Sound problem with Slackware 11.0
I would appreciate a little advice on getting my sound card working with my new Slack 11 installation. It was a clean install with kernel, and I am trying to use my C-Media 8738/C3DX card. My machine also has onboard sound which seems to be the problem. Here is the output of lsmod | grep > snd:
snd-seq-oss 23104 0 (unused)

alsaconf configures the c-media card but sees the onboard via chip. alsamixer sets volumes only for the via chip. Any ideas?

When you boot up, see if you get an error? I have the same card, and I get an error saying I need to load the alsa module, or something like that. I have not got it fixed yet, because I am working on other things first. But you may not have the modules loaded.

It might be easiest to disable the onboard sound via cmos setup. Otherwise you will need to specify whcih card is which card number. I do this because I currently have 2 sound cards and made a /etc/modprobe.d/sound file for this purpose:


alias snd-card-0 snd-emu10k1
alias sound-slot-0 snd-emu10k1
alias snd-card-1 snd-ens1371
alias sound-slot-1 snd-ens1371
options snd-emu10k1 index=0
options snd-ens1371 index=1

many thanks
Disabling the on-board sound in BIOS worked like a charm. The output is still a bit quirky, but I'll check the book on the card for that. Thanks!
