The audio from the Sony Bravia KDL43WE753 Netflix app keeps dropping out when output to my Yamaha RX-660 receiver in Dolby Digital 5.1. The dropouts last less than a second, but are really annoying as they happen regularly (the time between each dropout seems random. Sometimes the audio is fine for several minutes, but other times they happen every few seconds). I’m currently having to change the tv output to PCM whenever I want to watch Netflix.

Only the tv’s Netflix app has the problem. I don’t have the problem in any of these scenarios:

- Digital Audio Out set to PCM (i.e. not using 5.1)

- Netflix app on my Virgin TiVo box output via hdmi to TV then on to the receiver using the tv’s Digital Audio Out of Auto1 or Auto2 (this was almost a workaround, but the picture quality is very poor from the Virgin box)

- Blu-ray player via hdmi to tv then on to the receiver, as above

- any other 5.1 digital output from the tv (e.g. from HD TV channels)

I’ve done a range of things to try and solve the issue, but nothing’s worked:

- Tried 3 different HDMI and 1 optical cable from the tv to the receiver

- turned ARC and BRAVIA Sync Settings on and off in a variety of different ways

- set Digital Audio Out to either auto1 or auto2

- set Dolby Digital Plus Out to either auto or off

- restoring factory settings

 Does this tv have an unresolved problem with its 5.1 Netflix output, or is there something I need to do?

I’ve run out of ideas, so any help would be much appreciated!
