Question Crackling on 5.1 setting, delay on Dolby Atmos setting Question Dolby Atmos vs Dolby Atmos/ DSur Most media players will decode the surround sound signal with the default settings, you have to either remove the decoder or tell the program to send the audio to the soundcard using S/PDIF.
If you tell us what media player you are using, maybe we can tell you how to make sure the surround sound signal isnt being decoded before being sent to your soundcard. You would need to stop the media player from decoding the surround sound signal. You would have to turn on the dolby digital live or dts connect encoder to put the signal back into a surround sound format.
If the software you are playing the movie with is decoding the surround sound signal, the program will send a signal to your card that isnt a surround sound format. because they dont switch between 'prologic' and 'dolby digital' I'm not sure if you are confused with the PLII music and PLII movie choice. What you are using to play the movie might be causing a problem. You'll know its working when sound comes from only one speaker in the back and not from the front. When you have PLII music or PLII movie selected, are you getting invididual sound from the rear speakers?
and that is how i know the signal is surround sound and not stereo. There is no option to turn off the 'prologic' part, but individual sounds come from my rear speakers. I too can choose from prologic II movie or prologic II music. My receiver lights up with 'prologic' whenever i send it a dolby digital signal. I'm using an optical connection from the speaker system to a HT Omega Claro Halo sound card so I don't understand why I can't get the settings to show.
My only options are Stereo, Stereo x2, PLII Movie, and PLII Music. So I bought a Logitech z5500 sound system and everything works great, except I can't seem to get DTS or dolby 5.1 to work.
