No other applications are using audio at the same time. If you do try to play to the same sink with some other application, for example paplay, while your own application is stuck in pa_simple_write(), does that other application work? I don't see any other reason for pa_simple_write() getting stuck on a running sink than the sink getting stuck. What kind of sink is it? Alsa? -- Tanu
