Solved forcing off the computer – endlessly waiting for sound application to exit at sleep/suspend time

Cath O'Deray · Jun 27, 2021

Note to self, before the change:

pulseaudio --start --log-target=syslog

Solution

… disable pulseaudio completely, if after that everything still works as expected.

Open /usr/local/etc/pulse/client.conf and uncomment the line with

Code:

autospawn=yes

and set it to no. …

Done, then a shut down to single user mode, then exit to multi user mode and touch wood, things seem to be fine. Things are audible in at least:

Chromium
Firefox
VLC media player.

Working without PulseAudio is not an option for me.

In retrospect, I should have been clearer.

I did, previously, experiment with forced deletion‡ resulting in at least one thing broken. I can't recall what was broken but at the time, the breakage was a showstopper.

I hope to not encounter a show-stopper with PulseAudio not automatically spawning

When autospawn is enabled (the default), I do wonder what triggers the automation but for now, I'll be happy with fewer worries before sleeping the computer.

‡ For reference only, things that would have been deleted if I had not applied force:

Code:

# pkg info -x pulseaudio | sort
linux-c7-pulseaudio-libs-10.0_3
pulseaudio-14.2
pulseaudio-qt-1.3
# pkg delete -n linux-c7-pulseaudio-libs

Audio Mixer (audio/gtk-mixer) and KMix audio/kmix)

KMix is a runtime requirement {link removed} for KDE Multimedia {link removed} (multimedia/kdemultimedia).

Since I forced deletion of KMix, touch wood:

the pre-sleep script no longer kills kded5 (x11/kf5-kded)
after waking the computer from sleep I no longer need to manually run kded5 &
the system tray looks good (it never looked tidy after a manual run of kded5).

On one hand, I miss the system tray volume control of KMix.

On the other hand, I could never remember which of the KMix buttons from the system tray pop-up was intended to open the main window. (More often than not, I accidentally got the configuration window, from which the main window could not be opened).

Audio Mixer has a main window and system tray item that are non-ambiguous. The main window is particularly nice.

Did you try audio/dsbmixer? It uses Qt and comes with a system tray controller.

If you prefer to stick with gtk-mixer (or whatever mixer you want), you can use audio/volumeicon to get a system tray controller and notifications.

Thanks,

Its system tray controller seems to offer no more than is offered by the controller for Audio Mixer.

Its system tray controller doesn't work properly with the ring around my trackball.

Done, with verification that pkg upgrade does not automatically reinstall the true audio/kmix:

The single long line for the description was not ideal, so I deleted the package, re-edited /usr/home/grahamperrin/dev/kmix-fake-manifest then reused pkg-register(8).

~~My current edition of the script:~~

That edition of the script never put the computer to sleep, probably due to an editing error by me. (It did make the computer sleep-ready, but never reached the acpiconf command.)

I can't be bothered to fix it. With the affected part commented out, the computer does sleep, touch wood.

For reference:

KDE: change default sound mixer applet

The kmix mixer is being replaced by the more flexible and integrated plasma-pa mixer from audio/plasma5-plasma-pa

…

Test result – success:

I ran the suspend script whilst listening, without PulseAudio, in Firefox
scripted killings included the tab where there was playback
pictured above, wake from sleep was good.

I reopened GTK-Mixer a.k.a. Audio Mixer, began listening to YouTube in another tab:

the Audio Volume applet finds no input or output device because PulseAudio is configured to not autospawn.

One more thing that will come with PulseAudio by default

Did the default behaviour change recently? This wasn't the case not so long ago.

AFAIK, programs which uses pulseaudio for running can still spawn a pulse session.

No, the configuration is at the head of this page.

Can you suggest an application with which I can test whether this prevents sleep?

Ongoing discussion:

Not entering sleep state due to audio

On an Intel x86 based FreeBSD 13.0-RELEASE-p4 machine, putting it to sleep (using zzz) while FireFox has a tab streaming music makes the system not going to sleep and instead printing these messages over and over (indefinitely): pcm7: unregister: mixer busy pcm7: Waiting for sound application...

(Whilst things are Solved for me, the bigger picture is not ideal.)

I encountered similar issues with my FreeBSD 13.0-RELEASE-p7 install last night. I thought maybe a gnome issue, but indeed firefox was running and I am using an USB sound device.

Please feel free to test the following patch, which fixes this bug:

NAME=FreeBSD
VERSION="13.3-RELEASE-p4"

I briefly looked through the posts and this bug still exists. It doesn't have anything to do with pulseaudio but you may have found that out already. I am using a new 4 port dual monitor switch with 2 Dell servers that lets me use 2 monitors each or separately and was overjoyed that I was able to use an external USB sound card with the switch without having to climb under the desk and swap my speakers or external usb sound card, until I realized on FreeBSD my mouse and keyboard wouldn't reconnect. Fiddled with xorg.conf settings and rc.conf hald dbus etc and found a repeating error in /var/log/messages...

Waiting for sound application to exit!
Aug 5 17:11:00 superbee kernel: pcm4: unregister: channel pcm4:virtual:dsp4.vp0 busy

Got rid of all apps using sound and I was able to switch and get back keyboard and mouse. For some reason I can't get pulseaudio to start anymore something about directory permissions and it's not needed anyway. Finally found that removing xfce4-mixer, which does not show up a separate process so would be hard to kill, let's me switch with KVM to the Debian server and back with the keyboard and mouse working. A little more troubleshooting, found that if I view a youtube page in firefox and pause it, switching does not work, but back page and it does work. Tried several volume control apps and mixers, used debian by ssh to kill the apps and or firefox many times and as long as anything is using the sound device, usb devices all lock up and KVM switching won't work. The best workaround at this point is to pin gtk-mixer to the xfce4 taskbar and run it to adjust volume then close it and then make sure that anything else using the sound device is closed before switching, so in firefox just back page.

Thanks, John

And, wait for fixes from the developers....

The cherry-pick was to stable/14 alone, excluding stable/13.

Thanks, John

Please upgrade to 14.1-RELEASE; read notes for both 14.0 and 14.1 before doing so.

Solved forcing off the computer – endlessly waiting for sound application to exit at sleep/suspend time
