Unfortunately, sometimes, users face issues with sound. HDMI can transfer uncompressed video data or condensed or uncompressed digital audio data from HDMI-obedient appliances to a compatible system. I have a feeling one of these will solve the problem.High-definition Multimedia Interface (HDMI) is useful for your MacBook, as it allows you to hear audio. Try a different HDMI cable if you've got one. You might try another HDMI input on your TV just as a test. Maybe that input port on your TV is pre-set to expect only separate stereo jacks on that input. Light up the menu options on your TV, and just double check your Audio options settings.

You should see the speaker icon next to that audio output selection too. Select your thunderbolt output and make sure the volume sliders are turned up.

If you have various sound drivers installed and showing up in Audio MIDI Setup, just leave them alone for now, and DO NOT use any aggregate devices. Make sure your system volume is turned up there too. Try setting your "Use audio port for:" to Sound Input, as it may be hogging the audio out channel and not letting your thunderbolt use it. Go to your MIDI Audio Setup again and make sure that your thunderbolt output is set to "Use this device for sound output."
