Unbelievably this has changed again and now its even more difficult!
Ignore this and see below
They’ve done it again for the 1903 update - shifted stuff around to cause more head scratching! More things are now incorporated into the new setup system and if you want to directly access the old “sounds” control panel to check your input and output devices you can do this:-Right click the speaker icon in the task bar ( that’s the plain one not the Realtek or other sound card one).
Hover over > speaker set-up > to open a secondary menu
Click > advance set-up > to bring up the familiar “sounds” control panel.
Right click the speaker icon in the task bar ( that’s the plain one not the Realtek or other sound card one).
Choose open sound settings.
Scroll down to related settings.
Choose open sound control panel
Or if you like typing then use run and type
mmsys.cpl
As for functionality I haven’t used it enough to draw any conclusions yet.
