@john-phd Hey man, thanks for this topic.

I also got this problem today after I restarted my PC. I never had problems with sound before (Win7+external USB sound card). Sound works in other programs like Windows, Winamp, VLC.

Solution That Worked :

• Add these commands --disable-features=AudioServiceSandbox --disable-features=AudioServiceOutOfProcess
  to the shortcut path. Done.

What I Tried:

• Disabling unused audio devices
• Routing the sound through a virtual cable
• Installing a fresh copy of Opera

You are a legend!!! Finally I can listen proper audio on YT. It's amazing ... +/-20dB, that's fantastic. Only bug is at start only one speaker works but after moving the L/R balance it worked for both speakers.

The problem is still present. :((

How could I know? I just found that out! It worked for me ... .

I just did something I read in another topic. Disable all Extensions, close the browser, start the browser and enable them again. This seems to fix it.

Same problem here!
