I'm using foobar2000 with wasapi output connected via hdmi cable to a onkyo receiver, audio quality is flac/loss-less format. Volume on htpc is set to default max in windows audio control. Even tried xbmc, jriver, and media monkey with wasapi output selected. Everything sounds fantastic crystal clear & quality is amazing. Then I decided to compare it with the exact same song selections, copied it to a usb flash drive, played it through the front usb panel on the receiver. I would play the 1min of a song, toggle back and fourth between the htpc & usb drive. I noticed a difference in sound, Its not really too noticeable unless you're really concentrating on it, the quality of the audio playing from the usb drive that's connected to receiver has a little bit of oomph it in, it has a bit more fuller sound, noticeable specially on track that has bass. Volume wise sounds about the same, planning to get a spl meter to verify. Not sure if this is happening on the blue-ray HD audio playback, since I built my htpc, i got rid of my blu-ray player, so i have nothing to compare it to.
Has anyone experienced this, if so any suggestions or settings I can try on the htpc?
Here is some of my system specs:
Htpc: A8-5600K with Radeon HD 7560D graphics
Receiver: Onkyo NR-809 strictly in "pure audio" mode when listening to music.
Speakers: Klipsch RF82II
