Hi, I have a 2 month old HP Pavillion dv2130ea and the sound keeps on disappearing. I'll start the latop and all will be fine. I'll see the speaker icon on the toolbar. Then I double click it the sound controls are there. After 10 minutes or so the sound control just disappears. When I double click the speaker icon on the toolbar it will come up with an error box saying "There are no mixer controls available. Click on control panel and add hardware". In device manager I have the following hardware under sound. Audio Codecs Conexant High Definition Audio Legacy Audio Drivers Legacy Video Capture Devices Media Control Devices Video Codecs The OS is Windows XP Media Centre. I have de-installed and re-installed the sound drivers using the "Application & Driver Recovery program" and to no avail. I have also used the driver from the HP site and also followed their instructions to leave everything but Audio Codecs and Legacy Audio Drivers. I have tried callling HP but that was no help. Help! I thought I had bought a good laptop!
