Hi, I'm trying to setup my HTPC Linux box as HQ/"Audiophile" player. By default pulseaudio re-samples all played files that don't match default or alternate sample rate to those rates which is not appreciated in this scenario. After some trial and investigation found reason for not working original patch of high sample rates playback without re-sampling posted here: https://patchwork.freedesktop.org/patch/124196/ This patch alternates src/pulsecore/source.c, but for successful implementation src/pulsecore/sink.c need to be patched too. With this implementation are files with high sample rates played with their original sample rates without re-sampling if your HW supports media encoded sample rates. I've successfully tested 44.1k,48k,88.2k,96k,176.4k and 192k flac files played with VLC on SundBlasterX G5 DAC.
