ATi graphics card could only do LPCM audio output but no direct bitstream to AVR for decoding. Moreover, most software Blu-ray players such as PowerDVD, WinDVD, will downsample the LPCM to below 16bit/48KHz audio quality (usually as MP3 bitrate) on general audio/HDMI devices unless it supports AACS compliant protected audio playback as Xonar HDAV did with Arcsoft TMT player. So, you could not get the real uncompromising HD audio inside the Blu-ray disc.
