Onkyo txnr616 - HDMI sound standby

Hi,

I bought the Onkyo tx-nr616.
Its working just fine, connected to the xbox, DVD player and cables, all working with HDMI connectors.
few days ago I added the HTPC (Intel i3 HD 4000, Gigabyte H77 on board realtek sound...) basically everything is working as expected but I have this weird problem, as start for a second I miss the HTPC until the receiver realize that sound is passing through.
for example I cant here a short sound like the windows lower right sound volume (near the date...) but a 2 hours movie I hear with no problems.


Someone knows about this issue? its relegated to the receiver or the HTPC?

Thanks!
Ronen

someone?

no way, working with regular speaker connected to sound output of the computer is working perfectly.
I think its related to the HDMI.
