If you're experiencing issues with videos or audios not playing in the background while you switch tabs or use other apps, it could be due to the settings of the specific website or application you're using. Here are a few suggestions to help troubleshoot the problem:
Check website or app settings: Some websites or applications have settings that prevent videos or audios from playing in the background or when the tab/app is not active. Check the settings of the specific platform you're using, such as LinkedIn or WhatsApp, to see if there are any options related to background playback.
Try a different browser or app: If the issue persists, try using a different browser or app to see if the problem is specific to the one you're currently using. Different browsers or apps may have different capabilities when it comes to background playback.
Use browser extensions or third-party apps: There are browser extensions or third-party apps available that can enable background playback for videos or audios. For example, for YouTube, you can try using extensions like "Enhancer for YouTube" or "YouTube Playback AutoHD" which provide additional playback options.
Keep in mind that not all websites or applications support background playback, as it can be dependent on their design and functionality. Additionally, certain platforms may have restrictions in place for copyright or other reasons.
Overall, it's recommended to explore the settings and options within the specific websites or applications you're using, and consider trying alternative solutions such as different browsers, extensions, or apps that may provide the desired background playback functionality.
