I have a HP Pavilion m7750n that originally was installed with Windows Vista. It's had it's hard drive replaced many times over the years, and now it's running on Windows 8.1 64 bit.
The problem is: the audio driver went missing somehow
I can't find it on Device Manager (no "Unknown Devices" show up on the menu)
The only "Sound, video, and game comtrollers" drivers that show up are:
1. Hauppauge WinTV HVR-1600
2. NVIDIA High Definition Audio
3. NVIDIA Virtual Audio Device
All of this happened after I used the "Refresh" option Windows 8 has. The right sound driver showed up on Device Manager and worked before I did this.
On sound options it says the only audio devices I have are some HDMI outputs. The only way to get sound out of my PC anymore is to hook it up to my TV from a HDMI cable connected to the HDMI port on my video card.
Does anyone know how I can find the audio driver so i can use my desktop speakers again?
