Subject: [Qemu-devel] [PATCH v4 05/14] paaudio: prepare for multiple audiodev
Date: Mon, 19 Aug 2019 01:06:50 +0200
Message-ID: <d43218f327c62cdbd16ea0c922612025fbc4805e.1566168923.git.DirtY.iCE.hu@gmail.com> (raw)
In-Reply-To: <cover.1566168923.git.DirtY.iCE.hu@gmail.com>

Have a pool of refcounted connections per server, so if the user creates
multiple audiodevs to the same pa server, it will use a single connection.  (It
will still create different streams, so the user can manage those streams
separately in pulseaudio.)
