If the Accuphase took it, it was probably 2channel PCM since, AFAIK, all 2 channel DACs will ignore mch and DD or DTS, regardless of the number of channels. Somehow, you/someone must have set the PS3 to do this. If not, you should.

I vaguely recall a settings menu in the PS3 itself that allows it to default to PCM 2-ch. I'll have to navigate and double check.

So even if the on-disc menu provided for only DD5.1 and DD5.1 uncompressed, I guess the PS3 processes it down to PCM 2-ch. ?? The Accuphase DAC had no problem locking on to the signal coming down the optical pipe from the PS3.

Thanks Kal.

  Yes, the PS3 can downmix to 2 channels when it processes the bitstream and converts it to PCM.
  
  Go to "Audio Output Settings" in the "Sound Settings" menu.

    We're watching another Blu-Ray disc later tonight. I'll have a look then when the PS3 is powered up. Thanks for the tip.

      In the audio menu, the PS3 isn't set for Dolby Digital or DTS output: it defaults to 2-channel PCM. The multi-channel soundtracks are decoded to PCM and then down-mixed to stereo.

        I'm good to go and no longer worried that I'm missing any audio. The PS3 is in fact set for 2-ch PCM which is what I need for now since my system has recently gone 2-channel only.
        
        I will augment the 2-channel setup with a Denon 3808CI receiver someday for 5.1 duty.

        Abe,
        
        When you do get the Denon 3808CI you'll love it! I've had one for 6 months and love the new audio codecs they do sound better both in clarity and dynamics.
