Thanks to everyone who wrote with helpful advice. I have tried most of the suggestions, and am still getting no sound. First I got the agnula kernel. I used the advice at <http://ccrma.stanford.edu/planetccrma/software/installkernelandsound.html#SECTION00023200000000000000> to configure the alsa implementation. When I ran that, i got no sound and no error message. I downloaded the 2.6 kernel, and got a kernel oops when I tried to reboot. I tried booting the knoppix CD, which has kernel 2.4.26 and oss, and it wouldn't play sound either. I tried booting back to 2.4.l8, and it doesn't play sound now either. I tried removing the alsa apps and going back to oss, which really used to work. It doesn't now, but it isn't clear that I really removed all the alsa stuff, although the loaded modules look like the oss ones to me. This version gives me an error message when I try to play a MIDI file: $ timidity score.midi Couldn't open output device I have some questions, none of which may be relevant, but I really need sound to work: I believe that via82cxxx_audio is the module for the soundcard that's on the motherboard, which I don't want to use. Why does it keep loading it, even though I have told the bios to turn it off? And how do I make it stop loading this module? /proc/interrupts reports that both the SB-Live and the onboard sound are sharing interrupt 9. Is this likely to be causing problems? Does anyone have any idea what changed between kernel 2.4.18, when OSS sound worked, and 2.4.25 when it doesn't? I believe the 2.6 kernel that I loaded was 2.6.7 -- is it likely that a less recent one would work better? i have checked the connections, and the speakers certainly work when I'm driving them from something other than my computer, and the computer seems to be seeing the SBLive soundcard in the normal ways, but is there any chance that something's wrong with the soundcard that just happened at the same time as I started playing kernel games? Is there anything else I should be trying? -- Laura (mailto:lconrad@xxxxxxxxxxxx , http://www.laymusic.org/ ) (617) 661-8097 fax: (501) 641-5011 233 Broadway, Cambridge, MA 02139
