consider games that output either 5.0 , 5.1 , 7.0 or 7.1 .
I know that Pro Logic IIx up-mixes 5.1 to 7.1 , but how about games that output only 5.0 ? will 5.0 be up-mixed to 7.0 ? or 7.1 ?
Dolby headphone takes 7.1 and virtualizes it , will it virtualize 7.0 ?
I guess in both cases the games do not output sub-woofer , but the question is will Pro Logic IIx and Dolby headphone work without the sub-woofer channel ?
another question :
I have 7.1 speakers, If the game i have outputs 5.1, playback devices set to 7.1 , will all speakers be active ?
Logically thinking the leftback and rightback speakers should become inactive since only 5.1 channels are outputted ? anyone ?
