"Earlier this week, we met up with the AV team from the ASUS headquarters in Taiwan and they showed us what their continually evolving Xonar HDAV1.3 Deluxe audio card is capable of doing on the HD movie aduio front.
Forum users over at the AV Science forum (this thread) were initially very excited to hear about a proper HDMI 1.3 audio card finally hitting the market – the HomeTheater HD from Auzentech is also on the way, but seems to be getting constantly delayed. Sometime in September this year, the cards finally went on sale, but audio enthusiasts were left disappointed, as the card could send out a LPCM signal, but not via bitstream. The ASUS AV team heard the cries, loud and clear. They got to work and continually developed the product with a series of driver updates, which eventually led to the Xonar HDAV1.3 Deluxe audio card being able to bitstream TrueHD and DTS-HD / DTS-HD MA on the PC. ASUS credits the close relationship with ArcSoft and CMedia for making it all possible."
