So i tried DTS-HDMA and Dolby TrueHD without success.
when i play DTS-HDMA, my receiver display DTS-HR and seams to play dts core
with lots of interruptions.
and when i play TrueHD, my receiver display TrueHD but doesn't play

and sysctl show:
dev.pcm.4.play.vchanmode: passthrough
dev.pcm.4.play.vchanrate: 192000
dev.pcm.4.play.vchanformat: ac3:2.0

i tried without vchan with same results.

i can't set more than 2 channels for my hdmi output (dsp4), i want to set 8
channels like alsa does.
i never show things like PCMDIR_...: Stream setup.... in my messages, so
may be i use oss wrongly.
you can find the source code of xbmc used to play losseless file here:
