You have to set the volumes once, then as root do :
You have to run alsactl restore sometime during boot, one way is to have it run as soon as you load the modules. You can also tell alsactl to store the volumes when the modules are unloaded, so that the volume will always be like they were the last time you shut down your computer.
My example uses the snd-emu10k1 module, as I have a sblive card. Replace this with the name of your module. Which you can find in your /etc/modprobe.conf. But I'm sure you know this, you are using a test release after all.
Add this to /etc/modprobe.conf
Code:
install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-emu10k1 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-emu10k1
This should be in there already, I don't know why it isn't, as a tester it is your responsiblity to investigate and report issues like this.
