ALSA switching hotkey and LED icons

Hi
I’m using Linux Mint 22.3 and Ardour 9.7. I go into the Audio/MIDI menu all the time since ALSA hogs my sound when I go to Youtube and other music sites.
Could someone add a hotkey to the Stop/Start function? And maybe a LED style icon up in the information field, to make it obvious whether ALSA is running without checking the menu?
