These tools are used for troubleshooting sound issues with Realtek chipsets on Linux.
This tool takes output dumped from a specially modified version of QEMU and removes unnecessary output to leave only Realtek amplifier coefficient verbs passed through to a sound card connected via VFIO.
Usage: python3 ./cleanverbs.py output-from-qemu-file
For more information on how to get this QEMU output in the first place, check my tutorial.
This tool takes output from cleanverbs and applies each verb to the sound card.
Usage: python3 ./applyverbs.py output-from-cleanverbs [-d]
The -d flag gives more verbose output and also adds a delay so you can see which verbs are necessary to activate the speakers.
