From 4c64f73c97c7f77426ee838f47fc7bad6a4563b6 Mon Sep 17 00:00:00 2001 From: Jaroslav Kysela Date: Fri, 6 Dec 2019 21:51:47 +0100 Subject: [PATCH] alsa-ucm: parse correctly the device values The UCM library is used to get the fallback values from the verbs and the defaults section. There is no reason to duplicate this code inside application.
