Win 7 RC detects mic jack as speaker jack.

I used to be able to reset the jack using the Sigmatel Control Panel in Windows Vista, but it seems to have disappeared after the upgrade.

I don't use my front jack for my mike because it's damaged.

Any help would be appreciated.

You need to install new drivers for Win7...
What brand is your card?

Built in Intel High Definition Audio.

Try to find Win7 drivers (probably beta), if there is non, try with Vista driver.
That should work.

Well, not Windows has decided to hijack it and now calls it High Definition Audio.

I found some drivers from the Microsoft Update Catalog, but Windows refuses to install the drivers.

try with Vista drivers, that worked for me before official Win 7 drivers came up.

Nope, Windows just gives me an error code 21 and tells me it can't load the driver.

F..k!!! I ran out of ideas.
