[pulseaudio-discuss] Sinks: thread_info.max_rewind debug printfs

[Justin Chudgar]

Here is a slightly better one than the gist I posted last night. Note the 
"update_max_rewind_cb not called!" line. Seems that if a sink is unlinked, 
sink.c sets its max_rewind but; because there is no sink input, it does not 
call the callback.

Is it possible to have an update_max_rewind callback for the sink as well as 
the sink_input? That would seem to make things more consistent and prevent 
different threads from messing with a sink member value.
