Hi,

I am no expert and need advice on the correct audio set up for my system.

I have a Panasonic TH-P50V20A plasma TV which is connected to a Yamaha YAS-101 Soundbar via the optical output of the TV. I have a Panasonic DMP-BDT 220 Blu-Ray Player connected to the TV via HDMI.

I am confused by the various settings available for the audio of each unit and want to ensure that I am getting the best possible combination for the Blu-Ray player

For the TV I have options for Digital Audio Preference - Dolby D or MPEG; SPDIF Selection - Auto or PCM; and MPEG Optical level

The Soundbar basically accepts the optical digital signal output from the TV

The Blu-Ray Player audio output is via HDMI to the TV and I have options to control the PCM Down Conversion (?) plus a Downmix option for multi channel to 2 channel sound (?) I don't understand these Downmix settings...

Can someone please give me some guidance on how to get the optimum result from this set up

Cheers & Thanks

The display and blu-ray player should sync automatically over the HDMI connection so that only a supported audio format is used. Sometimes things don't work as they should in which case set the blu-ray player to always output 2ch PCM (i.e. down mix multi channel to stereo PCM).

TV-dolby d change to mpeg if you get no sound from soundbar. spdif auto, leave downmix alone unless as beejay said you have any sound issues.

Thanks beejay76 and stormAV for your responses. I have done exactly as you suggest.

SoundBar is fine with Dolby D, SPDIF set to Auto and Down mix set to 2 channel PCM stereo - there is no Off setting for Down Mix

Thanks again

Cheers

The reason for setting/forcing 2ch PCM in the player is most displays can't decode bitstreams so you need to do the decoding (and down-mixing to 2ch) in the source (player).
