Excuse me, I've got Asus Xonar D2 and on fresh installed OSS4 it's got 75% pcm volume. Is it necessary? I've read that in original windows drivers it's for 0db gain, but generally Xonar sounds on Windows much louder, so is it on Xonar 75%, or "75%" of 75% set in windows drivers? I think that when I've set 100% on pcm I haven't noticed any noises in sound. In fact I've switched to OSS from ALSA just because of on ALSA my integrated sound card was about 2 times louder than Xonar and I had to set 100% volume on my speakers. And It sounded a bit awful because of quite bad quality amplifier in Solo 6C.
I've written script to switch between pcm 75:75, vmix0 18 and pcm 100:100, vmix 10.5 (it's the same loudness) and I can't hear any difference. Does it mean, that I can set pcm 100:100 and operate only vmix volume without losing any sound quality? Won't it be harmful for soundcard or something?
