I would have thought the error message be rather self-explanatory.

Do not use this device, but one of the other one showing up in the
list after you scanned for audio devices

no it doesn't.
It cause the hdmi alsa device to not exists anymore ; so you need to
configure another one, which would happen to be the one you've defined
in the .asoundrc

You configured myth to use a specific alsa device. You then modified
the alsa configuration causing that device to either not exist anymore
or not be usable.

You now need to edit the audio properties again, scan for the audio
devices and select a different one. The error you are seeing only
tells you that your old config isn't usable

I've already given you a simple way to fix you problem by selecting
StereoPCM and not having to mess up with the alsa configuration.

Why can't you just use that and forget about your problems ? what's
the point in wasting time like this?
