Steve, I have "some" experience in Alsa, and hope I can provide the answers.
OSS is a sound system for linux, which dates back to before kernels 1.0. It has a number of problems. There is a move to Alsa now, and this has certainly gained momentum with Alsa's inclusion in the standard 2.6 kernel. Alsa has a compatability mode, where it will enable OSS sound systems to still work. With that compatability mode, the modules with oss in their name get loaded. From your list of loaded modes, you have alsa running and the oss emulation mode. Their maybe a need to run alsaconf (as root) to configure the sound devices. Try it, and see. On a hatred (redhat 9, 2.4.20-8 kernel) box with alsa loaded, alsaconf modifies the /etc/modules.conf file, and creates the appropriate configuration information in /etc/asound Actually, check first that the configuration files are there. If not, run alsaconf Alsa will (once running) create entries in the /proc/asound directory. These provide some clues as to the type of card you have. alsamixer is probably the only thing you need to run. Turn up anything that looks like an output. Several useful keys to remember. m toggles the muting. left & right arrow plus up/down arrow. space for capture, f2 for help. Return to exit help. Note that the master should be high. You can easily test. locate .wav (and find the .wav files on your box) aplay some_file.wav which should play sound........ ==== On rereading your letter. The kernel messages look bad. Real bad. I suspect this is your problem. You can try loading in the latest version of the alsa drivers, and not update the kernel.
