I had gotten this as a backup for an older desktop I had occasional issues with. When I had to use it I could not get any audio response. The video functions worked fine, no internet issues, but no audio. After about 3 hours of searching for a way to get audio and trying every possible thing I could find, I gave up and took the hard drive out of the old machine and put it in another case where the C drive had failed after a month, that one now is working fine and I get audio on that one. This one also was supposed to have an optical drive, but it didn't work, the seller sent an outboard drive.
