I have an all SCSI system - RAID 5 array on an Adaptec 3210S controller. The DVR/CDRW and DVD units are IDE. As root I can run alsaplayer with no problem. As a user I got the error "access to /dev/cdrom denied" unless I added my user to the disk group or modified the /etc/udev/permission.d/50-udev.permissions to have group cdrom for the device hd*. In addition I get an error below right after login unless I run udevstart. snd_pcm_open: Permission denied (default) Failed to initialize plugin! Failed to register plugin: /usr/lib/alsaplayer/output/libalsa_out.so Failed to load output plugin "alsa". Trying defaults. snd_pcm_open: Permission denied (default) Failed to initialize plugin! /usr/lib/alsaplayer/output/libalsa_out.so failed to load jack: server not running? /usr/lib/alsaplayer/output/libjack_out.so failed to load error opening /dev/dsp Failed to initialize plugin! /usr/lib/alsaplayer/output/liboss_out.so failed to load No $AUDIOSERVER, falling back on $DISPLAY NAS server not available Failed to initialize plugin! /usr/lib/alsaplayer/output/libnas_out.so failed to load NOTE: THIS IS THE NULL PLUGIN. YOU WILL NOT HEAR SOUND!! I've read the docs, tried various permissions, etc. still have the problem. Any information you need I'd be glad to provide. If it's something I'm doing I can't find it nor have others on the user mail list been able to help. I'm running development-sources 2.6.7.
Update - I was using development-sources (when I went through the kernel guide I thought it was vanilla with Gentoo patches). I switched to gentoo-dev-sources and now alsaplayer works without being a member of the disk group.
gentoo-dev sources doesn't touch alsa, though...
No, it doesn't but all I did was move from development-sources to gentoo-dev-sources and now it works without being a memeber of the disk group. Maybe development-sources has a problem or udev with dev sources? I don't know but I know the problem does exist with development-sources as I spent a lot of time trying to work around it.
