From: Stefan Binding sbinding@opensource.cirrus.com
Cracking noises have been reported on the built-in speaker for certain Bullseye platforms, when volume is > 80%.
This issue is caused by the specific combination of Codec and AMP in this platform, and cannot be fixed by the AMP, so indead must be fixed at codec level, by adding attenuation to the volume.
Tested on DELL Inspiron-3505, DELL Inspiron-3501, DELL Inspiron-3500
