Phone stuck in headphones mode

Hey Tribe,

I was listening to Pandora using headphones, and everything was working well. When I unplugged my headphones, however, my phone didn't switch back to the standard volume control; instead, it stayed in the headphone volume control. Now the ear speaker doesn't work, but the speaker phone still works. So my phone still rings when I get calls/texts/alerts, but I cant hear anything when I answer unless I use the speaker phone or I plug the headphones back in.

I have tried restarting my phone, and a soft reset. Before I do a hard reset, I was wondering if anyone else has experienced this and if there was anything else I could do to fix this.

I am running WP 8.1 Developer Preview on my Nokia Lumia 928.

Thanks!
