Laptops :: sound Thinkpad 600
Hi, stumped on this challenge. Have read everything I can find on the subject. Each approach falls short on my T600. The dsl distro is great, otherwise. The basic problem is that I don't know what should be where. The sound chip is a Crystal 4237b. When I "insmod cs4232" I get "unresolved symbol ad1848-detect"...init,control,mload. I have tried to configure /etc/conf as suggested without success. The Linux how-to directs one to configure hardware with /sbin/setpnp (but how?) and then says to create an /etc/modutils soundfile and run update-modules. What kind of soundfile? With what name? I understand that dsl uses OSS. Where can I look for an explanation of what is required. I'm sure this is solvable. TIA for any suggestions.
I had similar issues with my IBM 770..
Does "insmod uart401" give errors.
( if it gives you back a prompt, your good...)
Add your io, irq, and dma info to your modprobe request.
See this thread for what I did....
http://damnsmalllinux.org/cgi-bin....;hl=770
Rather than place the info in /etc/modutils/aliases, and run update-modules,
I placed the modprobe commands in the bootlocal.sh, and saved that
file in my backup
" iinsmod uart401"
" insmod cs4232 io=0x530 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=5"

Thanks for your help. The insmod uart401 did return a string of errors (unresolved symbol ad1848-detect, etc.) and then a system prompt. I put the two insmod commands into bootlocal.sh and rebooted. The same errors were listed with additional symbols unresolved from the second insmod command. XMMS will play a CD but no sound comes out. The speakers beep properly when asked to by the system, and the keyboard control of this beep volume works properly. Do you have any further suggestions? Looking forward to installing .8! Great work!
We must be close...
