I am having an issue using the simple API since upgrading from 0.9.14 (ubuntu 0.9.04) to 0.9.19 (ubuntu 0.9.10). After quite a bit of debugging, I have been able to at least isolate the problem a little bit. I've confirmed with a few different users that this problem exists and the (really horrible) workaround fixes it. Here's the basics: My application opens an input stream from pulse and then starts a thread to read input from a source. So I'm basically running pa_simple_new() and starting a thread that runs pa_simple_read() until it sees a flag change to tell it to stop. My app has a loop which reads 640 bytes of input from the source and then sends it into a pipe. There is really nothing in between these functions. It's more or less just read 640 bytes and then send to the pipe. Here is the debug output: main input iteration reading 640 bytes from pulse source iteration after 0.000006 seconds reading 640 bytes from pulse source iteration after 0.000014 seconds reading 640 bytes from pulse source iteration after 0.000020 seconds reading 640 bytes from pulse source This shows that I've read 640 bytes of PCM data (at 44.1khz) in 6 microseconds. To preempt the question, no, this is not buffered data. this is consistently reading this way immediately after opening. Now the really weird part is this: If I open up the PulseAudio Device Chooser and open up the volume control app, it immediately starts working as expected. I get about 0.01 seconds of audio (640 bytes of PCM at 44.1khz) and everything is perfect as shown here: main input iteration reading 640 bytes from pulse source iteration after 0.010879 seconds reading 640 bytes from pulse source iteration after 0.010899 seconds reading 640 bytes from pulse source If anyone has any ideas as to what could be causing this, please let me know.
