I am well impressed with the technical knowledge and complexity of posters running s2a on rooted phone but so glad I don't have to do all that to keep s2a. I have used s2a, without reinstalling, for last 8 months on non root Samsung note 9 with wireless AA set up.
Works flawlessly, with sound and audio for most streaming apps non drm protected. Installed s2a with AA Ease on android 9 and AA version 6.6xxx. Upgraded phone software to android 10 and current version of AA is 7.7xxxx. I would suggest that a 'compatible' non root phone is less hassle and much easier than using a rooted phone.
