Enable the tab mute button that's existed in chrome for years but is still hidden:
Go to URL chrome://flags in a new tab
Search for the ‘Enable tab audio muting UI control’ flag
Hit the ‘Enable’ link
Relaunch Chrome when prompted (on Chrome OS a full restart is required)
Now you can click the little speaker that appears next to the tab's close button when a tab is playing sound to stop that tab from playing audio.
God knows why this isn't enabled by default, somethingsomething advertising money...
