This issue has been going on for ~4-5 months now
Basically, sound will drop out during youtube video, usually for 2-3 seconds, then the video freezes and the unplayed audio will play to 'catch up', and then it will continue.
I've tried using extensions to force Flash player,
I've removed ALL extensions and reset Opera to default, and same problem persisted. Uninstalled and re-installed, and the problem persisted.
i've tried changing audio-playback devices (i have an external sound interface with analog and digital outs, as well as onboard-audio),
i've tried updating / backdating graphics drivers, removing potentially-conflicting audio devices in device manager, updating Windows, etc. but the same problem persists regardless.
If i use Firefox or Edge, the problem simply doesn't exist. It is solely w/ Opera. Which is frustrating, because otherwise its my favorite browser.
Am pulling out my hair on this.
Does anyone experience similar problems? and is it recent, or older? All the info i've seen in the forums tends to refer to older problems w/ Youtube, but nothing like this in the last 6months or so.
Would be interested in hearing any suggestions. Thanks.
