From d84489e374f5b9b3ab424a5169e68e06a4329524 Mon Sep 17 00:00:00 2001 From: Connor McAdams Date: Fri, 11 Dec 2020 17:55:03 -0500 Subject: [PATCH] ALSA: hda/ca0132 - Add ZxR surround DAC setup. Add pre-dsp download initialization for the DAC's used in the surround sound configuration. Fixes issues of no audio on surround channels.
