Hi, when I watch HD MKV movies encoded with DTS soundtracks, the bass is really low. I have to turn my sub all the way up and sub volume on receiver to +10(highest setting) and the bass presence is still low... with DD soundtracks i set volume about over half and around 0 to -2 on the receiver end. Anyone have this problem??? Using MSI board with HDMI and spdif out to Harman Kardon avr-247 receiver...maybe there is a setting I am missing? I have ac3filter set to use spdif and output same as input and use spidif for ac3 dts mpeg audio, DTS conversion turned off SPDIF DTS Mode on Auto. I think that covers the setup, any help would be great. Thanks in advance!
