If you use snd_auto_close_time=0 You don't need to call pjsua_set_snd_dev Samuel > Message du 06/11/08 18:52 > De : "Alexei Kuznetsov" > A : "samuel. vinson" , "pjsip list" > Copie à : > Objet : Re: [pjsip] CPU is up to 10% after pjsua_set_snd_dev() > > I've played a little more and figured out that if I make a call, cpu usage decreases to normal. Here's the program flow: 0. Create pjsua, init with snd_auto_close_time=0, add transport 1. pjsua_start() 2. pjsua_set_snd_dev() -- after that cpu is about 10% If the user leaves the app alone at this stage, it consumes cpu cycles. 3. pjsua_call_make_call() 4. pjsua_call_hangup() or call termination from another party -- cpu back to 0% after that step. I have to call pjsua_set_snd_dev() at program start-up to select appropriate sound device. Is there a procedure to explicitly close the thing that snd_auto_close_time=0 closes after a voice call?

I'm calling pjsua_set_snd_dev() to choose a sound device. For example, user plugged-in a headset, selected it, shut down the app and started it again with the headset plugged-in. I'd like the app to use this headset for sound IO, that's why I call pjsua_set_snd_dev() with appropriate device IDs at the beginning. I don't think snd_auto_close_time=0 could help me in that case. But I do need snd_auto_close_time=0 to auto-close the sound device when idle. The problem was that a sound device did open but did not auto-close after pjsua_set_snd_dev() even if pjsua had been initialized with snd_auto_close_time=0.
