Sorry to hear of your troubles. I too am a proud owner of a ThinkPad
600, and getting sound set up used to give me fits practically every
other release of Debian. Then I managed to stumble upon a tried and
true recipe.

However, this time around, with Debian 4.0r4, that tried and true
recipe failed to work. Then, a couple of days later, it worked. And
I truly changed nothing in the interim. So my advice is to try the
recipe I'm enclosing here.

All,

On the very same Thinkpad 600 (Type 2645-51U, BIOS IBET53WW), my
previously noted steps failed to get sound working under Debian 4.0r3
and were on track to fail again under (a clean installation of) Debian
4.0r4 (Testing branch). Very frustrating. However, I did, for some
reason, finally achieve success under Debian 4.0r4.

The steps:

0. BIOS (enter BIOS by pressing F1 key while booting)

a. Select "Initialize".
b. Select "Disable Quick Boot".

1. Packages

a. alsa-utils (in order to get /usr/sbin/alsaconf, which seems to
be necessary again)
b. mpg123 (for my console sound test)
c. xfmedia (for my X Window System sound test)

2. file

Must contain these lines:
Quote:
loop
snd-cs4236

3. file

Must contain these lines:
Quote:
alias snd-card-0 snd-cs4236
options snd-cs4236 index=0 isapnp=0 port=0x530 cport=0x538 irq=5 \
dma1=1 dma2=0

4. Blacklist snd-cs4232 module

File must contain these lines:
Quote:
# blacklist snd-atiixp-modem
# blacklist snd-intel8x0m
# blacklist snd-via82xx-modem
blacklist snd-cs4232

Now, for whatever reason, these 4 steps, while sufficient under Debian
4.0r0, were not sufficient under 4.0r3 and may not be sufficient under
4.0r4. Additionally, I needed to:

5. Run alsaconf(8)

Here is where things got strange. I ran and
tried to autoprobe my sound card. It of course again mistakenly
found a cs4232 card. On my first go around, I told it to continue
searching for ISA legacy cards; it found one, and I let it rewrite
my and files. Upon rebooting,
I of course had no sound. I then reran and ac-
cepted that there was a cs4232 card on board. Upon rebooting, the
system hung. After performing a Debian rescue and removing the of-
fending entries in and , I
rebooted. Then I manually followed the first 4 steps above, reboot-
ed, and lo, I had sound. Aggravating to not know why it worked now
while before it didn't.

Regardless, there you have it for sound on a Debian 4.0r4 (Testing
branch) on a Thinkpad 600 (Type 2645-51U, BIOS IBET53WW).

Best,
Eric De Mund
