From 55280f24554e4036dfedf764809d53f87bd5126e Mon Sep 17 00:00:00 2001 From: Thierry Bultel Date: Fri, 31 Aug 2018 16:45:44 +0200 Subject: set LIBASOUND_THREAD_SAFE=0 for 4a Since the integration of bluez-alsa support in softmixer, and as warned by the readme of bluez-alsa, there are potential (and effective !) deadlocks in libasound. These deadlocks come especially when uing ioplug PCMs. This hack disables the calls to snd_pcm_lock/unlock in libasound. Notice that the design that consists in using such PCM plugs for communicating with the bluealsa daemon is just a short term solution. When the direct support of bluezalsa communication is integrated in the softmixer, that hack should be removed.
