| Issue | Potential Solutions | | :--- | :--- | | | Verify the correct output device; perform a REFRESH-POWER reset; ensure no other audio drivers are conflicting; reinstall drivers following the guide. | | Audio Stuttering (e.g., in Zoom) | Typically a driver limitation with the fixed 16-bit, 48kHz output format. Reporting specific apps to the developer may help. | | Driver Fails to Start (Code 10) | Often tied to digital signature enforcement. Re-verify testsigning mode is on and Secure Boot is off. | | No HDMI Audio Output | Related to Intel Display Audio driver or GPU settings. Check device manager for "Intel Display Audio" and set it as the default playback device when connected via HDMI. | | Switcher App Not Working | The utility may not work reliably with all hardware. Manual switching is an option. | | Windows Version Compatibility | Check the supported Windows version (e.g., Windows 10 22H2 is often safe, while newer 25H2 may be less supported). Latest Windows 11 updates are generally okay. |

The hardware on many of these devices, particularly those using Intel's Smart Sound Technology (SST), requires a specialized "shim" to be recognized and used by Windows. In the simplest terms, the driver acts as a translator, converting Windows' generic audio commands into a language the Chromebook's specific audio hardware can understand. coolstar sst audio driver new download
