Could it be uhd@60 consumes all the bandwidth and there is no place left for the sound transmission? Otherwise, this works great (mbp mid-2015 iris, adapter 7.23, sammy uhd tv).
No sound at uhd@60, works @50

Hi Vojislav, sounds should also work …
please check if there is a driver update aivailable for the Graphics Card, often there is also UHD sound driver in those Driver packs.
Some feedback …
Make sure your MacBook is post mid 2010, the earlier MacBook models do not support audio output through its mini DisplayPort.
System Preferences > Sound. There are 3 tabs in the window; Sound Effects, Output and Input. Be sure you are on the Sound Effects tab. Middle of the window select your TV where it says “Play sound effects through:”.
Select the middle tab named Output.
Select your TV from the drop-down list next to HDMI, below where it says “Select a device for sound output”.
Using either Finder or Launchpad go to Applications > Utilities > Audio MIDI Setup.
On the left-hand side of the window you should now see HDMI. In the middle of the window, on the Output tab, where it says “Source:” select your TV from the drop-down list.
If you CANNOT see a speaker icon next to HDMI in the list on the left, do the following:
Bottom left of the window select the wheel icon with the down-pointing triangle. Make sure that sound output is selected and that you can now see a speaker icon next to HDMI in the list of devices.
If you still cannot hear sound, Turn everything off , power tv first and then Mac.
