Random sound problem on Latitude D600

Random sound problem on Latitude D600

I'm having wierd, random problem with sound on my Dell Latitude D600.
Everyonce in a while, I get the following error after logging in to KDE:

Sound server informational message:
Error while initializing the sound driver:
can't set requested samplingrate (requested rate 44100, got rate 11906)
The sound server will continue, using the null output device.

Now, I've noticed this only happens when I'm not on AC power, but not
all the times. Often, if I reboot after getting this message, it comes
back up fine.

I'm using the 2.4.22 kernel with the ac4 patch on RH9. I compiled in
all the ACPI support. Here's the output from dmesg:

.....
Intel 810 + AC97 Audio, version 0.24, 09:12:48 Oct 26 2003
PCI: Setting latency timer of device 00:1f.5 to 64

i810_audio: Primary codec has ID 0

ac97_codec: AC97 Audio codec, id: 0x8384:0x7650 (Unknown)
i810_audio: AC'97 codec 0 supports AMAP, total channels = 2
....

dmesg reports the same thing when the sound works as when it doesn't
work. Anyone have any ideas?

Try our commercial OSS drivers - a free trial version is at http://www.yqcomputer.com/
and it should have no problems. However we would be interested in noting if our drivers fail
the same way - it's usually something to do with ACPI bios - disable ACPI bios while booting and
perhaps it may work.

What do you think this is, a free adverti *** t medium? People here are
in it for the love of technology, not money. If I wanted your
commercial OSS driver, I would have posted: "Does anyone know of a good
commercial OSS driver, because my sound card isn't working and I know
that someone's proprietary *** will fix it." Making my sound work
isn't the point. Getting into linux and learning how to hack things out
is. So if you have any suggestions on the ACPI bug that is causing this
problem, I'd love to hear it. Otherwise, take your adverti *** t
publish it in Linux Journal, I'd love to read it there.

Alright, point well taken. We wanted to just alert you to the fact that commercial
drivers exist. Maybe some people don't know about OSS.

The actual solution to your problem maybe to check KDE's artsd and set the
server sampling rate to 48000. Now restart X (or logout and log back in) and
see if you still have problems.

The fact that you are getting audio, implies that the OSS/Free drivers are working
fine. If ACPI was an issue you won't be getting interrupts.

And FYI, we're not only about commercial proprietary crap. You should take a look
at the copyrights for XMMS sometime (heck go to www.xmms.org)!


Best regards

My appologies for being so rude, but I think you understand. Thank you
for the suggestions. I will give it a try.
