might not be an xmplay issue, could be wasapi or likely nvidias HD audio drivers
basically my pc playing music via a yamaha sound-bar/hdmi, but if i hit the bars off button or the cat walks on it, xmplay crashes and the nvidia drivers go awol for a bit, then i have to change over to spdif, which just dont have that boom on the lower frequencies my deer old heavy metal requires
i'm gonna do the usual, uninstall n reinstall in safe mode, bios soundcard is off, did a malware sweep, stupid search-dial again popped up
cheers
ps dont forget that lovely glossy black default skin for HD monitors now ;-)
