Hello, I'm hoping someone can help me out with this. I have a HP 2000 Notebook PC. Product Number: D1E12UA#ABA. Windows 8.1 for 64bit. My laptop's sound has recently stopped working. I have tried everything, Troubleshooting says it can't identify a problem in playback audio or in speakers. I tried updating the audio driver. I tried the test sound in devices, and it says "Device in use by another application." Any advice would be helpful. Thank You.
