What do you think? Well, I did not think about the exact message being hidden. I only noticed that the enum did not use the = PA_SOURCE_OUTPUT_MESSAGE_MAX. But of course, you are right. So here is an alternative commit message, please use it if you like it better. loopback: don't use 0 for custom source output message id Message id 0 is PA_SOURCE_OUTPUT_MESSAGE_GET_LATENCY. So, every time PulseAudio sent PA_SOURCE_OUTPUT_MESSAGE_GET_LATENCY message to the loopback source output, it actually hit the SOURCE_OUTPUT_MESSAGE_LATENCY_SNAPSHOT handler instead. As a result, the SOURCE_OUTPUT_MESSAGE_LATENCY_SNAPSHOT handler was called when not intended, the default PA_SOURCE_OUTPUT_MESSAGE_GET_LATENCY handler was not called at all, and the latency was thus evaluated incorrectly.
