Wow, you really do have a handful there. I'm starting to think the alsa
handling in myth is a little 'delicate' (please don't toast me devs, that's
not a complaint or a criticism!). Something I've been thinking about lately
is whether some dmix/dsnoop magic in ~/.asoundrc might be useful in strange
cases like this.
