I have a new motherboard, MSI H81M-E33. The new case (cooler master elite 110) came with one of those tiny 4-pin speakers, as shown in my picture.
Everything seems to work fine, a fresh Win 7 installation boots without issue, but I get no POST beeps from the MOBO, and there is no sound in after booting-- Windows says that no playback device is available.
Headphones work fine, so it is not all sound, just the little internal speaker that isn't working. MOBO & Chipset drivers all installed & updated, and Device manager shows no problems with any devices.
The image shows the Mobo pins diagrams and the mini speaker. JFP2 is where I have the speaker connected.
So, am I doing something wrong, or is it more likely that its just a bad speaker?
