in november, i built my daughter a desktop for her Christmas present. until today, everything had worked as expected. today, she for the first time plugged earbuds (known good units) into the front port. but they are completely silent. i looked around thru various settings, but i can not find anything that is related to the front panel. she has speakers plugged into the rear audio port, which work fine. we don't have to unplug the rear audio in order for the front plug to work do we? this has an MSI H110M pro-vd plus mobo.
