[Bug 40116] Re: Thinkpad 600e sound hardware not detected with Ubuntu "Dapper Drake" live CD (Flight 6)

[smontano]

I have successfully gotten the sound to work on my ThinkPad 600e on
Ubuntu 9.10.  Here are the steps.

* FYI, I have acpi=force enabled in Grub so there is no need to turn off acpi.  I'm not sure how much of a variable acpi is for this but with acpi=force it works.  (BTW, I wanted acpi=force enabled in Grub only because it allowed my battery meter to appear in the GUI.)
* Prepare your ThinkPad by making sure that you have disabled “QuickBoot” in the bios. You can check this by booting your machine while holding down the F1 key. Also it is VERY VERY important to use the bios Initialize button, then set QuickBoot back to disabled.  Initializing somehow gives Ubuntu a better chance to see the sound card.
* Add this line to /etc/modules

 snd-cs4236

* Blacklist the incorrect sound card in /etc/modprobe.d/blacklist.conf
by adding these two lines

 blacklist snd-cs46xx
 blacklist cs46xx

* Add these lines at the end of /etc/modprobe.d/alsa-base.conf  Notice,
different than instructions for previous version of Ubuntu, you have to
add the "--install-ignore" and "index=0" items to the options line. Also
for those not familiar, the options line needs to be one really long
line that doesn't wrap to a second line in the actual alsa-base.conf
file.

 alias char-major-116 snd
 alias char-major-14 soundcore
 alias snd-card-0 snd-cs4236
 options --install-ignore snd-cs4236 isapnp=0 index=0 port=0×530 cport=0×538 sb_port=0×220 fm_port=0×388 irq=5 dma1=1 dma2=0
 alias sound-slot-0 snd-card-0
 alias sound-slot-1 snd-card-1
 
 alias sound-service-0-0 snd-mixer-oss
 alias sound-service-0-1 snd-seq-oss
 alias sound-service-0-3 snd-pcm-oss
 alias sound-service-0-8 snd-seq-oss
 alias sound-service-0-12 snd-pcm-oss
 
 alias /dev/mixer snd-mixer-oss
 alias /dev/dsp snd-pcm-oss
 alias /dev/midi snd-seq-oss
 
 options snd cards_limit=1

* After restarting you should hear sound at the login screen.  If you do
not hear sound when you are loading up into your desktop, the volume
icon may have an X on it.  For some reason my volume was set all the way
down initially so you can just turn up the volume if this happens to you
too.

Hope this helps!!  :)
