[SOLVED] pulseaudio update breaks sound in kde

mcloaked · 2015-02-13 09:38:38

I just updated my system which brought in pulseaudio updates as follows:

[2015-02-13 09:25] [ALPM] upgraded libpulse (5.0-1 -> 6.0-1)
[2015-02-13 09:25] [ALPM] upgraded pulseaudio (5.0-1 -> 6.0-1)

My desktop is kde4 and since the update I have no sound output. There is no apparent way to change the settings to get the sound to output to the normal channels and I have only a "dummy" output channel available which does nothing. I have looked at kmix as well as pavucontrol settings.

Does anyone know a workaround or a fix for this?

Same here. Also running KDE 4. This is from my journalctl output:

Feb 13 10:49:17 g570-arch pulseaudio[30086]: [pulseaudio] module-alsa-card.c: Failed to find a working profile.
Feb 13 10:49:17 g570-arch pulseaudio[30086]: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="0" name="pci-0000_00_1b.0" card_name="alsa_card.pci-0000_00_1b.0" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes card_properties="module-udev-detect.discovered=1""): initialization failed.

Fixed it by deleting my .config/pulse directory and rebooting.

OK thank you for that useful info. I did the same and rebooted (I tried logging out and back in but that seemed not to fix it after removing the .config/pulse directory). Then I had to go into kmix and and select "mixer", then under the settings pull down item go into audio setup, and going to the Audio Hardware Setup tab, that was the second tab along, and select the correct sound card profile (which in my case was HDMI2). That did fix my sound and everything seems fine again now.

Edit: It seems that the above procedure needs to be executed for every user on the system. It would be nice if there was a cleaner upgrade process that did not necessitate a manual fox for every user though.

Same here too, under XFCE, only journalctl showed nothing wrong :-S

I have just updated a second machine (laptop) and thought I would try to reboot immediately after the update - in that case sound was working fine after the reboot. So perhaps all that is needed for most people is to reboot without doing the above procedure. I have one more machine to update - and I will report back if simply rebooting fixes it as well.

Edit: on a second laptop after updating pulseaudio and the libpulse packages and rebooting immediately, that machine had no sound issues either, and the procedure to remove .config/pulse was not necessary.

From http://www.freedesktop.org/wiki/Softwar … Notes/6.0/

extra-hdmi.conf, which was present in 5.0 and a few versions before that, has been merged with default.conf. The udev rule has been updated accordingly, but these are typically only read at boot time, so in some cases your sound card might not to be detected. We suggest you do one of the following to fix this transitional problem:
Reboot your computer, or
Run "udevadm control --reload" and then "udevadm trigger" (as root), or
Create a symlink from extra-hdmi.conf to default.conf.

I assume you all are using hdmi

On the machine where I had the problem then yes that was the only one with sound through hdmi. Thank you for the additional information which I was not aware of till now.

Just for completion on info - when I checked for the presence of extra-hdmi.conf and default.conf then I didn't see extra-hdmi.conf but there is one default.conf relevant to pulseaudio:

$ sudo find / -name extra-hdmi.conf
$ sudo find / -name default.conf
/usr/share/alsa/pcm/default.conf
/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf
/usr/share/lirc/configs/default.conf
/usr/share/logwatch/default.conf
/etc/xdg/qtchooser/default.conf
/etc/vpnc/default.conf

So I guess that the fix process presumably removed extra-hdmi.conf or perhaps it didn't exist on my system before either?

it was there but was merged into the default.conf hence it isn't there anymore

Thank you V1del - it is clear now. Perhaps this thread will also help any others who come across the same issue.
