Subject: [PATCH v7 10/11] darwin: detect CoreAudio for build
Date: Fri, 22 Jan 2021 12:11:12 -0800	[thread overview]
Message-ID: <20210122201113.63788-11-j@getutm.app> (raw)
In-Reply-To: <20210122201113.63788-1-j@getutm.app>

On iOS there is no CoreAudio, so we should not assume Darwin always
has it.
