[HP ProBook 4540s, Intel PantherPoint HDMI, Digital Out, HDMI] Background noise or low volume

[Khan Rafin Ahmed]

Sound Quality is poor. When I am powering up the volume to 100% audio sounds distorted. I am using Windows 8.1 in this very laptop as well where the audio is working perfectly. So, it's not a hardware related problem. Audio level is low too. Thanks.
