 Posted: Tue Oct 04, 2016 2:25 pm Post subject: My pulseaudio went crazy... stuck in infinite loop? - SOLVED |
 |
|
Hi all, I'm completely stuck on this one and need some help...
Pulseaudio seems to be stuck in a loop creating sources/sinks over and over again and cutting out the s/pdif connection to my stereo every time.
I can open alsamixer and actually watch the s/pdif button flicker on and off rapidly.
I tried setting use="-pulseaudio" in make.conf and emerge -uDN world and after a reboot the problem did go away, which I think rules out hardware/kernel/alsa.
I also tried deleting ~/.config/pulse and that had no effect.
I have no idea what else to try or how to even make a useful search as I'm not entirely sure what's happening here...
Here is a snippet from the output of pulseaudio -v (it just keeps repeating over and over again and got up to number 2208 in less than 5 minutes...)

Any help with this would be greatly appreciated!
Edit; this is a mostly stable amd64 system with a few goodies like KDE5/qt5. The problem first appeared after logging out of X (all the way to tty) and starting it back up.

Thats your user profile
Are there any config files in /etc ? |

There are a few files in etc (I've not touched any of them). I tried moving them away before replying but without them pulseaudio won't start at all.

Have you try to use Pavucontrol and see what you can do in the configuration and other tabs? When Pulseaudio run and take the control of the sound card, Alsamixer is not of a great utility. The USE flags with who Pulseaudio have been compile can have something to do with the flip on and off of s/pdif.

Yep, pavucontrol is essentially un-useable. It constantly flickers and resets itself just like the button in alsamixer. Sometimes it says "establishing connection to pulseaudio" for a moment between flickering, this is partly why I think pulseaudio itself is crashing and restarting over and over again or something.
EDIT: After messing around with /etc/pulse/default.pa for a while without any improvement I decided to try downgrading pulseaudio (from 9 to 8 ) and the problem went away! If I need to I'll just keep it at version 8 for now but I'm still curious what could be causing this. I think this definitely proves it's pulseaudio itself that is the problem (or some misconfiguration version 9 doesn't like).

Maybe an antique kernel. Newer software expects stable kernel.org kernels and not gentoo stable antique ones ... (4.7.x or 4.8.x ...)
WEll it works here but bugs can happen with different setups, so ... Not really a proof that this is the cause
| Code: | qlist -Iv pulse
media-sound/pulseaudio-9.0
ASUS-G75VW roman # uname -a
Linux ASUS-G75VW 4.7.3-gentoo ... |

Yeah I've got 4.4.21-gentoo I suppose that could be considered antique... It's possible I was on pulseaudio 8 and updated it to 9 without noticing while updating world and the problem didn't appear until I restarted X... I'll have to try upgrading the kernel and going back to 9 to see what happens.
I'm not an audiophile though... if sound comes out of the speakers when I want it to, and doesn't when I don't that's all that really matters..

Well this problem.. ahem.. re-emerged after a world update that left me with pulseaudio 10 and no apparent downgrade option less than 9.
After wasting more time on this I finally unplugged the damned front panel connector for my case and viola! Audio works flawlessly!
I've since discovered there are TWO connectors, AC'97 and HD audio (from the case). I think I might have accidentally had the ****ing AC'97 one plugged in all this time, causing audio problems for YEARS! Everything seems to be working fine with the HD connector plugged in now...
So long story short if you have this problem, um, check your connections...  Bogus headphone jack plugged/unplugged events were being generated or picked up by alsa and pulseaudio causing them to cut the digital output and try and switch back and forth between headphone and digital very rapidly...
This one belongs in the old "dumbest things you've done with linux" thread I think
