Hi,

I assume that this new BDP is connected via the same HD621 HDMI input used and other than swapping players no other changes have been made.

If this is the case then the most likely cause is that the BDP is outputting 2 channel not multichannel.

I recommend going into the BDP's HDMI audio configuration and setting it to output multichannel PCM.

Regards,
Carl
