I'm afraid I celebrated too soon. While it is true that running the udev commands you indicated and reinstalling alsa-base worked as long as I kept my computer on, when I turned it off, somewhere it must have changed configuration files -- because when I restarted the computer, sound was not working again, and it gave me this error:
ALSA lib confmisc.c:670:(snd_func_card_driver) cannot find card '0' ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_card_driver returned error: No such device ALSA lib confmisc.c:391:(snd_func_concat) error evaluating strings ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_concat returned error: No such device ALSA lib confmisc.c:1070:(snd_func_refer) error evaluating name ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_refer returned error: No such device ALSA lib conf.c:3968:(snd_config_expand) Evaluate error: No such device ALSA lib pcm.c:2143:(snd_pcm_open_noupdate) Unknown PCM default === Could not load default driver and no driver specified in config file. Exiting. Furthermore, when I tried to run the udev commands you indicated followed by "apt-get --reinstall install alsa-base", that did not solve the problem again. So there seems to be some mystery here. FYI here are some files that look relevant, but I don't know where to go from here. % cat /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line.
