aye. try modprobe instead of insmod

alsa driver w/ C-Media CM8738 sound chip

Hi,

	Anyone got any suggestions on this problem? Apologies to those who have slow connections, or have to pay for downloading everything (I've attached a couple of the key fiiles).

	C-Media CM8738 sound chip on the main board of this system. Both alsa 0.5.11 and 0.9.0beta4 give the same results:

	After installing the driver, lib and utils (in that order), I do 'depmod -a', then 'insmod snd-card-cmipci'.

	I'm attaching my alsa file from /etc/modutils which gets put into /etc/modules, and the file which contains the output when I do the insmod, showing the 'unresolved symbols'.

	Am I missing something, or is the driver for this sound chip not working? Any suggestions/pointers are most appreciated.

Hi,

	Thanks for the suggestion! Modprobe (I'd already tried) gives no errors, but fails to load thhe module. Additionally, 'modprobe -v' gives no errors

Re: alsa driver w/ C-Media CM8738 sound chip

[Gregory Nowak]

I had something similar to your problem with kernel 2.4.2 and alsa 0.5.10.
In my case, everything went fine, but the /dev/dsp device could not be accessed by anything.
So, I got the version of the ossfree driver that supports the modem function from
cmedia's sight, switched to kernel 2.2.18 since that driver wouldn't compile for 2.4.2, and use that instead.
