This is a backport of recently upstreamed fix for XPS 9530 sound issue. Both apply cleanly to 6.8.y, and could also be cherry-picked from upstream.
Ideally should be applied to all branches where upstream commit d110858a6925827609d11db8513d76750483ec06 exists (6.8.y) or was backported (6.7.y) as it adds initial yet incomplete support for this laptop. Patches for 6.7.y require modification, will be submitted separately.
