From b878413c626a6797d382ae4abed4c3f417eed2bd Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 8 Jun 2020 22:21:41 +0200 Subject: [PATCH] bytcr-rt5651: Fix high noise level + soft input on DMIC The DMIC needs to have the DMIC ASRC enabled, otherwise capturing audio from it results in mostly capturing noise + the actual recorded voice very soft in the background of the noise. This has been tested on a Point of View P1006W v1.0 tablet, which is the only RT5651 X86 device using a DMIC that I am aware of.
