I'd like to report a rather unexpected behavior that was a bit undocumented in the (generally remarkable and excellent) Arch Wiki.
Situation is in my system:
Arch + systemd + LXDE (lxsession + openbox) (X autostarts)
NO pulseaudio (only libpulse installed), NO oss (in kernel modules), only ALSA for audio
LXDM user switching is used (/usr/sbin/lxdm -c USER_SWITCH)
Two users are active (both members of group 'users' primarily)
NO user is member of group 'audio'
With the above configuration, only the first user (any of the two) logged in X has audio. The second one cannot even access alsamixer, and all sound-dependent functionalities fail.
The situation is corrected fully if both accounts become members of the 'audio' group with:
usermod -a -G audio <user>Note: I have never tried to make pulseaudio work...
Hardware is: laptop Toshiba U300-13J 2GB RAM
Output of lspci, lsmod, and pacman is linked (last pacman -Syu May-10 2013 -- today)
I just have the feeling that this behavior should be easily reproducible with any hardware that has similar configuration, and might have a place in the X user switching wiki sections (LXDM setup, or references to 'audio' group not supposed to be used...)
I would like to understand whether I am correctly using the 'audio' group for this situation, or there's another proper way to make this work.
Thanks!
