Another striking feature of the new ATI cards is a built-in audio controller that grabs audio output through the PCI Express bus and transmits it through HDMI. Unfortunately it supports only Dolby Digital 5.1, DTS and 32kHz, 44.1kHz, 48kHz/16-bit PCM stereo. Although it is a step forward toward the true HDMI audio, practically there is no advantage over the current S/PDIF passthrough solution.
the only way to take the full-rate lossless multichannel sounds from the PC is use analog outputs.
