I just wrote a lengthy reply to this thread and my browser crashed
Anyway, top and bottom of it was this: If I understand you correctly, you put the PS3 in Bitstream mode over HDMI and tested DD, then put it in Linear PCM mode over HDMI and tested DD again and got exactly
the same bass response? There was no variation in the levels?
I just tried this on my PS3 with 300. Put it in Bitstream mode and got bass on the DD and TrueHD soundtracks, but hardly any on the PCM soundtrack. Put it in Linear PCm mode and there was no bass on any of the tracks. When playing the Dolby tracks in Bitstream mode the amp displayed Dolby D, when playing the PCM track the amp displayed Multich. In Linear PCM mode it displayed Multich for all tracks. If I understood your post correctly, this sounds like what you did?
I have no idea why my amp doesn't produce bass with PCM soundtracks or when my players are in Linear PCM (internally decoding) mode. Bitstreamed soundtracks from my standalone are fine (I get TrueHD/DTS-HD on the display), but PCM is dead. On the PS3 I can't get any bass in Linear PCM mode. The common element is PCM - be it PCM tracks or internally decoded audio output as multi-channel PCM. My wife also heard the problem, so it's not just me.
I am now faced with the prospect of having to pack up a three-day old amp and return it for an exchange. I really don't want to have to do that, because it will be a lot of messing around with the retailer, couriers, getting the shipping refunded and waiting for the replacement to arrive. I will call Onkyo UK's third-party support company tomorrow in the vain hope that they can help me out, but it's not looking good...
Thanks for checking though.
