[Pkg-alsa-devel] Bug#516701: No sound on Thinkpad 600E

[Abu Yoav]

Package: alsa-base
Version: 1.0.17.dfsg-4

I've installed Debian 5.0 on my Thinkpad 600E. Sound did not work.
However, I've found a workaround on the net. What follows is
essentially a synopsis of
http://www.wlug.org.nz/ThinkpadNotes

0) As a preliminary step, you have to disable the "Quick Boot" option
in the bios (since we will not be using plug-and-play). To do this,
press F1 on boot. Then,
Config->Quick Boot->Disable

1) Now, we have to disable plug-and-play and acpi on boot. So, in
/boot/grub/menu.lst
append
pnpbios=off acpi=off
to the line that starts with
# kopt=
Then, run grub-update

2) We now need to load the sound card "manually". Append
snd-cs4236
to
/etc/modules
Note: after running lspci we get
00:06.0 Multimedia audio controller: Cirrus Logic CS 4610/11
[CrystalClear SoundFusion Audio Accelerator] (rev 01)
But, we use cs4236 and NOT cs4610 or whatever

3) We now give the loading options. So, create (or edit if exists)
/etc/modprobe.d/sound
and write in it
options snd-cs4236 isapnp=0 port=0x530 cport=0x538 irq=5 fm_port=0x388
sb_port=0x220 dma1=1 dma2=0 isapnp=0
in it (all in one line)

That should be it. But, in the process, we've created a bug. Running
shutdown -h now
does not shutdown the computer. The above mentioned link suggests a
fix: create the file
/etc/modprobe.d/power
and in it write
options apm power_off=1 realmode_power_off=1
However, that didn't work for me.

Please write back in case there are any questions. I'd be very happy to help!
