`scarlett_yaml`

Script for dumping a Focusrite Scarlett's internal mixer configuration to YAML, and loading it back again.

This is important on Linux for two reasons:

one cannot run Focusrite's MixControl app (even under Wine or in a Windows VM)
the configuration changes made via ALSA's amixer are not persisted to the interface's flash storage, which means the configuration is reset to the factory / last saved values on a power cycle.

Usage

Dump to standard output:

Dump to a file

Load from a file:

TODOs

[ ] Normalize command-line handling for the script (e.g., add an

arg parser, support dumping to a file directly, support loading from standard input, etc.)
[ ] Capture additional ALSA information (e.g., output gain channel names,

parameter read-write / read-only status, etc.) See the output of amixer -cUSB contents.
[ ] Extract the data model from the script into a separate, importable

module.
[ ] Write some kind of GUI? Probably YAGNI for me: the dumped YAML

is enough for my usecases (I'd rather edit text than use the mouse to tweak hundreds of sliders / knobs, e.g. in qasmixer.
