I've done all this and am still getting the "Couldn't open audio" error. The computer has been using an external USB "soundcard" and I've long since removed the old soundcard from its slot. Do I need to add some usb-related lines to the 52-sound.rules file? xmms returns these error messages: ** WARNING **: alsa_setup(): Failed to open pcm device (default): No such device ALSA lib confmisc.c:848:(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:397:(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:1248:(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:3972:(snd_config_expand) Evaluate error: No such device ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM default ** WARNING **: alsa_setup(): Failed to open pcm device (default): No such device This is all very interesting.
