Package: alsa-base Version: 1.0.16-1 Severity: normal
This bug seems related to #446968, but that bug seems mired in mac-powerpc-specific device driver issues, whereas I am running an Intel-based PC. About once or twice a week, sound stops working on my system. Well, that's not exactly accurate; sound stops working for new logins; if an old login is open when the problem starts, sound for this session will usually (though not always) keep working. This computer serves the whole family, and we use virtual consoles so there are up to four sessions open at one time (none remote). As reported in #446968, whenever this happens, applications which try to use sound tend to hang; most annoyingly, flash hangs the whole browser (of course, this is out of scope of this bug). On my system, there doesn't seem to be an "/etc/init.d/alsa" as mentioned in #446968; after reading other bugs, I've tried "/etc/init.d/alsa-utils reset" and "/etc/init.d/acpid restart", to no avail; a reboot does solve the problem, so I guess I just need to find out what it is that I need to restart. I hope it doesn't turn out to be the kernel...

Lines beginning with "#" are ignored. loop sbp2 We're all using KDE & arts, so maybe some of the problem is there; next time this happens, I'll see if a new gnome session gets sound. But I'm skeptic.
