Here is the configuration:
iMac > USB Audio System > Headphones
Conditions that work:
Youtube (tv) content provides audio to the above configuration using Firefox or Safari.
Conditions that don’t work:
Youtube (tv) content audio does not work when using Brave or Chrome browsers with the above configuration.
If I change the Output device on the iMac from the USB device to “Internal Speakers”, audio is heard.
Steps I have taken to resolve:
- Upgraded and re-installed Brave and Flash.
- Verified that Flash and Sound are “Allowed” on the pages that I am connecting to.
- I have disabled all of the extensions and re-enabled them with no success.
This appears to be a fundamental flaw in the design of Chromium based browsers at this point.
Any steps to get this working would be deeply appreciated.
