I tried to run the example program "OpenAL: Playback" after installing OpenAL on Vista. OpenTK 0.9.1 (.7z) from sf.net, downloaded today.
First few runs gives me one-or-two dots ".." before the program exits. There was a short high-frequency noise during those runs.
Then, the third time I double-clicked the example, it played for like ".................." that many dots :) More high-frequency noise, somewhat resembling the falling ring-wav sample played in Windows Media Player, but not really similar.
Any ideas based on this description of the problem?
I'm on a updated Windows Vista Business system running on a HP Pavillion dv2000 laptop.
