Hello, I have been having a problem with my laptop for the past month or 2, and that is my laptop speakers are not working. I can only receive sound through the use of headphones or speakers plugged into the jacks. I have tried reinstalling drivers, but they never solved the problem. When I look through 'Device Manager' the only problem I could find is that there is a yellow triangle next to my 'Base System Device', which is under 'Other Devices'. However, I do not know how to fix that problem as well - assuming my stereo problem and the 'Base System Device' is connected. My laptop is an HP Dv2615us. Thanks. PS: Sorry if this is in the wrong section.
