Hello,
Search on linux sound in the Thinkpad archives. I think I posted
some info in the past.
I have a 600e. You cannot use the sound configuration utility
with the 600e because it will configure for an unsupported Crystal 4610.
You need to manually configure modules.conf for a Crystal 4236.
Make sure quick boot is off in the ez-setup and that audio is
enabled. I use SuSE 8.0 on my 600e. SuSE 7.3 had a nice example
configuration for the laptop using OSS. Others may be similar.
See the documentation for the sound driver that handles a
Crystal 4236.
# some of the OSS aliases for sound
alias sound-slot-0 snd-card-0
alias sound-card-0 snd-cs4236
# The following 2 lines are on a single line in the file
options snd-cs4236 snd_index=0 snd_port=0x530 snd_cport=0x538
snd_irq=5 snd_dma1=1 snd_dma2=0 snd_isapnp=0
Basically you need to manually configure the sound settings.
The ones above are typical (sometimes you need to swap the
two dma settings [snd_dma1=0 snd_dma2=1]). You need to use
a program, like ps2.exe, to find out the bootup settings of
the audio chip (Windows can change things).

Hi Pete,
Thanks for the email. I made the changes to modules.conf and did the depmod
-a, per your suggestion, and now it seems the laptop tries to play a file
but
no output (sound). Here is what I found in my dmesg:
I need a codec? I have no idea what will fix this. At least it sees my
sound
support but no audio.. :(
Any ideas???? please help
