Sound errors in mandrake 10 - c-media 8738 onboard card
 

I have just installed mandrake 10 only to find that my sound card refuses to work. I have an onboard c-media 8738 soundcard which linux picks up, but it will not play sound through it

Every time something tries to access the sound server, an error message comes up saying "error finding /dev/dsp (file does not exist)"

I think that the sound device is somewhere different to where the module says it is, meaning I could force the sound server to look somewhere else, but i don't know where that would be.

Run harddrake2 in X, and check your card section.. It should provide 2 buttons on lower left Run Config Tool and Configure module... One of them letz you choose the kernel driver (as I recall it's snd-cmipci8738, or just cmipci8738). If that doesn't help, check this out http://www.linuxquestions.org/questi...hreadid=199167... same problem... You should give it a try with the alsaconf.

yeah theres :

cmipci - for OSS

snd-cmipci - for alsa

Both drivers result in the same error message

I tried alsaconfig, and the card was picked up and installed with no errors, but then on running alsamixer, the following error comes up:

"alsamixer: function snd_ctl_open failed for default: No such device"

Try a lsmod and see wether the kernel mdoule you chose is listed there... if not, do a manual modprobe snd-cmipci. I belive snd-cmipci is for the pci version, duuno 4 sure. You said yours is onboard and the module might not see it in the right place. Look for some drivers on the net (maybe on the motherboard CD?)

since it's onboard sound, you might need to run sndconfig. in a terminal as root type sndconfig (hit enter). let it search for your sound device. when it's found, select it, ok it, let it install the necessary drivers, test the sound.

otis

Should'nt it had been found by the alsaconf?

rite

ive got the folloving sound plugins(sorry bout the layout, i just copied it straight from konsole)

my device is in that list, so i dont see why it shouldnt work...

i dont seem to have sndconfig on my system! so i cant use that :P

use MCC->software installer to install sndconfig, or in terminal as root type urpmi sndconfig (hit enter).

otis

i found sndconfig and installed the package.

it picks up the card, but it is unrecognised, so it wont install drivers for it.

Search some drivers on Google if you can't find any LInux drivers on the motherboard install CD. My CMedia 8738 PCI came with an Install CD that contained those drivers :)

right

ive just dug out my mobo cd, there are drivers here, ill try them out. be back soon!

ok then, the only difference now is that i also have a cmpci driver, which doesnt work...

sorry about 2 replies in a row, but I just thought of something!

Would the 2.4 kernel sound drivers work? because I used to be on redhat 9 where this soundcard was picked up straight away. If these sound drivers would work, and someone has them, can you PM me about them?

Thanks

/dev/dsp should be a hyperlink to /dev/dsp0. Open XMMS, go to config and select the OSS sound module at the Output device. Configure it and choose alternate device. In the box, type /dev/dsp0. If this doesn't work, do a ls -lah /dev/ds* and see what comes up. try all the /dev/dspX listed by ls.

I have no dsp devices at all in my /dev folder.

I also figured out why my mainboard drivers didnt work - the kernel came up with an error before when i tried to install the sound modules, I just didnt see it!

Apparently, my sound drivers are using deprecated headings, I think its to do with a new kernel.

Have you got your 8738 working on 2.6 eqxro?
