Subject: [PATCH 0/2] ALSA: usb-audio: scarlett2: Read all configuration at init time
Date: Sun, 6 Jun 2021 23:46:44 +0930	[thread overview]
Message-ID: <cover.1622974661.git.g@b4.vu> (raw)

These two patches add support for reading the mixer volumes and mux
configuration from the hardware when the driver is initialising.

Previously the ALSA volume controls were initialised to zero and the
mux configuration set to a fixed default instead of being initialised
to match the hardware state.

The ALSA controls for the Scarlett Gen 2 interfaces should now always
be in sync with the hardware. Thanks to Vladimir Sadovnikov for
figuring out how to do this.

Takashi, if these pass your review, I believe that they are
appropriate for:
