Hi there guys!
In my soundcard driver i can choose between 48 khz and 44.1 khz.
Well i think 48 khz is best because it's a higher number but I am not sure.
Cause almost all music is recorded in 44.1 khz?
So what should i choose for the best sound? (All my music is in FLAC)
48 khz or 44.1 khz?
Hope you guys can help me

What kind of soundcard is it?
All CD-based music is recorded at 44.1kHz, but almost everything else is 48kHz (or multiples of). Usually sound cards resample CD audio to 48kHz internally on playback. You generally can't tell - there isn't usually an audible quality loss. If your soundcard actually does 44.1kHz playback (and it probably doesn't) then you can always choose that mode for "perfect" CD reproduction.
FLAC files will have the same sample rate as the source... so if you made them from CD-audio, you have 44.1kHz FLAC files. I have some made from DVDs that are 48kHz though, for example.
