Ya, I have that setup also (Panny 850 and Onkyo 607) and it also works fine. It's not included in the above count because it's not ARC (all HDMI v1.3). 850 is older than 10 series.
Be sure both the Panny and Onkyo are up-to-date. Try a heavier gauge v1.4 cable (especially if it's over 6 ft long).
I know it's old, my question is if we have a 2011 repeat of this issue between Panny and Onkyo. I've read every page of this thread (I think I am currently up to page 70) and most of the issues seem to be HDMI related.
I have several different HDMI 1.4 cables of varying thicknesses and all are 6' or under and switching them out does not solve the issue.
The fact that it seems to happen at random times for no apparent reason is leading me to believe either the HDMI board on the 609 needs to be replaced or the ARC channel on my ST30 is going bad. I'll know more later this week when I hook my incoming 60" ST30 up to the 609 to see if the issue still occurs like with the 42" ST30 I am using now.
The one thing I do not want to do is send the 609 for warranty service because I have heard ZERO, repeat ZERO good reports of people dealing with Onkyo's customer service. If anything I'll return it and go with a Denon if I cannot resolve this problem.
Some people on here seem to be content just using optical but the HDMI ARC is supposed to work and I am not going to tolerate a defective unit no matter how convenient the workaround may be.
