[linux-laptop] ALSA and DVD play problems

I might offer some help with the audio problem.  I think you said you
got sound OK? I hope so.  When you get your levels where you want them
and have decided which controls you want captured, muted, etc., then use
the command 'alsactl store' to save the settings.  By default, the
settings will be saved in a file called asound.state (I think).  Then
each time the machine is booted, you need to run the command 'alsactl
restore' to restore the settings.  This of course, can be added to a
start up script.  Slackware provides this in a file called rc.alsa but I
believe you were running Fedora and I don't know how they specifically
do it.

HTH.

I haven't used a computer in a while though, and my last kernel wsa 2.4.16, so my new Debian 3.0r1 sarge install with a custom 2.6.12.4 kernel is somewhat new to me.  I have two problems, one with ALSA, and the other with playing DVDs.  I have a Dell Inspiron 6000 with a ATI Radeon MObility x300 (using firegl driver on x.org), intel ac97 (using snd_intel_8x0 and snd_ac97_codec), and a DVD+-RW drive listed at /dev/dvd.

However, no sound is set up at all, and when xmms or any other audio program gets action, it appears to be playing, but no sound...until I run alsaconf, and set up the driver again.  Then everything is peachy.  However, it gets old having to run that on every boot.  Is there a way that I can set it up (maybe in rc.d) so that it does it all automatically?

I used to have mplayer on my old system, and I love it, and now there's apparently a good gui as well (which I also can't get to compile, because I use x.org from a hoary hedgehog apt source and the libraries do some wierd version mismatches so they won't download required libraries...I'll fudge with that later...)  However, I got apt-get install xine-ui, and this is the output for that while playing the "Sin City" DVD:

Run as root, I see the green FBI warning for a split second, then the screen goes all scrambled, and sometimes I can Ctrl+Alt+Backspace and restart X, and sometimes it's a hard lock.  BLAST!  I have support for framebuffer devices in my kernel builtin, so I don't know why it can't open /dev/fb0.  However, no -vo setting seems to work at all.  I have libdvdread, libdvdplay, and just about every other freakin' library.  I put the codecs from mplayer into the corresponding codec directory.  I don't know why it has to be so stupid.
