I'm using DUMB library for background music (it uses 
get_audio_stream_buffer) and all the music code works in its own thread. 
  But sound is initialized in the main thread and sound effects are 
somtimes played from the main thread using play_sample function.

Looks like there are some problems with this approach in Linux. After 
playing music for some time in a loop, the game just starts making noise 
and becomes unresponsive. Time needed to wait before this problem shows 
up varies from about 15 minutes to several hours.

I will try to make a smaller testcase and experiment with it.
