Hello,
Suppose I have cheap onboard soundcard and cheap speakers, two different
music players (for example mpd and mplayer) with the same output
interface (both using alsa or both using oss compatibility layer), no
resampling, filters or anything, with dmix disabled and no other
software mixers. Is it normal (or possible) that for the same audio
files each player will produce noticeably different (in terms of
quality) sound? In other words, does the choice of music player have any
impact on final sound quality?

Uh oh, here we go again! The inevitable DAW sound quality discussion I
regularly see on the KVR forums.
Honestly, there's no difference in sound quality between applications, it
depends entirely on your soundcard and speakers.

If the data is identical: No.
If you play back compressed data, and the players use different methods
for uncompressing/reconstruction, the resulting PCM stream may differ.
And then you *may* hear a difference.

one version of this library installed, is it enough to assume that the
results will be the same?
And the difference you mentioned, can it be picked up by an untrained ear?

We don't want to assume, we want to know. Grab the output and compare it.

If you actually experience something like that, make sure that the
levels are really the same, otherwise any comparison is flawed.
