S470 doesn't play sounds via wi-fi

[upsipupsi]

My new blu-ray player does not play any sound when I use, for example, Eurosport or Yle Areena channels  (or any channels) via wi-fi. Also via twonky manager I can not hear anything when playing music from my computers or phone.

Further, any videos do not work via twonky. Photos do work nice. I have win xp and normal one antenna 54 M router. Do you have suggestion to try? Thanks!

How is it connected to your TV?

The player is connected to tv by a normal hdmi cable.

Now I have got videos to see via wifi. still they don't have sounds except those I have demuxed with ProjectX-program to .m2v or something like that.

Does it play sound if you play a dvd of Blu-ray? I'd try a factory reset to see if that makes a diffference. Sounds like its an output problem from the player to the TV.

Thanks
