This Alsa/AC3 desync problem is easy to fix: Use Alsa 0.9 (rc5 or newer)
and the mplayer option "-ao alsa9:mmap:noblock"

But don't use that "mmap:noblock" flags when not using -ac hwac3 - this
doesn't seem to work well (choppy sound).

Why would you want this? You can tell ogmtools with the "--noaudio"
flag to just ignore that unwanted part...
