[SOLVED] Sound works fine, be concerned I have no PCM?

Here is my output from the amixer command: also how do I get it so alsa stores the sound levels?  I followed the wiki but nothing, the Front mixer still stays at zero which are my external speakers.

With alsactl you can store your sound level:

alsactl [options] [store|restore|init] <card # or id or device>

You must run the alsa daemon to restore your sound level.

If you're missing PCM control then you'll probably need to add the modules in /etc/rc.conf, atleast thats what worked for me when I reinstalled.

For the record, I can control PCM through alsamixer without snd_pcm in the rc.conf MODULES array...

Re: [SOLVED] Sound works fine, be concerned I have no PCM?

Maybe because I have external logitech speakers, that prob. have their own Preamp.  What order do I put alsa in the rc.conf DAEMONS section?  , after fam, before network? in the beginning or end?  Thanks for all the help guys

I put it at the end as such:

DAEMONS=(hal network cups @alsa)
