Sound glitches - car revs freeze

Hey!

Unsure if this has been put out there, I see the other post regarding sounds crackling/static being investigated, though I didn’t see this mentioned.

Periodically, when driving, the sounds of the car will “freeze” for anywhere between 1-10 seconds, where you hear the engine sat stick at a constant rev - even when you accelerate or decelerate, before catching up and continuing normally. I can’t work out a trigger, it just seems to happen occasionally. A number of my friends are having the same issue, so it doesn’t seem to be an isolated issue my end.

Is this known, or can this be looking in to please, as it is incredibly irritating!

Thanks!
