got sound working- not original poster
Today I loaded 3.3-11-19-03 on my Toshiba 2805-s401. It has a Yamaha ymf-754 which I was told by sndconfig was not supported.
I had booted from CD, then used Ctrl+Alt+F1 to view the boot info, it showed my soundcard, but also the errors that the sound.o file was missing. Booting with "knoppix alsa" option did enable the sound.
But after using the knx-hdinstall script, I received errors in kde saying that /dev/dsp did not exist or was not available.
In a root shell I ran alsa_init and watched it configure the module and load it.
Now sound works, and nicely. I tested it okay in the kde-control-center.
Thanks!
