Subject: [PATCH 2/2] ALSA: hda/ca0132 - Add ZxR surround DAC setup.
Date: Fri, 11 Dec 2020 17:55:03 -0500 [thread overview]
Message-ID: <20201211225504.4508-2-conmanx360@gmail.com> (raw)
In-Reply-To: <20201211225504.4508-1-conmanx360@gmail.com>
Add pre-dsp download initialization for the DAC's used in the surround
sound configuration. Fixes issues of no audio on surround channels.
Fixes: 2e492b8ee5da8 ("ALSA: hda/ca0132 - Add ZxR init commands")
