System sounds and Music in 2020.
Can I seperate system sounds from Music so that music plays through external speakers and system sounds play through internal speakers? (2019 iMac 27" with Catalina)
(reason: so that an email alert doesn't blast the house down while playing loud music and similarly with watching films, DVD, online streaming, Safari or any software that uses sound.)
