<div dir="ltr">Hi Arun,<div><br></div><div>I'm having an issue where the drift compensation timer event isn't restarting when the sink/source state changes to RUNNING.<br><br>Some information about my set up: I'm using a usb microphone, my speakers are plugged into a usb sound card, and I'm running Arch Linux. The application that I'm using the echo cancel source/sink with is Mumble.<br>
<br>Implementing the above patch fixed it, but now that you mention the state change callbacks (to be quite honest I didn't look into those at first, I'm fairly new to pulseaudio), I'll debug it more this week to see what's going on.<br>
<br>I'm not quite sure what to say when it comes to steps to reproduce. It's a persistent problem I'm having. Start pulseaudio, load the echo cancel module, start Mumble with the echo cancel source/sink set to default. I threw a pa_log_debug into time_callback, and when I check my pulseaudio log, I only see that debug info once, when the source/sink is first created.<br>

</div>The timer is already restarted when the sink or source state changes<br>
to RUNNING (see the state change callbacks a little later on), so this<br>
patch should effectively be a no-op.<br>
<br>
Could you describe the problem you're seeing and possibly steps to reproduce it?<br>
<br>
Cheers,<br>
Arun<br>
