There was another post on this list recently comparing pulse version 9 to 15 from someone with an email at the same domain. I'm guessing that more than just the pulse version has changed in your comparison. I had a look at the assertion that's firing, and none of the code in that area has changed between pulse version 9 and 15. What seems to be happening in the code is that ALSA reports that sufficient buffer space is available, then returns EAGAIN when pulse tries to write into that buffer. This shouldn't happen, hence the assertion. Can you try running pulse with the log level set to debug and report the output? There's a condition in the code where a buffer size is guessed at instead of trusting the returned value from ALSA, and there should be a corresponding log message for this. --Sean |
