I have a yamaha RXA1050 AV and was wondering if anyone has any recommendations on the best sound card and best physical connection to get best out of the music from my PC to my Amp please? I'm currently using HDMI cable from my PC to AV connected into my Asus Nvidia GeForce GT640 2GB GDDR3 card. The AV always reports the audio as PCM unless I play a Video which has a 5.1 soundtrack contained within it via VLC player. However for playing normal music mp/flac files it always reports it as PCM on the Amp. Is this normal?
