FWIW, radeondrmkms has this audio depends on video problem. i noticed
that hdmi audio works mostly fine in netbsd-7, so i tried to switch to
it. unfortunately there are at least three problems i need to look at:
- the display must be unblanked (ie, the "xset dpms" standby
time matters) -- ie, this problem
- after a little while, it starts dropping parts of the audio
in a stuttery effect -- maybe on/off cycle every second or
so. pause and continue in audio apps seems to help that
- there is a 1-1.5s pause when (re)starting where there is no
audio output
for now i'm back to the analog cable.
.mrg.
