[PATCH v1 3/4] ALSA: hda: cs35l41: Support HP models without _DSD using dual Speaker ID

From: Stefan Binding
Date: Fri Jan 26 2024 - 06:30:45 EST


Laptops 103C8C66, 103C8C67, 103C8C68, 103C8C6A use a dual speaker id
system where each speaker has its own speaker id.
The generic configuration table doesn't support this, so it needs its
own function.
