  - MPlayer is mostly intended for OSS
  - use at least 2.4 if possible, 2.2 isn't tested
+ - In case of any problems, first try to change "#define HAVE_AUDIO_SELECT" to
+   "#undef HAVE_AUDIO_SELECT" in config.h , and recompile!
+   (make distclean ; make)
+   Your soundcard may not support querying of its buffer.
  - if sound clicks when playing from CD-ROM, turn on IRQ unmasking !
    for example "hdparm -u1 /dev/cdrom" (see "man hdparm" !!!)
+   This is also recommended anyways... (for XMMS, etc...)
  - don't use your soundcard by other application ( for ex. XMMS ) !
    if you use ESD, start MPlayer with the esddsp utility !
+ - Please tell us how MPlayer and your soundcard(s) worked together!
