[SOLVED] Slow shutdown: Waiting for process: pulseaudio

Hey,

since some weeks my system takes forever to shutdown.
After the log "Reached target Power-Off" it constantly waits for pulseaudio and after some time it shuts down.
For some reason the "systemd-shutdown[1]: Waiting for process: pulseaudio" message does not appear in the logs so i attached a picture of it

Error Message Picture: https://postimg.cc/XpwyTh10

sudo journalctl -b -1:

Mai 13 16:29:42 tomarch systemd[1]: Reached target Power-Off.

Why does it take so long to kill pulseaudio ?

Re: [SOLVED] Slow shutdown: Waiting for process: pulseaudio

Untruncated journal (or at least the entire shutdown sequence)? I suppose some actual sound card component is borked and pulse can't properly detach from it. The pulseaudio daemon that's hanging is the one opened by GDM, do you use some "volatile" sound card, like bluetooth headset or so?

Also please use [ code ] [ /code ] tags instead of [ quote ]  for output.

Yes, i have two usb soundcards and a bluetooth dongle.

Here is the complete journal of sudo journalctl -b -1
https://pastebin.com/BrPby2W5

I just rebooted and got the same problem.
Here is the seconds log: https://pastebin.com/FPT9fz1y

It could be that my onboard soundcard is broken. Thats why i am using the usb dongles.

Re: [SOLVED] Slow shutdown: Waiting for process: pulseaudio

Ok, i kind of solved it. There was an error message:

kernel: iommu ivhd0: AMD-Vi: Event logged [INVALID_DEVICE_REQUEST device=00:00.1 pasid=0x00000 address=0xfdf8010020 flags=0x0a00]

I added the kernel option iommu=soft in /boot/loader/entries/[yourconf].conf as described here: https://bbs.archlinux.org/viewtopic.php?id=167838
Now the error message is gone but my onboard soundcard is not working anymore. But since i use the usb cards anyway this is ok for now.
I have no idea what iommu does, maybe one can activate the soundcard again by using an other value than "soft".

@V1del, thanks for your help .

Edit:

As i am using an amd system i changed the kernel option to amd_iommu=off as described here: https://bbs.archlinux.org/viewtopic.php?id=168555.
This reduced the cpu load. Before i had one CPU thread at 100% now all threads are nearly idle. The soundcard is still not working.

SOLVED

I updated the bios of my MSI-A78M-E45 to the latest version 25.6 and now everything works without additional kernel options and also with reduced cpu load.
