Bug 186066 – ALSA only works as root with sys-fs/udev-113

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Petter Häggholm 2007-07-21 05:37:47 UTC]

As above: When I try to playback sound (or fire up the GNOME mixer, or...), I get error messages, unless as root. Downgrading to sys-fs/udev-112-r1 fixed the problem. 

Reproducible: Always

Steps to Reproduce:
1. Try to play some sound
Actual Results:  
Error messages of various descriptions

Expected Results:  
Play some sound

Representative error message, from mplayer:

Mis-identified the problem. Downgrading didn't fix the problem -- running udevstart did. (udev-112 also didn't work on boot -- until running udevstart.) More later, if I figure it out.
