Audacity volume so low

So I was editing an audiobook file last night and just bumped my headphone jack and all of a sudden the playback volume on audacity went really low. It was working fine up until then and now I have to have the volume at 100% to hear the playback. I did update to 3.1 but everything was fine until that bump. I checked all the settings and volume levels on the computer and Audacity but it is still very low. If I play a YouTube video or MP# file outside of Audacity the volume works normally. Seems to be only when I am playing a file back in Audacity that the volume is so low. If anyone has any ideas I would appreciate the help. I have tried the Open Volume Mixer on Windows also and it is set correctly.

Make sure the [u]Audacity Playback Device[/u] didn’t get changed.
