 3. SIGILL (signal 4) or other fault at loading l3codeca.acm:
   Problem: shared libs are loaded to 0x00xxxxxx instead of 0x40xxxxxx

 Various A-V sync and other audio problems:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 General audio delay or jerky sound (exists with all or many files):
-- bad select() in audio driver (including ALSA's OSS emulation)
-  Workaround: ./configure --disable-select
-  SOLVED: using ioctls instead of select in the new audio code
-- audio buffer problems
+- audio buffer problems (buffer size badly detected)
   Workaround:  mplayer -abs option
-  SOLVED: using ioctls in the new audio code
 - slow machine (cpu or vga)
   try with -vo null, if it plays well, then you have slow VGA card/driver:
   Workaround: buy a faster card or read DOCS/VIDEOCARDS about how to speed up
