Have been updating scripts to tidy up after a change to Baselayout2 on a machine that hadn't synced for something like 256 days, now running through dispatch-conf, and am being advised that:

Code:

--- /etc/conf.d/alsasound       2012-01-17 16:05:00.000000000 +1000
+++ /etc/conf.d/._cfg0000_alsasound     2012-01-18 13:06:16.000000000 +1000
@@ -13,7 +13,7 @@
 
 RESTORE_ON_START="yes"
 
-SAVE_ON_STOP="yes"
+# SAVE_ON_STOP:
 # Do you want to save changes made to your mixer volumes when alsasound
 # stops?
 # no - Do not save state


Which looks to me like it's not going to save my settings on reboot. Is this now the default condition or should I re-insert the SAVE_ON_STOP command in the script to retain my settings between sessions?

Sorry if this has been covered previously, but I recall I had problems with sound defaults on this machine when I built it a year ago, and I'd rather avoid them this time around.[/code]

Hi,
what I do first is to save manually the mixer settings I set with the command alsactl . Then I set /etc/conf.d/alsasound with
Code:
SAVE_ON_STOP="no"
RESTORE_ON_START="yes"

That way, no matter the mixer changes I made during the session, the channels will be restored like I did manually at boot time.

The problem with saving asound.state is that ALSA sometimes rearranges the mixers, between ALSA versions. So the asound.state file becomes invalid.

To workaround that, I just run amixer commands in a startup script.
