The CoolStar SST Audio Driver emerged as the primary solution for this incompatibility, serving as a bridge between the Windows Driver Model (WDM) and the hardware-specific DSP configurations of ChromeOS devices.
After rebooting, check the following:
If you still see a red "X" on the speaker icon, you may also need to install the Realtek High Definition Audio Driver (for HDA-based SST) or Cirrus Logic Awesome Speaker Amplifier Driver (for Surface devices) alongside CoolStar’s SST driver.
