Audio issues

I used my AirPods once in a Zoom meeting and the other audio and microphone settings are unavailable.

I was able to use my computer speaker and microphone before connecting my AirPods.

But now zoom client can't recognize my computer device even when i stop bluetooth with airpods.

When I do the audio and microphone test, the output level goes up with my computer speaker but I can't hear any sound or the sound is output for 1 second and then cuts off. The microphone doesn't pick up any sound at all.
