My sound comes and goes on my HP e9280t. Sometimes I get the realtek hd manager icon telling me that the speakers have been plugged in, and then 1 second later it tells me they have been unplugged. It can keep doing that for minutes until I finally close the message. If I go into the audio manager, sometimes it recognizes speakers and sometimes it doesn't. The 'sound troubleshooter' can't find a solution. I've also tried uninstalling the driver
and re-installing the new one directly from Realtek's site. And I've tried downloading the driver directly from HP's site. Nothing has worked so far. Even when I try to set my speakers to default (when it let's me) I don't get sound. When I do get sound, it doesn't last long. After 30 minutes or so, the speakers will start to sound like static. Any ideas on what could be going on? I also tried going into the BIOS settings and changing the onboard audio from automatic to enabled.
