Confirmed. And, here are some more (if you find any more, please post links):

It's a known issue (DNA-74703) and why the audio cuts out is known.

For me, the audio in the links:

Doesn't work
Works
Deleted
Works
Works
Works

Works

The ones that work all worked immediately first time. They're all from mobile and they all look like reuploads - as in they were downloaded from the original poster's account rather directly uploaded from the app that recorded it. This could contribute to more compression of the video files and also stripping out multiple audio channels down to just 2 channels (would have perhaps even forcing 2 channels only (or even mono channel) thus fixing any issues - I say this because they worked for me for some reason).

Though, unlike the Bugzilla report on Firefox for this problem, this all sounds like it is more than just a multiple channel problem in Opera. I'm not even sure multiple channels are the issue for Opera.

I'm really curious to see if this problem is present in videos not recorded/edited/encoded/uploaded from mobile, like a trailer or a meme uploaded from a computer to Twitter or wherever.

Here are the only flags I have toggled (not that they work properly anyway, overlay scrollbar is still broken - also just noticed that taking screenshots of the flags page cuts the image in half... we're just stumbling across bugs left and right at this point ):

Here are my Windows Performance Options (which also should have no affect):

Here are my Opera settings that have worked for some when changed (mostly Chrome users?), for whatever reason (makes no difference to me, nor even sense why it would change anything) (my ad blocker is turned on):

Here are my 3 Opera extension that are enabled (extensions page also does not work well with screenshot tool):

The only solution I've read here so far is making the video full screen to hear all the audio. Not an ideal permanent solution.

Interesting that you get different results.

As for your settings in Opera and Windows, I don't think they matter.

With https://twitter.com/ShyCountryCutie/status/1104993101028896768 for example, switching to full screen does make it play. However, it never gets louder at 9 seconds (in Chrome either) like the non-full-screen version. Twitter probably sends the video in a different way which doesn't present the problem.

Yeah, not sure. I did ask a few Twitter users if the increased loudness in Chrome at 9 seconds is intentional or not. Still waiting for replies. It could be Twitter is boogering them up.

@luca786toni Same here, they really need to fix this annoying bug.

@silaz Do you have any links that show the problem?

silaz

silaz @burnout426

@burnout426 Well, just use Opera and go on Twitter. If you shouldn't have the same issue like all the other people, I can upload a video to YT or something.

@silaz I was hoping to gather specific links on Twitter to gauge how abundant these problem videos are.

@burnout426 I can say it's getting worst. At first it was maybe 2-3 videos a day that had this problem but now most of the videos I saw on twitter has this.
If you wanna compare two here is a link.

Length : 56 seconds,audio is gone after 9 seconds
https://twitter.com/erdalbiroll/status/1116473516684132352

Length : 44 seconds, audio is perfectly fine
https://twitter.com/Red_ZaZa_/status/1116575919215276033

Edit: Also the fullscreen solution works.When the video is fullscreen, audio spikes up at 9 second so it is either a problem about how opera handles .ts file extension or how Twitter streams these.If you go fullscreen before 9 seconds you can turn it back to normal and it works fine.

The first video is screencaptured on a mobile (iPhone), also horizontal.
The second video is landscape (manually pillarbox'd), possibly from a computer.

It seems the theory that the problem is with mobile recorded/processed/uploaded videos is looking true.

I'm curious to see if we can come across some landscape/horizontal videos with the audio problem.

Some more that show the problem for me.

The audio cuts out at 9 seconds (for all of them) and then comes back for the last 2 seconds (on some of them).
Only the last one worked for me without dropping audio, but the audio did jump at 9 seconds for the remaining 2 seconds of the video as the length of it was 11 seconds in total.
I guess if the video was 12 seconds long instead of 11, then the 10th second would have dropped out? This seems to be the pattern.
Also all of these are mobile videos again (not sure of the operating system but I'll guess it's iOS if they're using TikTok + their age). The operating system is the next thing to find out here and also if any landscape mobile videos have this problem too (still looking for computer uploaded videos too).

Edit: At the time of writing this Twitter is flooded with videos of the Notre Dame cathedral fire. All landscape mobile videos seem to be working fine, but some vertical videos aren't. I'm not sure if it's because people are downloading them and reposting them (so Twitter reprocesses the video's audio) or if it's because of the OS the video came from.

I tweeted @Twitter about this forum thread. No response as of yet.

Ok i'm done waiting for a fix. Been using Opera for years now but it bothers me to open another browser just to watch twitter videos. I'm switching to firefox now

@Username2 Agree with you this is horrible.

Still not fixed.

luca786toni @anamelash

@anamelash I can't remember when it was fixed but it's been at least a year.

In April 2019 when I had the problem, I was on:
Windows 10 Edu (1803) 64-Bit
Opera 58.0.3135.127
WidevineCDM 4.10.1196.0

Now in November 2020, I'm on:
Windows 10 Edu (1909) 64-Bit (unable to receive 2004 and 20H2 updates yet)
Opera 72.0.3815.207
WidevineCDM 4.10.1610.0
