Don't know if this is related to freedombox/usound or not, but it appears to have happened after I installed freedombox and ran usound. I have kernels with commerical oss and I have kernels with the sblive support (just under general sound in 2.4 kernels; under oss (deprecated) in 2.6 kernels). the reason I had kernels with both is that sometimes when I upgrade commercial oss there are temporary glitches (mainly because of differences of debian from other distros) and I want a backup. well, this has been working fine; both sound systems have been working fine. Now, although my commercial oss is still fine, when I switch to a kernel with built-in sblive and try to run most applications, i get errors about "/dev/dsp: no such device" and oss not opening. /dev/dsp is indeed there, along with al the other /dev/dsp devices. I'm in the process now of modularizing it to see if that will give me any further error messages, but this is really weird. Could usound and/or freedombox have changed something or is this totally out-of-the-blue unrelated? Thanks. -- Cheryl "Where your treasure is, there will your heart be also."
