Laptop Sound Issues

Round 3 for me...

Anyway, after troubleshooting and troubleshooting sound problems with my sony laptop, I've decided to try to find newer drivers. The problem is, how do I go about doing this? lspci -v prints out:

Code:

00:1f.5 Multimedia audio controller: Intel Corp. 82801CA/CAM AC'97 Audio Controller (rev 02)
        Subsystem: Sony Corporation: Unknown device 80fa

lsmod prints out:

As I said before, the sound is choppy and unrecognizable. Running Slackware 10.0, w/KDE 3.3.2

Have you tried using ALSA? That's always worked for me, of course, I've never had to deal with a Sony Vaio laptop,

If you boot the machine with pcmcia disabled, do you still have the choppy sound?

Hrm, I know there is a /etc/pcmcia directory, but how would I go about disabling it?

You can use the update-rc.d command (see manpage for more info), or you can manually change the link in your default runlevel, typically /etc/rc2.d/S20pcmcia (or similar), to K20pcmcia temporarily.

I renamed rc.pcmcia and still no improvement.

The reason I asked about pcmcia, is that I've had issues on a couple of older Dell and HP laptops where the effect was what you described. The effect wasn't present when pcmcia was shut off. Turns out, the pcmcia system was trying to use one of the same resources as the builtin sound card (Crystal 423x chipset), so I had to change /etc/pcmcia/config.opts file and edit some of the "include port xxx" lines so that it used different ports. I don't have any experience with the Sony machines, so I can't really tell you any more.

and see if your model is listed, you'd be able to get working configs and such and more detailed install info.
