Soundcard interfaces are used primarily to isolate the PC from the transceiver. This reduces the risk of a ground loop, preventing hum and noise on the modulation. Besides the pure isolation of AF signals some of these devices offer more functions like level adjustment, PTT control, CW keying and a CAT interface as well.
The more recent developments use the USB interface from the PC instead of the serial port for control functions.
