Well like the title says, I have recently upgraded to Windows 7 from Windows Vista. Everything was working just fine till last week my audio goes bye-bye. In my taskbar my audio icon it has a white X in a red circle. Plus it says "No audio Ouput Device is installed."
More info, it goes on and off randomly when I shutdown or put the computer to sleep. I have a HP Pavilion dv6700nr,
Processor: AMD Athlon 64 X@ Dual-Core
System type: 32 Bit
Graphics: Nvidia Geforce 7150M/nForce 630M
Any input or help is greatly appreciated.
