In my case I'm using DaVinci Resolve version 16 on a Windows 7 computer.
For some reason I hear no audio no matter what I do in the application.
In the end the fix in my case was to change device audio properties in Windows, like this:
- close DaVinci and all other applications that could have the audio in use
- From Windows control panel or from the audio icon in the taskbar open the audio control panel.
- Find the icon for the device you are using to hear sound (i.e. internal card, usb headphones and so on)
- click "properties
- tab "advanced"
- in the predefined format box I had "16bit, 44100Hz (CD Quality)" , I changed it to "16bit, 48000 Hz (DVD Quality)
- click "OK" and "OK" again to close all windows
- reopen DaVinci and test, in my case it was now working
bye
