From: Johannes Schickel <lordhoto@xxxxxxxxx> [ Upstream commit 5762f980ca10dcfe5eead7c40d1c34cae61f409b ] The USB audio device 0db0:419c based on the Realtek ALC4080 chip exposes all playback volume controls as "PCM". This is makes distinguishing the individual functions hard. The added mapping distinguishes all playback volume controls as their respective function: - Speaker - for back panel output - Frontpanel Headphone - for front panel output - IEC958 - for digital output on the back panel This clarifies the individual volume control functions for users.
