Details

Description: For a few days now (I'm not sure since which update) I have troubles with sound. It works fine in KDE (welcoming sound, Koppete incoming message, alert sounds, etc.), amaroK and JuK play OK as well but it doesn't work anywhere else: mplayer, vlc, totem, dragon player or Flash inside web browsers.

Most of them show no error messages at all, only vlc says this:
VLC media player 2.0.5 Twoflower (revision 2.0.5-0-g1661b7d)
[0xd80048] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
[0x7fce3c0012f8] pulse audio output error: PulseAudio server connection failure: Connection refused

I'm not sure if it's definitely pulse audio related but in case it is, this is the output of pacman -Qs pulse:
local/libao 1.1.0-3
Cross-platform audio output library and plugins
local/libcanberra-pulse 0.30-3
PulseAudio plugin for libcanberra
local/libpulse 3.0-2
A featureful, general-purpose sound server (client library)
This task depends upon

I think I had that same problem too. It appeared with linux 3.7.x. Seems there have been some changes in the audio department. You might want to check with alsamixer if all audio channels are turned on. In my case the PCM channel was at zero and some apps seem to use that one. Tuning it to 100 fixed it.

I have meanwhile "solved" this problem by installing pulseaudio and pulseaudio-alsa. After that the situation was reversed: all non-KDE applications "played" well and there was no sound in KDE. But luckily I was then able to fiddle with some KDE settings and make it work everywhere.
Still, thanks for the suggestion, I don't remember if my PCM channel was on, I might try to reverse the situation and try it without pulseaudio.
