Yes, nice. But I have not much confidence in good sound when BS like this (and more) is shot at you :

Quote
When a file is to be played which needs, say, a 48 kHz clock, this is then no longer possible with the original 44.1 kHz clock we used for the 44.1k file before. The solution most computer operating systems use to solve this is an extensive array of clocking functions, each running at different speeds and through what is known as PLLs (Phase Locked Loops) which introduce Jitter into the stream. However, the solution is easier in an engineering sense because only one clock is necessary for all of the different frequencies listed above. You can "round out the clock ticks" to get to the frequencies you need. But this "rounding out" probably need not be discussed here with you. Of course, it results in "that harsh digital computer audio sound".

But OK, I guess this text sells and anticipates computer users who actually don't want to be that.

My Attention is more to the minimized/own OS and stripped down MoBo.

I understand. But this is nothing about a real OS. Not that that is important because it is about that it should work.
So, carry over your SD card with music you want to play, and that works. And possibly fine enough.

But settings up something like this doesn't guarantee any good SQ or low jitter. It can be a prerequisite though.
But using the arguments as in that text, and my sensors tell me that ...
Well, without real specs nobody should judge. :nea:
