There are three volume sliders labeled S/PDIF and the second one has "Default" tacked on to it. All three have volume set at zero and alsamixer won't allow any change. The default should be HDA Intel PCH. I have a strong suspicion that there's a config file somewhere that somehow got messed up, but all the config files that I'm aware of that might have anything to do with sound match those on a machine with working sound.

The only function key that works is F6 (Select sound card). F1 - F5 are supposed to do other things but they all cause alsamixer to exit. Does it matter that I'm running alsamixer from the command line? If I need to invoke it from a GUI, how can that be done? Thanks for your help, Jeff
