5.1 sound from HTS3538/12 via SPDIF
I have 47PFL4007/12 TV and HTS3538/12 home theatre system. And I am planning to buy a mediaplayer (HMP5000) but have a concern. Since yesterday I tried digital optical connection between Dark mania media player and my HTS but there were only RAW and stereo options via SPDIF. And the sound was too bassy even I changed all relevant settings(Subwoofer Volume, bass settings etc.) to bottom. I need to know whether there is multichannel(5.1) option in SPDIF of HMP500. Another question how can I decrease bass and increase treble in addition to bass/treble settings. May I use a potentiometer to set subwoofer volume externally?
Thank you for your answers in advance.
