I have a problem that is baffling me. It started yesterday when installing asmixer, which promptly failed to open /dev/mixer. The problem seemed to be solved when I deleted the file and linked it to /dev/audio instead; mixer ran fine, sound played as usual. However on reboot sound stopped altogether. ASmixer, and anything else for that matter, can't open the sound device. I tried re-compiling the kernel, without change. Have I damaged my sound system beyond repair?
