Hi,
This morning, I did more tests in relation with the sound problem.
I tried connecting the U5 to another receiver via HDMI, a Yamaha HTR-6260, and I can confirm the same results; no 5.1 sound from the Buzz TV Apps, in all situation the Yamaha reports "Stereo" only, but if I use an alternative player, like the XCIPTV, I have 5.1 sound.
I also installed another player; "IPTV Extreme Pro", and after a few tweak, it also play with Dolby D 5.1 on both receivers. In fact by default in Extreme Pro the "Audio HDMI Passthrough" is not active in the sound setups, turning it ON, did the trick and now that player also output 5.1 sound on both receivers.
So this make me remember that the original post indicate: "Fixed a bug with HDMI Passthrough on 5.1 and 7.1 Audio". Maybe that "Fixe" do not work for me, or did it have some switch to turn it On/Off? If so where it is? I search in the U5 setups or Buzz Apps Setups, and did not find anything related to this.
Bye
Jacques
