Check the documented behaviour
Google says media can continue playing when you move to another Chrome tab. If you open a support article and still hear the programme, that can be expected browser behaviour rather than proof that another device or service account is playing unexpectedly. Identify the source before drawing a broader conclusion.
Use the actual transport
If the intention is to stop the programme, return through the browser’s Media control or the correct tab and use the available pause or stop action. Simply hiding the tab, opening a new window or placing another app over it does not establish the playback state. Inspect the player’s own visible result.
Separate browser and service questions
A continuing local browser session does not tell you the provider’s connection allowance or how it counts active viewing. Those are service facts requiring the provider’s current terms and actual account information. Do not infer a universal billing or device-limit rule from the fact that sound remained after switching tabs.
Make the next comparison clear
For a sound problem, note the tab and media item, then change one control at a time. If the sound continues after the identified source is paused, look for another sounding tab or application. Describing the visible navigation and actual transport action separately prevents a simple background tab from being reported as a mysterious duplicate soundtrack.
Questions, answered
Does switching tabs necessarily pause media?
No. Google explicitly describes continued playback.
Does that reveal a provider’s connection allowance?
No. That is a separate service fact.
