Just adding my voice to the crowd here - brand new 2 week old macbook pro 14 inch with the recent monterey update that came out last week - crackling on youtube and spotify on chrome every 10 mins - I never had any problems with sound on my 'ole faithful 2014. I can't bear safari so I never use it. Hoping this is a software issue that can be rectified in future updates. As the previous poster said - I'm super disappointed - never expected this from a £2k machine.
