I fixed it. The problem was that the ~/.asoundrc.asoundconf entry for the "default" soundcard was broken:
#------------ BROKEN ---------------- !defaults.pcm.card default defaults.ctl.card default defaults.pcm.device 0 defaults.pcm.subdevice -1
#------------ WORKING -------------- !defaults.pcm.card I82801CAICH3 defaults.ctl.card I82801CAICH3 defaults.pcm.device 0 defaults.pcm.subdevice -1
Here's how I fixed it: (lines starting with $ are shell commands) =================== $ asoundconf list Names of available sound cards: I82801CAICH3
$ asoundconf set-default-card I82801CAICH3 ===================
