from looking at the ATI 4870 specs it says it does 7.1 audio. Now at the minute I am running sound from my motherboard which as we all no is crap quality.
If I buy the 4870 card will it send the audio from the games I play direct to my AMP ?? If not looks like I am going to have to buy a sound card
any help is appreciated !
thanks
As long as you send it to a receiver that has atleast an HDMI 1.1 repeater, you are all set.
The software for BD/HD such as PowerDVD Ultra can decode the advanced audio codecs and output as PCM.
The only current issue with PCM is lack of exclusive control. If you set the audio config for 7.1, then you are unable to apply post processing for matrixing. So, if you output a 2 ch. PCM signal, 7.1 is sent to the AVR, with 5.1 info being blank.
With my 7.1 setup, I output 5.1, thus allowing the ability to matrix 5.1 to 7.1. If I NEED to matrix 2.0 PCM, I can simply change the audio settings.
Newer sound cards should be able to bitstream the advanced audio codecs, resolving this issue. But, with the 4*** series gfx cards, it's like getting a sound card for free..
