No sound from MacBook Pro following HDMI connection to TV

I've repeated these steps several times;

  1. Restart MacBook Pro - sound works ok.
  2. Connect MacBook to TV via USB-C Digital AV Multiport Adaptor and high-grade gold HDMI cable.
  3. Sound works ok on TV.
  4. Disconnect adaptor from MacBook
  5. At some time later, play play back voice memo, watch YouTube, etc. NO SOUND.
  6. Check everything as per Apple Support: https://support.apple.com/en-gb/HT203186 - still no sound.
  7. Restart MacBook - sound OK


Anyone have any idea why, after connecting MacBook to TV through Digital AV Multiport/HDMI cable, sound does not work on MacBook until after a reboot?

Hi,

Resetting NVRAM could solve the sound issue.
