Squeaky speaker like interference noise in MacBook Pro 2015
Hi there :)
I’ve purchased this laptop from company who repair laptops.
Left speaker is “squeaky” like it would have interference (and only when is active)
I’ve replaced it with second hand from eBay and still got such a noise - is it possible that something else is broken? Connector looks ok.
Can it be something connected with headphone jack or something else.
Definitely obvious things like new macOS reinstall - SMC and NVRAM reset did not helped :(
- No liquid damage - all 10 or more stickers are white
- Both speakers are 100% fine as I swap them and left working one was crackling in right connector.
- System plays music great on headphones - so my guess audio chip is fine.
- Squeaky speaker still plays music - but with squeaky background.
