I couldn't hear the audio clear enough to be sure. Any better audio if the issue without the audio pops from the phone?

Currently no. I'll try to find a way to record clearer audio.

sounds like hard drive starting have a head crash. try running hdtune see if there any smart warnings and use the vendor test tools.
