Hi clee08.
This question should be asked in the
Microsoft Community for Windows, which is more appropriate for this kind of topics.
Did you install the audio driver(s) for your computer? If this is a recent problem, you could try applying a restore point to revert back your system to a previous well functioning state; otherwise, you should try downloading the drivers from the
HP Support site and install them.
Bye.
