How do you know?
If you have written down any sound configuration details from previous working setups [windoze/linux] - now would be a time to say, as dma/ports/irq are all details which, if wrong/missing, can prevent sound from working
I posted already that there are at least 2 different sound chips for dell latitude as well as different latitude models
could be CS4236, or CS4237B...... AFAIK, maybe others also
Have you tried alsa wizard 'try legacy probe'??
result??
1st I believe from tempestuous's posts, the code to find out [type in console] is:
Code:
lsmod
post resultant snd ID
2nd the link you give says try modprobe - do this in a console
start with trying
Code:
modprobe -r snd-card-cs4236
in case there is any loaded code/card info [removes it]
then try
Code:
modprobe snd-card-cs4236 snd_port=0x534 snd_cport=0x120
if that then gets a sound card found
try
Code:
modprobe snd-card-cs4236 snd_port=0x534
snd_cport=0x120 snd_mpu_port=-1 snd_fm_port=0x388 snd_jport=-1
snd_irq=5 snd_dma1=0 snd_dma2=1
If it doesn't, replace CS4236 with CS4237B, and run it all again, from 'start with trying' line
If either is successful after doing this, run alsamixer and check that volume is not muted, as I've seen many 'no sound' posts fixed by un-muting volume - see volume control bottom right/red cross if muted, just bring volume up to unmute, I believe
HTH
This should really be in the thread, so if you post there, I'll copy my reply for other's benefit
