Laptop speaker not working

[lucy1030]

I have the HP pavilion laptop 15-cw1511, when I turned on my laptop the other day and played audio from it I could barely hear anything, it sounded very quiet compared to usual and only when I turn my volume up to 60 can I hear what I would normally at the volume of 30. When I plug in my headphones everything works fine but as soon as I take them out the quiet audio starts, however, it does play at a normal volume rarely for around 5 seconds and then disappears. I have a feeling this may be due to the recent update.
