Hello everyone! A follow-up to the problem I have: Reimar D?ffinger replied with a concise answer to the problem on the mplayer-users mailing list: http://lists.mplayerhq.hu/pipermail/mplayer-users/2010-May/079933.html ... which is fun to read. Thanks Reimar :) Any further expert opinions on this matter? I wouldn't like to go through hoops of compilation fun to get a working OpenAL / MPlayer. If I am not mistaken, this bug is known at Ubuntu.
