Speaker issue

[Alana2]

I have a Windows 10 computer. Galaxy Book Flex 2.  I do Zoom two times a week. All of a sudden I cannot test speakers on Zoom. No sound. Microphone works fine on Zoom even when testing. Speakers work great when not using Zoom app. I tried my husbands computer (Same computer) except he upgraded to Windows 11. I tried his Zoom. Speakers not working when testing on Zoom. His speakers work great otherwise as well as his microphone just like mine. Is this a Zoom problem due to Microsoft? This problem just started after the outage. I am at a loss right now. I am going to take my computer to a repair shop to find out what is causing this issue, Can I just purchase some speakers  as a work around and plug them into my computer for Zoom. Will that work if I am using my big screen TV that is plugged into my computer as well? I really need the TV screen. The Zoom speakers are the problem. Thank you for any answers you may have regarding this issue.
