Windows 7: No audio will come out of speakers until reboot?

No audio will come out of speakers until reboot?

The audio to my laptop has been going silent on me lately, and I'm not sure if it's being disabled by something, or if there is a bigger problem going on.

I don't exactly know what triggers it, it just seems to go out at random times. The only sure way I know to fix this, is to reboot my system. But I want to know why it decides to go out in the first place?

I only put my system to sleep when I'm done with it, and when I'm ready to use it again I wake it up. The audio will work fine for many more sleeps, until it comes time to reboot due to strange audio loss.

Can someone help me figure this out?

First your PC audio is NOT the NVIDIA HD Audio, its "IDT HD Audio". The NVIDIA is for HDMI audio.

Check to make sure you are using the HP supplied IDT HD Audio Codec driver. Non-Vendor drivers, in many cases, can cause problems.

Are you plugging in an HDMI cable? When you do that the sound automatically changes from the "Speakers" (IDT in your case) to HDMI as the default Sound Playback device.

I'm not using an HDMI cable, but I do have a USB powered Logitech stereo speaker plugged in (it's just an external speaker), that receives audio from a cable running to the 3.5mm jack on the front of my laptop. As far as I know this speaker does not receive audio directly from the USB port in any way.

Whether or not this speaker has a connection to the sudden audio loss I'm experiencing, I'm really not sure. The speaker works fine otherwise.

When the audio goes out, it goes out on all fronts--the laptop speakers, the USB external speaker, and/or any headphones that I may plug in.
