Slackware :: Either O.S. Or MPlayer Is Wrong.

Linux 2.6.21.5, GNU (Slackware 12.0)
MPlayer 1.0rc2-4.1.2

Although mplayer is not a part of the Slack distros, I think the issue is more in connection with the system setup and thefore I place this post in this forum. What is it with mplay- er? I've installed and reinstalled slackware 12.0 many times. And each time I have built mplayer from the sources and it has run fine. In the one before the last slack 12 installation, with subsequent building and installation of MPlayer, some- thing went wrong. And the same can be said of the present installation. Every source mplayer reproduces, it does it fine, with the exception of CD-ROM. No matter the CD-ROM I insert (I have them of the highest quality, bought out of the shelf) or the CD-ROM unit I use. The result is always the same: the sound is faulty, as if the machine had not enough speed. And I repeat. MPlayer played CD-ROMs fine in the past and under the same conditions. Or almost the same conditions, because something must obviously have changed.

Some additional data:

(a) Window$MediaPlayer plays them fine on the same machine.

(b) I invoke it from the physical console.

(c) KsCD under xfce plays them fine.

(d) I am able to load an o.s. from both CD-ROM units on the machine. All the more so, should audio be "correcty" read off the CD.

(e) Now I remember the last time I compiled mplayer with GUI support.
