When starting win 7 the speaker makes noise until audio driver is used

[jyrgen]

Hello.

I have a computer with external active speakers connected to the 3.5mm phone plug. I'm using win 7 32-bit and when I start my computer the speaker starts to make strange sounds, almost sounds like an old modem. I have disabled the start-up sound since I don't want that, the noise is there until I do anything with the sound driver, or so it seams. If I for example I play a sound or even mute/enable the cd volume the sound stops and don't come back until the next time the computer is started. I have had the computer on for a long time without doing anything and the sound don't stop until I do something with any sound or sound setting.

Additional things I have tried so far to fix the problem but not succeeded:
1. I have been into BIOS and the sound does not start in BIOS, it is when windows is starting the sound starts.
2. Re-installed driver
3. Tried to set the register DrvAzComIdlePowerState and a few more to 00 00 00 00.

What kind of PC do you have? A Laptop or Desktop? If its a Desktop you should be connecting to the GREEN speaker jack.

Do you have the correct sound driver? In most cases the PC Vendor (or motherboard in the case of a home built) sound drivers are the preferred. Non-Vendor drivers, in many cases, either do not work or do not work correctly.

If you have the correct sound driver, go to the Device Manager and RIGHT click on the entry for your sound to highlight it and then LEFT click "Uninstall". DO NOT check the box to also uninstall the drivers. Restart the PC and after Windows starts it will detect and reinstall the sound. This will put the sound initialization in a different place in the sequence and may even put it on a different shared IRQ (Interrupt) and maybe fix it.

I have a desktop with this motherboard: Jetway - Tech.On The Move - IPC Board - NC9B-HM67.

Correct, I'm connecting it to the green headphone jack

I have the driver they providing on the motherboard homepage

I tried your suggestion with uninstalling but unfortunately no difference.
