Re: sound driver for Dell Latitude CP (and other laptops)

[Derrick J Brashear <shadow@DEMENTIA.ORG>]

I have a Dell Latitude CPi; Based on what you said I assume the audio is
the same. I'm ucrrently using ALSA with the following configuration:
add to /etc/conf.modules:
alias char-major-14 snd
alias snd-minor-oss-0 snd-card-cs4232
alias snd-minor-oss-3 snd-pcm1-oss
alias snd-minor-oss-4 snd-pcm1-oss
alias snd-minor-oss-5 snd-pcm1-oss
alias snd-minor-oss-12 snd-pcm1-oss
alias snd-card-0 snd-card-cs4232
options snd snd_major\x14 snd_cards_limit=1
options snd-card-cs4232 snd_index=1 snd_port=0x530 snd_irq=5 snd_dma1=1 snd_dma2=0

Then:
modprobe snd-card-0

Then go; You will need to unmute the sound card before you can use it; 
cat /proc/asound/0/mixer0 | sed s/mute// > /proc/asound/0/mixer0

Note that I needed to configure e.g. the parallel port from within windows
to be not ECPP or something like that; Basically, if Windows can do duplex
audio, this will work, otherwise there are 3 things you must pick from,
which are ECPP, duplex audio, and something else, and I don't remember how
I discovered what was what.
