Reinstalling the Realtek audio drivers fixed the 'audio not working when switching from USB to builtin Surface Book 2 speakers' problem, could this also explain my May 27, 2019 audio issue?
Pontifications
- See May 17, 2019: USB Audio didn’t work but USB microphone did. Vidyo problem? Hardware problem with Surface Book 2 USB?
- So krazy! Never had audio issues like this with multiple MacBooks over the last 15 years!
