Hi, I ran pacman -Syu just now after a gap of almost 3 weeks. After the update I restarted my system and now I can't play audio. Even mpd doesn't start up. alsamixer shows Card: PulseAudio and Chip:PulseAudio. Please help me as I can't do work on my computer with listening to music. :( I have pulseaudio installed just because gdm needs it. Other than that I use alsa.

What does your mpd log in /var/log/mpd/mpd.log say?

The last entry in mpd.log is from 02 oct. I doubt that will help. However when I try to start mpd I get this error, [papul@archlinux ~]$ sudo rc.d start mpd :: Starting Music Player Daemon [BUSY] /etc/rc.d/mpd: line 6: 9910 Aborted /usr/bin/mpd /etc/mpd.conf &>/dev/null

Usually I put in hashes ('#') into the /etc/rc.d/mpd script to check what output there is destroyed. Could be useful. cheers! mar77i

Where do I put the '#' in the /etc/rc.d/mpd script? In the beginning or in a specific line?

wow that fails for several reasons. you should: 1. configure alsa in mpd.conf, then mpd will be mixed over dmix (which won't fix the actual problem) 2. make sure the user which runs mpd to the audio group and figure out why both alsa and pulse would refuse the connection. who (uid/gid) runs those, what other security mechanisms could stick in between, like a too restrictively configured firewall etc. oh and you should figure out if mpd is already running, or if this config option is plain wrong that makes mpd try to "bind to '0.0.0.0:6600' failed: Address already in use" ... sometimes mpd hangs up and you have to kill it with SIGABRT / 6. I'm just at a very similar issue a friend of mine is having with mpd and jack. you should get those permissions right in the first place... :) I'll go there and adjust /etc/group until it works, I guess. cheers! mar77i

Forget about mpd. Why doesn't audio play on vlc and in browsers? I regularly visit sites like grooveshark,com. Also I do have my username in audio group. Everything was fine until I ran pacman -Syu. :(
