How do I fix ErrorState::Enter unknown error code 21048?

This error may occur on the SUT when testing with MobileMark 2018, MobileMark 25, SYSmark 30 if the system does not have an audio driver installed and an audio device such as headphones, or speakers connected to the SUT. Note that Bluetooth devices may not be sufficient as the SUT may place them in a low power mode or disconnect them completely in order conserve energy.

To avoid this error, please install an audio device driver and connect an audio device to the SUT prior to installing and testing with BAPCo benchmarks.
