Description Rodd Clarkson 2008-05-06 10:37:19 UTC
Description of problem:

Each time I start f9-preview, just before the [OK] appears for Starting UDev, I
hear a reasonably loud, audible POP from my speakers.

This didn't happen in f8 and while it doesn't seem to do any damage, I can't
imagine why my speakers need to POP on start up.

Is this an issue? And what more do you need to know?

Version-Release number of selected component (if applicable):


How reproducible:

Very reproducible.  Just (re)boot fedora.

Comment 1 Harald Hoyer 2008-05-06 10:45:02 UTC
My guess:

sound modules get loaded

/etc/udev/rules.d/90-alsa.rules runs /sbin/salsa, which restores the last mixer

mixer settings are stored in /etc/alsa/asound.state

$ fgrep salsa  /etc/init.d/*
/etc/init.d/halt:if [ $? = 0 -a -x /sbin/salsa ]; then
/etc/init.d/halt:   action $"Saving mixer settings" /sbin/salsa -s

and this is stored if you shut down your system.

not a udev bug...
