I have recently purchase some audio equipment and am wanting to get the most out of it. From what I've read, an OS/media player will tend to "resample" audio frequencies at the software/soundcard level before sending it, and from what I gather, that isn't a perfect 1-to-1 copy of my audio to my speaker. My equipment:

Ubuntu: 11.04 x64
Mobo (integrated sound): ASUS P5QL-CM (http://uk.asus.com/Motherboards/Intel_Socket_775/P5QLCM/) - S/PDIF out on Intel G45 chipset / VT1708B, 8-Channel High-Definition Audio CODEC
AV receiver: Onkyo HT-R380 (PDF manual (http://www.eu.onkyo.com/dl/1465282/Manual_HT-S3305_HT-R380_En.pdf))
Speakers: Stereo (connected to 'A' ouput on AVR) - Acoustic Research Red Box II (circa early 90s)

I have the ASUS S/PDIF 'addon' and I have Ubuntu set to send audio through that.

I think "bit streaming" is what I am after but I am at a loss as to how to make it happen.

All comments/help appreciated! :guitar:
