I am using a HP Envy purchased in July 2013. In January 2014, I ran into trouble upgrading to windows 8.1, which was solved after a lot of effort by Microsoft. I am running Windows 8.1 now. For the past few week, the audio on my laptop has been acting up. It gets choppy and does not play well. It initially starts out fine but then there are a lot of high squeaking noises or harsh sounds, and after abouta minute the audio stops playing completely. The model number for my laptop is C8P47AV. Please let me know what I can do to correct this.
