Just installed a new graphics card. All went well with that; but, oddly, there is now no sound. Speakers are plugged in correctly (on; volume is up & not muted). Device Manager reports all is well. (Just to be sure I reinstalled all [four] audio drivers. Windows troubleshooter finds nothing. The only thing I can think of is that I somehow damaged the cable/plug during the upset, but this is unlikely. So, before I go out and waste money on new speakers I thought to ask if anyone can think of anything I might have overlooked.
