Hi together,
first let me say " Sorry for my bad english" I hope you all understood what i will ask ?
I have found many threads with the question how could i get sound over hdmi or sound over spif. But no thread where i could find help with ac3 and dts sound over spif and simultaneous ac3 and dts downmix over hdmi to my tv. Downmix because my tv couldn´t play DTS sound.
I´m a total windows user, but XBMC runs smoother under linux with my Zotac ND22. So i installed a german project called Ztreambox (http://www.ztreambox.org).
All runs very fine, but only the sound makes me trouble.
if i make aplay - l i become the following:
Karte 0: NVidia [HDA NVidia], Gerät 0: ALC888 Analog [ALC888 Analog]
Sub-Geräte: 1/1
Sub-Gerät #0: subdevice #0
Karte 0: NVidia [HDA NVidia], Gerät 1: ALC888 Digital [ALC888 Digital]
Sub-Geräte: 1/1
Sub-Gerät #0: subdevice #0
Karte 0: NVidia [HDA NVidia], Gerät 3: HDMI 0 [HDMI 0]
Sub-Geräte: 1/1
Sub-Gerät #0: subdevice #0
then i have found an .asoundrs with the following :
with this .asoundrc and the xbmc settings on both outputs to custom (user-defined) "plug:both" i have sound on the av receiver over spif and on the tv over hdmi. But only ac3 no dts. Because my tv could no dts audio. I need to downmix the dts audio. If i switch in the xbmc system audio settings the point dts capable receiver to off. Then all sound will come as AC3 audio to my receiver. I hope you understand what i will say. The DTS Audio plays as AC3 Audio. I dont know if this is a problem in the sound quality.
Could anyone help me with my problem so that i have ac3 and dts audio over spif to my av receiver and simultaneous a ac3 and dts downmix over hdmi to my tv ?
Background is that i watch my movies over a beamer and so the sound comes over the av receiver, but when my childrens watch there movies the watch over the tv. So i need the ac3 and dts audio over the tv.
Hope that anyone could help me.
Thanks
