I built my own pc recently, and everything was workign fine, except for the sound. I tried uninstalling and reinstalling the drivers about 5 times, to no avail. I bought a monitor with a headphone jack, however, which hooked up to my graphics card with an hdmi connection, and the audio jack on the monitor gave me sound. I want a microphone jack for reasons, however, so I bought a sound card. Unfortunately the sound card does not output any sound either. It is not a driver problem and it is set as the default device. Please just give me some insight.
