From 4413665dd6c528b31284119e3571c25f371e1c36 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jan=20Sch=C3=A4r?= jan@jschaer.ch Date: Tue, 29 Oct 2024 23:12:49 +0100 Subject: [PATCH] ALSA: usb-audio: Add quirks for Dell WD19 dock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
The WD19 family of docks has the same audio chipset as the WD15. This change enables jack detection on the WD19.
We don't need the dell_dock_mixer_init quirk for the WD19. It is only needed because of the dell_alc4020_map quirk for the WD15 in mixer_maps.c, which disables the volume controls. Even for the WD15, this quirk was apparently only needed when the dock firmware was not updated.
