Yes, but why wasn't it there in 790GX and 785G then? Same 4xxx series Radeon.
I would suspect that AMD might be fighting for every milliwatt in this chip and give up PAP support logic for die size and power consumption.
Although, I could be wrong. In November PC Perspective said that "According to AMD, the official specification sheet includes: DTS-HD Master-Audio Bitstream Capable - Yes"
Zotac announced HD audio bitstreaming in its Brazos-based ZBox
But why there was nothing about it in AMD press release? They mentioned UVD3 but not HD audio.
