 |

I jus upgraded to 2005.1, and now sound doesn't work. I'm running the same kernel as before, 2.6.10 with the ALSA and card (intel8x0) drivers compiled into it. alsaplayer works, but gives me the following anyway:
| Quote: | ALSA lib confmisc.c:550:(snd_determine_driver) could not open control for card 0ALSA lib conf.c:3463:(_snd_config_evaluate) function snd_func_card_driver returned error: Permission denied

xmms comes up with its window all garbled (more so than usual, I mean), and trying to play an mp3 results in:
| Quote: | ALSA lib confmisc.c:550:(snd_determine_driver) could not open control for card 0
ALSA lib conf.c:3463:(_snd_config_evaluate) function snd_func_card_driver returned error: Permission denied

** WARNING **: alsa_setup(): Failed to open pcm device (default): Permission denied

So, obviously I have a permissions problem somewhere, but I've no clue where.

I don't know if this would help, but, open up /etc/security/console.perms as root and edit the line:
<console> 0600 <sound> 0600 root.audio
to
<console> 0660 <sound> 0660 root.audio
For future reference, you have 2005.0. 2005.1 has not been released yet. |

Fixed it. I needed to set the permissions on the alsa devices via udev. I added myself to the audio group and added GROUP="audio" to the lines in /etc/udev/rules.d/50-udev.rules, as follows:
| Quote: |
# alsa devices
SUBSYSTEM="sound", GROUP="audio"
KERNEL="controlC[0-9]*", NAME="snd/%k", GROUP="audio"
KERNEL="hw[CD0-9]*", NAME="snd/%k", GROUP="audio"
KERNEL="pcm[CD0-9cp]*", NAME="snd/%k", GROUP="audio"
KERNEL="midiC[D0-9]*", NAME="snd/%k", GROUP="audio"
KERNEL="timer", NAME="snd/%k", GROUP="audio"
KERNEL="seq", NAME="snd/%k", GROUP="audio"
