My volume icon is greyed out and I cannot get volume

I didn't have a light, but I inserted my headphone plug. The icon turned dark, and when I removed the headphone plug, I was able to adjust the volume again. So, it must have gotten stuck when I removed the plug earlier. Thanks.

Thank you so much!! this saved my life 😀

You are brilliant. This worked for me. Thanks so much.
