From 18e2c1771b693fd55d5f5967e20ef075a19d4667 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?K=C5=91v=C3=A1g=C3=B3=2C=20Zolt=C3=A1n?= Date: Mon, 19 Aug 2019 01:06:55 +0200 Subject: [PATCH] audio: do not run each backend in audio_run MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit audio_run is called manually by alsa and oss backends when polling. In this case only the requesting backend should be run, not all of them.
