From 6dca7d95032aea6a07c1a28edddfba0cc33b11f9 Mon Sep 17 00:00:00 2001 From: Libin Yang Date: Wed, 15 May 2019 13:50:23 +0800 Subject: [PATCH] ASoC: intel: skl_hda_dsp_common: create HDMI jack kctl This patch call snd_jack_add_new_kctl() to create the HDMI jack kctls. Userspace needs these kctls to detect the hdmi monitor hotplug. In /usr/share/alsa/ucm, the config file needs to assign a jack kctl to "JackControl" to let PA get the jack hotplug status.
