Participants can't hear my background speaker

Hi there,

Please help!

I am on the latest version of zoom.

I am on Windows 11.

I have been teaching online fitness classes since the start of covid.

I share Spotify music via zoom which works perfectly.

I wear a bluetooth mic which works perfectly.

I use the app Seconds as my timer and it plays via my Bose speaker beside me.

I updated my laptop a few months back (windows 10), and since that day, my attendees can hear me perfectly, can hear my music perfectly but they can't hear my timer via my speaker that is located in the room beside me while I teach.

I tried turning on my old laptop to compare settings, but it won't work, hence new laptop!

Nobody told me they couldn't hear the countdown timer until very recently when a few of my regulars asked me why I have stopped using a timer. I told them I hadn't, I can hear it perfectly, obviously because it is right beside me! They said it's really annoying that they can't hear the countdown of the exercises.

Can anyone help please?  I am teaching a class tomorrow at 7:15am, yikes!

Thanks,

Colette

I assume it is a setting on my new laptop that is different to my old laptop, OR is it a change that Zoom has made, I am unsure!
