Which audio license should I purchase for Lenovo C13 Yoga (Morpheus)?

Hi again,

I’ve confirmed that my Code 10 issue is due to a missing license. I am ready to purchase it, but I want to make sure I buy the correct one for my specific hardware to avoid any mistakes.

My Device Details:

  • Laptop: Lenovo ThinkPad C13 Yoga Chromebook (Morpheus)

  • CPU: AMD Ryzen 5 3500C (Picasso)

  • Firmware: MrChromebox-2512.2 (01/25/2026)

  • Hardware ID for the “Code 10” device: ACPI\VEN_AMD&DEV_33D6

My question: On the CoolStar website/Patreon, which driver license should I choose for this laptop?

  1. Is it the “AMD Audio Co-Processor (ACP)”?

  2. Or do I need the “AMD SOF Audio” license?

  3. Do I also need a separate license for the Realtek/Maxim codec, or does the ACP license cover everything needed for internal speakers to work?

I want to get the internal speakers and microphone working. Please let me know which option is the right one for Morpheus.

Thanks!

there is nothing to buy for AMD Picasso platform devices, the ACP audio driver is not licensed.
