No audio volume

[roadrunner58]

I installed Kubuntu 17.10 on my intel desktop and on my Acer laptop today. I noticed that there is no audio volume and it says "No Output or Input Devices Found" on both computers. The audio volume worked on both computers with Kubuntu 17.04. Does any one else have this problem?

[vinnywright]

no ,,,not @hear , but I did a "do-release-upgrade -d" from a working 17.04

what dose

pactl list sources

show .

and did you check "rite click a blank space in the system tray>click system tray settings>and make sure audio volume is checked.

Yes, the audio volume is checked.

If I click on application launcher, multimedia, volume control, I get a message that says: connection to pulse audio failed because pulse_server in the enviroment x11 root window properties or default-server is mis-configured. Then it says that this can also arrise when the pulse server has crashed.

I'm having this problem too. Same messages people above are getting. Apparently Pulseaudio is refusing to load. On the terminal, I can type alsamixer and it recognize my soundcards (integrated, HDMI and a USB Asus Xonar U5).

Typing "pulseaudio" on the terminal gives me this:

clesio@HAL9004:~$ pulseaudio
E: [pulseaudio] module.c: Module "module-switch-on-connect" should be loaded once at most. Refusing to load.
E: [pulseaudio] main.c: Module load failed.

Have you tried doing a re-install of pulseaudio?

Hi guys, I am lost audio after upgrade from 17.04 to 17.10 as well. In settings is only some Default device.

$ pulseaudio 
W: [pulseaudio] module.c: module-combine is deprecated: Please use module-combine-sink instead of module-combine!
W: [pulseaudio] module-combine.c: We will now load module-combine-sink. Please make sure to remove module-combine from your configuration.

Same problem after upgrading from 17.04 on Dell XPS13-9343.

In system settings I found that I could not start the hardware detection.

I tried to install every hardware driver for soundcards that looked good via synaptics and installed alsa, without any effect.

Any suggestions?? I'd be thankful.
Update; same pulseaudio output as posted above. Reinstalling it doesn't work.

and have seen another comment that:

Okay, editing /etc/pulse/default.pa and commenting the last 3 lines …

###.ifexists module-switch-on-connect.so …
###load-module module-switch-on-connect …
###.endif

seems to solve the issue.

and

https://bugs.kde.org/show_bug.cgi?id=384997

So uptream bug in pulseaudio if that is correct

[corwin78]

I can confirm, that commenting mentioned lines in /etc/pulse/default.pa fixed problem on my ThinkPad W520.

[acheron]

If people are able to, could they please comment on the fix on the launchpad bug report? That will increase the chances of us getting a fix as an update.

[papapenguin]

I had the same problem when upgrading from 17.04 to 17.10 and commenting out those 3 lines solved my sound issue as well.

Now hopefully we can use bluetooth...

[roadrunner58]

Commenting out the 3 lines solved my sound issue for me. Thank you.

[vinnywright]

strange ,,,,,I have those 3 lines @hear as well ,,,,and it is causing me no problems at all so far .

but I do have the http://ppa.launchpad.net/kubuntu-ppa...landing/ubuntu in my sources.list ...so maybe?

Commenting the last 3 lines in "/etc/pulse/default.pa" (using nano), then pressing Alt+F2 and executing "pulseaudio" fixed it for me instantly.

So, the problem is the option to "Automatically switch all running streams when a new output becomes available". I had this marked and after a reboot the bug was triggered. It is a good idea to put this on The Kubuntu website under the known problems, so people can avoid it.
