Microsoft Edge desktop · Research guidance. Instructions are based on publisher guidance; a UK IPTV account was not tested on this platform.
Observe when the problem begins
Keep a note of whether the issue occurs while the page is active or only after another tab has been used for a while. Microsoft’s sleeping-tabs feature concerns background activity and resource use. An interruption during continuous active viewing needs its own explanation rather than an automatic assumption that the tab slept.
Inspect the performance settings
Microsoft places sleeping-tab controls in Edge’s system and performance settings. Use the current Performance section to review whether sleeping is enabled and the selected inactivity interval. A faded background tab can be an indication of released resources. Do not use a remembered older default interval as proof of the setting on this computer.
Review the built-in exceptions
Microsoft lists activities such as active audio, screen capture and visible pages among conditions that prevent sleeping, and offers an always-active site list. A streaming page is therefore not automatically expected to sleep merely because it exists in a background tab. Inspect the actual activity and site choice rather than making a universal claim.
Try the relevant site scope
If keeping a trusted page active is appropriate for the task, add or review that site in the documented always-active list. Note the previous state and repeat the same background-and-return sequence. Avoid entering private token-bearing media URLs into a support screenshot. The public site scope is the useful diagnostic detail.
Keep sleep, discard and device sleep separate
Microsoft distinguishes a sleeping tab from a discarded page; the computer’s own sleep state is another layer again. Record whether the tab resumes or reloads and whether the whole device slept. That sequence helps support identify the right area without reinstalling a working player or claiming that one browser exception guarantees uninterrupted service.
Questions, answered
Is an actively playing audible tab always expected to sleep?
Microsoft documents activities that can prevent sleeping; inspect the actual case.
Is browser tab sleep identical to the whole computer sleeping?
No. Record which layer changed before deciding what setting to examine.
