If a song or sample has played for any amount of time, the OpenAL thread starts eating my CPU whenever audio is not playing.

It uses an order of magnitude more CPU when idling than when playing. One would expect it instead to idle instead.

Gosu version: 0.7.40
OpenAL version: openal-soft 1.13
OS: Debian testing (haven't tested other systems)

Reproduce using:

#include <Gosu/Gosu.hpp>

class Win : public Gosu::Window
{
public:
  Win()
    : Gosu::Window(320, 240, false),
      song(L"foo.ogg"),
      frames(0)
  {
    song.play();
  }

  void draw() {}
  void update()
  {
    if (frames++ == 60 * 2) // 2 seconds
      song.stop();
  }

private:
  Gosu::Song song;
  int frames;
};

int main()
{
  Win w;
  w.show();
  return 0;
}
