The forum

Hello all! Just a query, I'm pretty new to all this. I've just downloaded Playonmac and started on one of my favourite games from the Steam library to check it worked ok. It did! However I can't hear a thing! No sound at all. I checked that it was meant to be coming out of the mac speakers and looked in options on the game but everything was working there, just not actually pumping out any of the sound itself. 

My mac is a Macbook Pro 2019, 2.4 GHz Quad-Core Intel Core i5, graphics card Intel Iris Plus Graphics 655 1536 MB

Any help would be wonderful! Thanks in advance!
