Hello,

I have questions regarding the mixer settings of the alsa sound package:

1. After installing the latest alsa drivers, I unmuted all channels (I
tried amixer and alsamixer) and set the desired volume for them. After
rebooting the computer, all channels were muted again and their volume
was set to zero. How can I prevent the settings from being reset after a
reboot?

2. I want to prevent normal users from changing the mixer settings. Do
alsamixer and amixer store the settings somewhere on disk so that a user
can change settings by editing a file (so that I have to set the correct
access rights so that it cannot be changed by normal users). or is it
sufficient to give execution rights for amixer and alsamixer only to
root? Are there any programs other than amixer and alsamixer that can be
used to change the mixer settings?

Christoph
