Sound card problem on laptop.

xern

Hi,

i have just put mandrake 10 on my laptop. everything works fine but the sound card. it has picked it up alright but nothing seem to happen! the laptop is a clevo d27es.
it has a sis 7012 sound card. it has been given the proper driver as fare as i can see.
it hasn't picked up the modem either but thats a battle for another day!!!

Below is the output of some the commands i used from the documentation. any help would be great.


[mike@localhost mike]$ lspcidrake -v |fgrep AUDIO

Sounds silly I know, but try opening the sound mixer and upping the volume. This seems to happen a lot with Mandrake on install.

xern

no joy. i can open the mixer alright but nothing happens. the sound icon is there but there is an X over it!!

thanks for your reply.

Typedef

I'm sure I posted this on ILUG.


chmod 777 /dev/sound*
chmod 777 /dev/snd*

Then try the mixer.

xern

Thanks for that typedf.

Yeah got that on Ilug but still no joy.
i can open up the mixer but there is nothing on it.
i have the volume up to the last on the laptop aswell.
It even has a guy i work with here confused, and i would class him as a linux guru type.

when i try to play mp3's on xmms i get these errors on the command line.

[mike@localhost mike]$ xmms &
[1] 2260
[mike@localhost mike]$
** WARNING **: alsa_get_mixer(): Attaching to mixer hw:0 failed: No such device

** WARNING **: alsa_setup(): Failed to open pcm device (default): No such device

Typedef

What that means is that xmms is trying to find an oss compliant mixer device and is failing.


These two modules *should* be providing that

snd-pcm-oss
snd-mixer-oss


Personally I don't like ALSA, because I think the setup requirements it imposes on the user are reterograde in comparison to the old oss layer.

In any case it's quite likely that the oss drivers are also bundled with your distro, so as root.

/etc/init.d/alsa stop

Ensure there are no stale sound drivers hanging around.

Then modprobe for the intel 8x driver in lib/modules/version/kernel/drivers/sound/oss as opposed to the alsa version.

Typedef

Actually, I think those modules *are* providing the pcm and mixer.

Try chmod 777 /dev/mixer* && chmod 777 /dev/pcm*

Assuming the two modules I posted above are doing their jobs, that should be all you need to do.

Else, use the oss driver.
