I've been using my Dells this way for over two years now. Does your Dell have a coaxial or optical digital output? What are you using as playback software? Hopefully something other than Itunes.
Unless you have a video / sound card that passes both audio and video through HDMI. You'll still need a optical or digital coax output for sound.
If focused on two channel, a Dac fed by the PC into a analog preamp then amplifier would be a better option.
Or you could go with an all in one DAC, preamp, amplifier unit that has a digital pass through, so you could feed a separate AVR the rest of the channels.Your two channel music would only come from the all in one. You'd use the AVR when you wanted 5.1 sound or higher.
