[ale] ThinkPad sound working

[James Taylor]

 Bob - I had responded this before, but it looks like the list is not
posting my emails.

I had a problem with DVD speed on my Thinkpad, and other PCs, until I
enabled DMA on the DVD player.  Up until the latest release of SUSE,
which I us, it disabled DMA on CD/DVDs by default.  It may not have any
bearing on your issue, but if you haven't checked it, it's worth a
look.

THANKS for that.  That tells me that it should work well once I verify
that I'm doing DMA and have tweaked X.

I'll have to set this up.  I've not needed fast graphics before.

You know me!  It is Slackware and I don't want to change unless I
absolutely
have no choice but DVD movies have become important to me.  I'll
report
back to ALE when I have resolved this.

Thanks.

Compiling X?  Now that's scary.

Thanks.
