Hi Colin
I changed the sample role from proplist in play_beep( ) below:
static void play_beep(pa_core *core)
{
uint32_t idx;
pa_proplist *pl = pa_proplist_new ();
pa_proplist_sets(pl, PA_PROP_MEDIA_ROLE, "test");
pa_log ("DBG: %s: %d\n", __func__, __LINE__);
pa_scache_play_item(core, "beep", "alsa_output.hw_0_0", PA_VOLUME_NORM,
pl, &idx);
}
Here are the logs for segmentation fault:
