My laptop was fine with this but the laptop comes with the OS and the drivers all figured out. You need to talk to this PC's maker about drivers.
I have my TV hooked via HDMI to my PC which works fine. When I go to switch the audio under the playback tab to PC speakers, which is hooked up, it will not play unless I log off and back on. The work around I have is switching the default device, logging off and logging back on and either device will work fine, it's just kind of a pain. It used to work and one day just stopped.
Any help would be appreciated, thank you!
