Sound on Thinkpad 600E
I am a newbie Knoppix user with a little Linux experience. I have installed the 11/19 version of Knoppix on my IBM Thinkpad 600E. Everything works okay except for the sound. I think "sndconfig" sees the the wrong chip and loads drivers for it. I also get a message, when Knoppix boots, that the file "dev/dsp" cannot be found. I have seen various fixes on the web about adding lines to the "modules.conf" file and have tried them, but no luck so far. Has anyone successfully gotten sound on their 600E? If so, how did you do it?
Thanks in advance!

I have a thinkpad 600E here and the only module that ever gave me sound was to use the soundblaster pro one. That was the case with any distribution and even then I got problems - no sound after suspend/standby and any PCMCIA activity caused major buzzing from the sound system.
Part of the problem, as I understand it from speaking to IBM on several occasions and also SuSE, is that IBM had different revisions to what was nominally the same sound system. This causes real headaches for getting sound to work - I'm not sure why these problems have so much effect on linux where Windows sound generally worked (although far from perfectly).
I had tried the OSSfree and ALSA systems and with various distributions (Redhat, SuSE, mandrake, Knoppix) without any luck. In the end, I gave up with the idea of sound under linux and simply pretended the machine had no sound functionality at all.

On my 380XD I know that the soundchip wasnt at the normal location, so I had to fiddle around with that. I'll see about digging up what I have for ya
-
If anyone finds a fix, could ya pass it to me too?
Thanx.

Got my sound working on my TP 600E, don' t have the instructions I used with me now but when I get home this afternoon I'll post them here. Now all I have to figure out is how to get the Modules to load at startup, found a script on IBM's website but haven't rebooted to test it out yet I'm hoping I put it in the correct location. If anyone knows or has a good script to do this with I would appreciate hearing from you.
I'm fairly new to Linux but have to say that this forum and also the LinuxQuestions forum have been a great help.
Thank you to this community and look forward to adding my new knowledge to it.

I don't know if the soundcard is the same, but I used to use this on my 600x:
You can use lspnp to check to see if your card is detectable.
lspnp -v 0e (on my 600x it's 0e, you can just you lspnp -v to see all your pnp devices)
setpnp 0e io 0x530,0x388,0x280 irq 5 dma 1 dma 0
modprobe cs4232 io=0x530 irq=5 dma=1 dma2=0
Mine was weird because I had to reverse the dma settings from what I thought they were. If lspnp does not show your soundcard, you may be scrod, as they say. I don't know if knoppix has the PnP bios patches that you need to get the PnP bios to work right. I seem to recall I had to use the -ac patches on my kernel to get the PnP bios working.

Here is what I did
Open a shell and logon as root and type
insmod sound
insmod ad1848
insmod uart401
insmod cs4232 io=0x530 irq=5 dma=1 dma2-0 mpuio=0x330 mpuirq=9
this will load the correct drivers, however you will have to enter this everytime you reboot so if anyone out there has a script that will run these commands on boot I would appreciate hearing from you.
Update: I finally got the mods above to load at boot what I did was create a file with the above commands and saved it as cs4232 in the /etc folder and made it executable.
Then cd to /etc/rc5.d and ran
ln -s /etc/cs4232 S98cs4232
this created the symlink and I then rebooted the laptop and sound loaded on start.
Thanks to everyone here who helped me out and I'm sure I'll be posting many more questions, as I get farther into using this wonderful OS.

Had a similar problem on my 600. Couldn't get it to work correctly using modules.conf, so I wrote a little script which was called from rc5.d.
Posted it back in march.

Have a look, it should set you in the right direction, even if your actual values for io/irq differ.

I never got that script to work, it runs when I boot but gives some errors... (insmod failed... i think)
I seem to get the same errors when I dont run the commands as root, but I cant find any logs for when it starts (unless I scroll up after pressing Ctrl Alt F1). However I checked the kernel logs and it loads the driver with the errors:
Code:
cs4232: set synthio and synthirq to use the wavefront facilities.
cs4232: Must set io, irq and dma.

Weird, Do you have the io etc. correct in the script?
