A. AudioMotherboards typically have these analog audio panel ports:
Most motherboards have a headphone header to attach to a case front headphone jack. However, since the cable runs through the computer case it tends to pick up electrical interference/noise. You can instead plug the headphones into the back panel line out/speakers, although high impedance headphones may need a seperate headphone amplifier.
The Asus ROG Strix 270e also has digital optical out and digital coax out.
My audio setup:
The back panel of the Modi DAC has optical digital in, coax digital in, micro USB in, USB (micro) power in, and RCA out. On the front it has a selector switch: USB, digital optical, coaxial digital.
The Magni headphone amp has RCA in and RCA out plugs on the back panel (as well as the power in from the wall wart). On the front panel it has a headphone jack and a volume knob.
The computer sound from the Realtek chip is outputted by digital optical to the Modi DAC which converts the computer digital data to analog sound. The Modi feeds the Magni headphone amp by RCA cables. The Sennheiser headphones plug into the Magni headphone amp by ¼ inch cable.
The Magni also has back panel RCA out jacks that are connected to the Yamaha receiver "audio 1" input. That allows the computer sound to be played over the Yamaha/speakers. Plugging the headphones into the Magni front panel jack automatically disconnects the rear panel RCA output.
The aux computer uses integrated Intel graphics. Its motherboard (Asus Prime H270M Plus MicroATX) outputs HDMI and DVI-D. The Dell 2410 monitor with it inputs HDMI, Display Port, DVI-D, and VGA. I use HDMI.
The EVA GTX 1080 FTW outputs HDMI 2.0b, 3 x DisplayPort 1.4, 1 x Dual-Link DVI-D.
The Dell monitors I use are:

Line in/out is the strength for other audio devices like tape players, DVD players, TV's, and audio mixers. Microphones and instrument pickups carry a weaker signal; headphone out and speaker signals are stronger. Since their signal is weaker, microphones typically need a preamp. Condenser microphones require power, usually from the mixer back to the microphone. Dynamic microphones use an electromagnetic coil.
