The usual method I used for DSL sadly doesn't appear to work for DSL-N. Anyone been able to figure this out?
Thanks |

After about 5 hours I have sound working on my IBM Thinkpad 600E running DSL-N 0.1 RC4 from a HD install.
You have to add the alsa bootparam on the kernel line in the /etc/grub/menu.lst file otherwise it autodetects the cs46xx chipset and doesn't work.
After booting no driver actually gets loaded so you have to run
modprobe cs4232
then fiddle with the mixer to get the volume up.
I haven't figured out how to get it to automatically load the cs4232 driver yet and the mixer settings don't save.
One other thing is that sound works, but going to a couple wav audio file sites to test has shown sometimes the wav file gets cut off before it should end... it happened too many times to be bad wavs. Something I read on another TP linux page said something about irq or address settings.. I have to research a little more.
Also, if anyone hasn't gotten it to work well, the video autodetects the proper chipset but sets itself to 32 bit color which skews all the colors on the screen. Even selecting 24bit (which it supports in windows fine) doesn't work. DON'T select any fb stuff, that's just plain slow - use xvesa but select 16 bit color and it works great and fast.
whew.. almost done getting this right! |
