[Bug 61211] Re: "Your audio capture settings are invalid. Please correct them in the Multimedia settings." is a really unhelpful error message

[^rooker]

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
===================
