- My HD CableTV box is outputting DD5.1 cos when I hook it up via HDMI to the V673, the decoder info indicated 'Dolby Digital'.
Although in this instance the cable box is likely passing DD 5.1, note that it can also likely pass DD 2.1.
>>> Hmm... if the V673 indicates 'Dolby Digital' and 7.1 speakers lights up, is it DD5.1 or DD2.1? If not definitive, how then can I find out?
- To test if my TV supports DD5.1, I connected my BDP to TV and playback DVD movie with DD5.1 and it has got audio. Even pass thru from BDP > V673 > TV also has got DD5.1 audio. So problem does not lie with the Panasonic TV.
More than likely the TV actually "cannot" accept DD 5.1, rather once the BDP recognizes a stereo device is connected, it will pass the stereo track stored on the BD.
>>> The specs of my TV indicated support for 'Dolby Digital Plus / DolbyPulse / DTS 2.0+Digital Out'. (specs here: http://panasonic.net/avc/viera/asia/et5_lcd_spec.html
). Didnt specifically mentioned 'Dolby Digital' but only 'Dolby Digital Plus'. Is the Plus similar/compatible with plain Dolby Digital 5.1?
- Directly connecting cableTV box to TV via HDMI without pass thru via V673 = no audio with DD5.1 enabled, but has got audio when DD5.1 is disabled. Tried different 1.3b, 1.4 highspeed HDMI cables no difference in result.
The cable box can only pass what you direct it to pass. As the TV cannot accept DD 5.1, trying to pass it from the cable box results in no audio from the TV's speakers.
>>> Havent gotten reply from the Panasonic tech support to confirm if Dolby Digital 5.1 is supported or not.
