Issue Details

Steps to reproduce:

1. Watch any stream that you'd get ads on.
2. When the ads happen (you can sometimes know because bots or people tell about it, etc): The ad does get blocked, but audio issues happen

Expected Behavior

You should hear the audio of the stream normally while the ad is being blocked.

Actual Behavior

While the ad is blocked, it seems that the player does not get proper audio anymore?

Because what happens is that during an ad, you'll hear the audio just breaking up into a loop of some seconds (I assume some buffer value?).
Imagine the last 10 seconds or so of audio before the ad just looping - but the image part of the video continues just fine.

It is highly irritating.

Reloading the stream during that period will just cause a new ad break for you - which AdGuardExtra will block, but the audio loop issue just repeats.

Sitting through the ad period, unfortunately audio is not restored to normal once the ads would be over.
Once this bug hits (and it hits every time an ad gets blocked), your audio is messed up for good.

The only "fix" I found is estimating when the ad is over and then reloading the stream.

Screenshots

This is an audio issue. Screenshots wouldn't be all that helpful.

Hello,
Unfortunately I'm not able to reproduce it.

When the ads happen (you can sometimes know because bots or people tell about it, etc): The ad does get blocked, but audio issues happen

There is indicator in top left corner of the video player that ad is blocked (Blocking ads), do you see it?

Could you please provide information what exactly version of AdGuard Extra Extension do you use?
Do you use any other extensions?

There is indicator in top left corner of the video player that ad is blocked (Blocking ads), do you see it?

Yes. I also see the usual video quality going down during ads.

Could you please provide information what exactly version of AdGuard Extra Extension do you use?

AdGuard Browser extension
Version 5.4.3.1

And
AdGuard Extra (Beta)
1.1.35

Do you use any other extensions?

Only 7TV.

[AdamWr]

Could you please check if issue occurs with 7TV extension disabled?

[TheSHEEEP]

Just did. No difference.

This does not happen on Brave, btw - but Brave has other issues with Twitch, which made me try using Firefox for Twitch in the first place.

[AdamWr]

That's a strange issue. I still can't reproduce it, and I don't recall any similar problems.
Could you please check if the problem occurs in a new browser profile with only the AdGuard AdBlocker and AdGuard Extra (Beta) extensions installed?
If the problem persists, could you please check if the same thing happens when the userscript (https://github.com/AdguardTeam/AdGuardExtra#userscript) is used instead of the extension?

[TheSHEEEP]

So far, it seems that using the Tampermonkey script solves the issue.

With the script, the experience is a bit more stop&go - when an ad comes, there is a second or three of nothing (as if stream stopped or I clicked pause), then it switches to that ad blocking mode with the banner while showing the stream normally. And then the same again once the ad is over.

Still a lot better than using the extension - that was more smooth (no real pause when an ad starts, or much shorter), but unusable due to the audio issue.

Odd, I've only used the userscript on Firefox and I'm experiencing this issue. Audio is perfectly fine while blocking ads, but gets super desynced, skippy, and choppy after it stops. If I give it enough time though, audio resyncs but still lags behind consistently the video by a second or so.

[2meito]

Nevermind? The issue seems to have disappeared overnight for me haha. I did only try one stream yesterday, so maybe it was a fluke occurrence.

[2meito]

Alright, it seems it gets fucked on specific streams. For me, it was on patstaresat.
