I am using an HP Envy dv-7-7259nr laptop with Win 8.0 x64 (HP site: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=5327928&lc=en&cc=us&dlc=en&lang=en&cc=us)
I don't understand why this is happening but upon starting up my system my sound in the speakers are not working in any application that utilizes sound. To remedy this I go into Device Manager and navigate to the Sound, video, and game controller and then select the IDT High Definition Audio CODEC component by right-clicking. I then disable and re-enable and sound is fine afterwards. This is annoying. I tried installing the driver again and from what I can tell it installed properly. The driver version is 6.10.6425.0 (dated 8/19/2012) and provided by IDT. Showing reinstalled 7/10/14 with Service Added (STHDA) and the device installed is stwrt64.inf
I am not sure what to do with this one.
I also have listed in the Sound, video, and game controller two other audio devices:
1) Intel® Display Audio
2) NVIDIA Virtual Audio Device (Wave Extensible) (WDM)
Any help is greatly appreciated.
