nvidia + sound on laptop

[Pooh]

Hi

 

I'm having a lot of trouble getting my laptop to do nvidia XFree86 (+ twinview) and sound. This is not working since I tried installing mandrake 9.1 on the thing...

 

To give you an idea of the hardware I'm working on, see http://margo.student.utwente.nl/simon/ongo...ng/jade8060.php. Strangely enough, I had everything working with mandrake 9.0 + kde 3.1 and kernel 2.4.21-pre4-ac4. I'm not sure anymore if alsa was very important in this, but I had that configured as well at some point.

 

I tried the pre4-ac4 kernel with mdk-9.1, other kernels (rc1/2/3), nvidia 4191 and 4363. The latter nvidia driver simply disabled both console and X, so I tried 4191, which works fine, but no sound.

 

Desperate I went back to mandrake 9.0 (clean install, updates, kde3.1). tried the same stuff, pre4-ac4, rc6 and rc6 with laptop patches https://savannah.nongnu.org/projects/laptopkernel/ same problem :-( Sound (ac97/i810) is working fine until I start X, then it says /dev/dsp is busy and this doesn't auto-repair when you kill X.

 

Somehow mandrake doesn't make it easy to switch drivers (kernel/alsa/oss) for devices and I haven't figured how to do this yet (use alsa instead of kernel driver), except by going to read a lot of documentation and I'm not even sure if this is the real problem.

 

 

I don't really know what to do now, both mandrake 9.0 and 9.1 don't work anymore (including the features I want working). nVidia seems to be the problem, but I need that driver to view stuff on my TV. Any tips?

 

Cheers

By not allowing arts to grab the sound device (playing sound while kde is starting up), I was able to keep the use of /dev/dsp possible, so it might be unrelated to nvidia (except that I didn't have the problem with the nv driver.
