My audio card won't work from this morning.
Problem: This device cannot find enough free resources that it can use. (Code 12)
What can I do?
Generally this means that more than one device is trying to use the same I/O port. Open device manager and see if there are any exclamation points next to any items. You want to locate the device that is causing the I/O conflict and then disable it.
Did you install any hardware or software recently that may have changed your configuration? If so, you can also try uninstalling the hardware/software or even rolling back to a previous version of Windows using the System Restore tool.
