I wrote a super-simple test using the pa_simple API. I have some sound data in a static array. I call getchar(), and then call pa_simple_write, in an infinite loop. When I run this, and just hit enter several times, I expect to hear the sound played once each time I press enter. Instead, it plays nothing the first time, but then plays it twice the second time I press enter, nothing the third time, twice on the fourth and so on.
I ran this in gdb, and saw something super-strange. The first two times pa_simple_write was called, no sounds was played. However, when the next call the getchar() was made, both sounds played! Somehow getchar() is interacting with the sound queues! I ran this test in Ubuntu Karmic. Can anyone else confirm this strange behavior? If nothing else, I'd love to find out if this is Ubuntu specific. I've attached the source code. Just type 'make' in the keyspeak directory. Thanks, Bill
