Good :)
BTW, there is a newer version (which was actually applied) of this patchset in alsa-devel@, seems you were missing from CC on that one.

For the record, the "howto" is mostly a workaround for missing DEV=[1..3] on (now) very old systems, instead of messing around with asoundrc you can just use "-D hdmi:CARD=Generic,DEV=0,AES0=6" instead of -DhdmihdtestX. (in AES0 the 0x2 is non-PCM flag, 0x4 is non-copyright flag IIRC - ALSA default is 0x4).

Nope (well, any that I still remember). Support is there, though, so I guess it should work.
