you should ask PA developer to add code to debug since this is a queue used
by PA and has no relationship with alsa ,
alsa-sink and alsa-source can only post PA_CORE_MESSAGE_UNLOAD_MODULE
modules/alsa/alsa-sink.c: pa_asyncmsgq_post(u->thread_mq.outq,
PA_MSGOBJECT(u->core), PA_CORE_MESSAGE_UNLOAD_MODULE, u->module, 0, NULL,
NULL);
modules/alsa/alsa-source.c: pa_asyncmsgq_post(u->thread_mq.outq,
PA_MSGOBJECT(u->core), PA_CORE_MESSAGE_UNLOAD_MODULE, u->module, 0, NULL,
NULL);
and you have to copy definition of struct asyncmsgq_item from asyncmsgq.c
void pa_asyncq_post(pa_asyncq*l, void *p) {
struct localq *q;
+ struct asyncmsgq_item *i;
pa_assert(l);
pa_assert(p);
+ i=( struct asyncmsgq_item *)p;
if (flush_postq(l, FALSE))
if (pa_asyncq_push(l, p, FALSE) >= 0)
return;
/* OK, we couldn't push anything in the queue. So let's queue it
* locally and push it later */
if (pa_log_ratelimit())
- pa_log_warn("q overrun, queuing locally");
+ pa_log_warn("q overrun, queuing locally code %d",i->code);
