Ok, i did some testing. First i built and installed sdl (p9) without the aforementioned patch, recompiled ioquake3 and could play ca. 30 min. with perfect sound. I then applied the 3rd chunk of the patch, rebuilt and installed sdl, rebuilt ioquake3 and could play another 20 min. Then some slight stuttering occured again. I will test some more over the week if time allows. Alf
