My PS3 slim is set to bitstream to a Harman Kardon AVR-265 and the video goes through to a 42" Sammy.

Unfortunately irrespective of the codec (DD, Dolby TruHD, DTS HD MA) there're dropouts in the audio. The receiver picks up the stream again almost immediately, but the logo blinks in the receiver and the OSD via the receiver's processing pops up.

The video stream is unaffected and stays steady.

I looked in the PS3 slim audio issues thread but according to that only Pioneer receivers were affected and with DTS HA MA at that. My issue occurs with any kind of bitstreaming.

PCM is unaffected but the volume levels are lower and it generally sounds 'worse'.

Is this a known issue? Googling produces other people who've had this issue with 3 different brands of receiver with no solution.

The HDMI cable is a 1.2 cable.

Run PCM, it does not sound worse. HDMI is intended to do all decoding on the source side, always sending PCM out. Bit streaming is what happened once marketing got ahold of the spec.

Solved.

Dude, it sounds quieter and is quite definitely 'worse' The bass sounds subdued with everything else set the same. It's quite clearly noticeable.

yeah the 6-8db is noticeable. But the answer is to use PCM and turn the volume up.

For the past few months I've had issues with the center channel randomly dropping out in the middle of a blu-ray movie on a Yamaha RX-V663 receiver. For everything else, it works fine: playing video games, streaming Netflix, and watching TV. After reading this thread, I decided to check my settings, and sure enough I was set to bitstream. I switched to PCM and had a nice glitch-free viewing of Snow White and the Huntsman last night. I had to turn up the receiver 3 clicks, but no biggie.

The human audio sub-system is terrible and very easily tricked. As such, lower volume sounds "worse" to us. It's the primary reason that people think dts sound better than Dolby Digital, even though in reality it's really a matter of six of one half dozen of another.

So "dude", again just set it to PCM, the correct setting.
