Using gdb is a good idea, it will probably be effective at finding the looping part of the code. Regarding logging, I meant adding new log statements to the pulseaudio code. With -vvvv the log verbosity is already at the maximum, so the current logging isn't sufficient to find the looping code. -- Tanu https://www.patreon.com/tanuk
