Description Thibaut FRANCOIS 2011-10-08 15:27:23 CEST

Description of problem: For few weeks, I have no sound


Version-Release number of selected component (if applicable):
all package up to date
kernel 3.1.0-desktop-0.rc9.1.mga2

Same symptoms as bug 2899 (https://bugs.mageia.org/show_bug.cgi?id=2899) but the results of the commands are different for me:

colin something for you ? :)

/me must really learn how to debug sound. :p

Comment 3 Thibaut FRANCOIS 2011-10-09 12:22:24 CEST

To give some informations to my problem :
in the pulseaudio miser, I have only a "dummy output", and in the setup section "no card available"

Comment 4 Colin Guthrie 2011-10-10 10:00:01 CEST

This looks like fallout from systemd migration again (this has been reported several times on the Cauldron mailing list).

Basically there are no ACLs on your sound device nodes (/dev/snd/pcm*) and as such your user cannot access them and as a further extension PA gives you a dummy output instead.

The output from "systemd-loginctl" will likely NOT

Comment 5 Colin Guthrie 2011-10-10 10:02:10 CEST

Damn, pressed <tab>-<return> as a typo and that submitted the bug :D

The output from "systemd-loginctl" will likely NOT show your user as being logged in.

Check in /etc/pam.d/ for .rpmnew files, particularly the system-auth and gdm files. Consolidate the additions in system-auth.rpmnew into the system-auth file and then reboot. Your user should show up under systemd-loginctl and also have ACLs on the sound nodes.

I'll close the bug just now as I'm pretty confident this is the issue.

Feel free to reopen if I'm wrong tho' :)

Status: NEW => RESOLVED
Resolution: (none) => WORKSFORME

Comment 6 Thibaut FRANCOIS 2011-10-11 08:25:40 CEST

Yeah, I rename system-auth.rpmnew with system-auth and after reboot, the sound is here !

Thanks a lot Colin ! :)
