No Sound - SiriusXm with Opera browser on Ubuntu/Mate 20.04

Hello, now that i just upgraded from Ubuntu/Mate 18.04 to 20.04 ...
Running Opera web browser with SiriusXm web site/player no longer works. Sirius will now only play audio (on 20.04) with Chrome.

Ps. Downgrading to previous Opera versions has no affect

I just upgraded a second box to 20.04 (from 18.04) and sure enough Opera will not play SiriusXm.

Something with 20.04 broke Opera with Sirius as well as other sites like ""
Ideas anyone ??

UPDATE: Upgrading to 20.10 now to see if that fixes anything...
CONCLUSION: Opera audio & video as listed in post still broke - gonna have to go back to 18.04.

On my Thinkpad test machine the sound was being directed to the docker. Every time I rebooted, I had to manually change the sound preferences back to the laptop from the docker. For some reason, the laptop never remembered my choice of sound output in Ubuntu mate 20.04 and 20.10.

That's interesting, I'll have to watch out for that.

GOT IT .... Found a posting on some Opera blog/support site -- that the "" file that comes with opera is broken. One of the fixes listed is to use ffmepg from chromium.

so to fix Opera for Ubntu 20.x - I had to

  • sudo {or become root}
  • mkdir /usr/lib/x86_64-linux-gnu/opera/lib_extra
  • snap install chromium-ffmpeg
  • find / -name
  • looked/made note of newest chromium ffmpeg version from the "find"
  • cp /snap/chromium-ffmpeg/17/chromium-ffmpeg-98516/chromium-ffmpeg/ /usr/lib/x86_64-linux-gnu/opera/lib_extra

Relaunched Opera -- tested Sirius XM and p___hub -- it works!
