Re: [SLE] Sound Card Still Squealing Away [still no joy]
I still can't get the soundcard to quick squealing/buzzing under suse 9.2. I'm running out of things to try. Anybody have any other thoughts? Details below:






From: "David Chapman" <linux-lists@xxxxxxxxxxxx>

Have you tried alsaconf from the command line rather than using yast.
And or turn down PCM in Kmix

Yes, I've tried alsaconf, I've stopped alsa, I've turned down and muted PCM
to no avail. What is strange is that the squeal gets turned on early in the
boot process - very early and doesn't stop until the system shuts down. It
appears interrupt related because when you type, or move windows around,
etc. the squeal stops briefly while other input is processed. There is no
squeal what so ever when I boot into XP. How do I check to see if it is
kernel related, driver related, etc......


Mates,

The problem is my nForce AC97 Audio Controller on my K7N2 Delta
motherboard is squealing in my ears. It's enough to drive you nuts.........
The problem is more serious than I thought. I can stop alsasound and it
still keeps squealing. I can mute everything in kmix -- same result. I can
be in runlevel 3 and it still squeals. It gets better when sound is
playing, but then goes back to squealing when the file is done. YaST has
even got buggyirq configured. I have googled and RTFM and still no luck.
What is weird is that since this is a dual boot machine, I can confirm that
there is not problem at all like this with XP. It has to be kernel or
interrupt related. Has anybody else 'heard' about this issue?? (no pun
intended) I can hold down the cursor keys and scroll through text and the
squeal gets more choppy (i.e. goes away when the key strokes are processed)
Literally, my computer sounds like it is generating Morse code as I type.
Here are some additional details on my config.
