Loss of sound and freezes-bufferization in Youtube videos

[Il-po]

Good evening! Sometimes wblock last version and previous had loss of sound on YouTube videos, mostly on 1.75-2x speed. I remote 5 sec back or forward and sound begins once again. I noticed it on all adblockers(Ubol lite, adguard, wblock). Definitely connected to using adblocker.
One more problem: when watching on 1.75-2x speed 4k YouTube videos due to adblockers(same 3 tried) videos freezes and need to bufferize, sometimes freezes in bufferization, need to reload page or moving far forward/back. Sometimes even on 1440p/1080hd quality videos or in auto mode goes to 480p like...
Any possible fixes?
Thanks

This is an issue with the current version of AdGuard's scriptlets. The next release of wBlock will ship new scriptlets which should resolve this issue.

Thank You for app and reply. But I check and on Ubol also same loss of sound + bufferization problem, adguard I try full payed last version and free last version and both have same problem with sound, less problems with bufferization on payed last version(dns filtering?), and similar to ubol/wblock bufferization problems. Ubol as I saw uses Peter Lowe+Easylist vs adguard list for wblock and adguard payed and free ones.
I wrote to Ubol author about sound and bufferization in autumn 2025 and he said it's a problem in YouTube itself and I need just to wait. I wrote several times to Youtube support but no answer.

I'm on 300mbit/s att fiber in Ohio--> Chicago shows good/great on cloudflare speed test(350/330 down/up). Bufferbloat mostly A grade(! for games), B sometimes(in Autumn 2025 it was more B with ! for games, so att upgrades rerouting/AI reroute a little bit).
I try using DNS from google, cloudflare with sometime better results in Autumn 2025 but now now significant difference vs att dns.
