From 587631a15be09c27cae3ceb1ae0de2ff17b9b8f1 Mon Sep 17 00:00:00 2001 From: Stephane Fontaine Date: Fri, 24 Jun 2016 18:17:20 +0400 Subject: [PATCH] Add native support for pulseaudio. (#283) * Add native support for pulseaudio. This adds ability to get Pulseaudio current volume without calling an external program. Also it provides a few other parameters like card's current profile similarly to pavucontrol. Currently it only queries the default sink (and associated card). * Switch to pulse async API. This us by far the most efficient as conky subscribe to a few pulseaudio notifications. Whenever pulseaudio server changes (volume or default sink or default card), conky's callback updates the results. --- cmake/ConkyBuildOptions.cmake | 2 + cmake/ConkyPlatformChecks.cmake | 6 +
