LOL! Thanks for the clarification.

You probably know about that Microsoft/Intel "Standard", the AC97/PC97
according to which all sound-processing has to take place at 48 kHz,
regardless of input. So most cards resample everything at 48 kHz. I
came to Linux because I was sick and tired of MS/Intel and would want
my sound-card to output the digital stream exactly as it is.

So I assumed that the resampling to 48 kHz would degrade quality, to
confirm my assumption I tried to encode the same wav (from Audio-CD)
once with the usual 44.1 kHz and then with 48 kHz. I wanted to compare
these outputs (assuming, the soundcard does not do any more "clever"
resamplings at 48 kHz).

This darn MS/Intel "standard" is very annoying, if you want bit-exact
outputs, like e.g. AC-3 or DTS-Streams (DVDs).

Kind regards    Frederick
