Hello Maltesem,
Thank you for posting on the HP Forums!
I understand that the sound on your computer is not working properly. I will do what I can to assist you! For better assistance, I do require the computer's operating system. If you require assistance locating this information, please reference this website to determine your Windows operating system.
In the meantime, please try the suggestions in this HP document to restore your sound settings: HP Notebook PCs - Resolving No Sound or Audio Problems
Thanks again for posting on the HP Forums. Have a great day!
