File 0004-alsa-mixer-autodetect-the-ELD-device.patch of Package pulseaudio.24379
From 72fa468a45031ba4be4d24d70fddf282b5c9da66 Mon Sep 17 00:00:00 2001 From: Tanu Kaskinen <tanuk@iki.fi> Date: Sun, 8 Oct 2017 19:48:26 +0300 Subject: [PATCH] alsa-mixer: autodetect the ELD device This removes the need to hardcode the ELD device index in the path configuration. The hardcoded values don't work with the Intel HDMI LPE driver.
