If CPU is distracted by other tasks other than shuffling packets from Jitsi to soundcard, soundcard won't have enough data to playout the audio which results in buffer underrun. The higher the latency = higher playout buffer = lower chance of buffer underrun. The lower the latency = lower playout buffer = higher chance of buffer underrun. kel
