I have my Samsung TV connected to my Macbook Air via HDMI/thunderbolt.
Everything was working just fine until I upgraded to Yosemite (10.10.5).
At the moment, in the "sound" configuration in the "output" tab I don't see anything except internal speakers and I can see the images on the TV but there is no audio.
[I already rebooted, but with no change in behavior.]
Any idea on how to fix this?

If you have the speaker icon in your menu bar, hold down option key and click on the speaker to choose your inputs/outputs.
If you don't see the device you are looking for, go to Launchpad -> Other and look for Audio MIDI Setup. In the bottom left corner you will see a + sign, click on this to add new inputs/outputs for it and then configure them.
If you don't see the device you would like to add, I suggest you start troubleshooting. Remove all the cables there is, switch off and wait, switch on and hold down cmd+R+option+P until it restarts again then release. (resetting PRAM)
