickly pulseaudio cuts out, but I have had lots of experience previously where pulseaudio cuts out quickly while under low CPU usage.

The only other anecdotal evidence I can offer is that it seems that pulseaudio will run longer between cutting out if I let it dead for a period of time before I restart it. I haven't performed *any* analysis to determine if that's actually the case or not.

I'm experiencing the same problem on my machine. I'm running Fedora 9 x86_64, which currently uses PulseAudio 0.9.8. I've experienced this problem since this summer (not sure exactly when).

The machine is an Athon X2 3800+, with AMD690 chipset ("shared memory" - I don't play games, so I don't care about blazing graphics performance) and the ATI SB600. I believe the codec is Realtek ALC883.

$ uname -r -v -m -o
2.6.26.6-49.fc8 #1 SMP Fri Oct 17 15:33:32 EDT 2008 x86_64 GNU/Linux

$ rpm -q pulseaudio
pulseaudio-0.9.8-5.fc8

$ cat /proc/asound/cards [[BR]]

 0 [SB             ]: HDA-Intel - HDA ATI SB
                      HDA ATI SB at 0xfe020000 irq 16

The only message from the driver I see at all occurs always right after starting PulseAudio: Nov 20 09:11:37 freebie kernel: hda-intel: Invalid position buffer, using LPIB read method instead.

I've tried using the position_fix parameter, but to no avail. To be honest, I didn't try much with kernel module parameters. I don't have issues with my sound not working at all or excessive skipping, which is what usually pops up when you look for snd-hda-intel parameters.

I can actually somewhat reproduce the problems: when I scroll a page in Firefox, either by keypresses or mouse, music sometimes skips or even hangs completely. If I restart PulseAudio by hand, the problem will usually pop up again, and I'll get the dreaded CPU limit exhausted messages. Other events seem to trigger this as well (eg. screen unblanking, switching desktops), but not nearly as reliably.

I've also seen and heard it stop when I wasn't even close to my computer, so user input is not the only trigger. Nor does my system have to be really busy when sound goes dead.

Applications don't seem to matter. I have the same issues with Amarok, vlc, mplayer and Flash.

I hope this is useful. Feel free to contact me if you need more info - it is really annoying. Last few weeks, I sometimes had to restart the bugger 10 times a day.

I have used pulseaudio 0.9.13 since the end of October when it became available in Gentoo, and never encountered this problem. I just upgraded to kernel 2.6.28, and immediately this problem appeared. I was able to avoid it by using the --no-cpu-limit parameter, and haven't encountered any negative affects of that yet. I hope this information helps.

Just to bump this and to add more detail, I am having the same issues in Fedora 10 x86_64. I am using the coax PCM output on the Soundblaster card.
