"Use Voice with Wired Headset" Notification Stops Music
No. The Internet is full random speculation about this issue, ranging from dirty/damaged headhone jack, to hardware issues and defective headphones. All of these lame excuses are wrong. Google Assistant has been intentionally written (several updates ago) to use this method of nagging harrassment to force Android users to enable "Ok Google"/Assistant. Just like your Google Feed cannot be shut off now without completely disabling the Google app entirely, and disabling Play, Gmail, etc along with it. It is just another form of "user herding" so they can further Snoop and send you focused advertising. Not happy with only gathering search terms, they want everyone on board with Voice, befotre they change the user agreement and eavesdrop on end users constantly. This is already happening to wide cross section of users, without any real consent or knowledge. Some of it Google has pushed off on third party affiliates to insulate themselves from inevitable push back and outrage. People are figuring this out, by conversations overheard by phones are changing their advertisment and news feeds.
