From 683e212a779341a7b376fbb6d5df54cb8205893d Mon Sep 17 00:00:00 2001 From: Stefano Pigozzi Date: Thu, 3 Oct 2013 23:38:19 +0200 Subject: ao_coreaudio: clear output buffer on buffer underrun Output silence to the output buffer during underruns. This removes small occasional glitches that happen before the AUHAL is actually paused from the `audio_pause` call.
