You will need a digital audio switchbox or a surround sound receiver with 2 digital inputs.
An optical audio cable is used to transmit digital audio (AC-3) signal from the source to the receiver, such as from a DVD player to a digital audio amplifier/receiver. You can transmit 5.1 dolby digital or DTS surround sound with an optical audio cable, same as digital coaxial audio cable.
To use a sound card as an analog-to-digital converter (ADC), connect an analog audio source, such as a microphone or instrument, to the sound card's input jacks. Then, use audio recording software to capture the sound; the software will process the analog signal, converting it into a digital format. Ensure the sound card's settings are configured correctly for sample rate and bit depth to achieve the desired audio quality. Finally, save the recorded audio in your preferred digital format.

analog audioRefers to recording audio in a format of continuous vibrations that are analogous to the original sound waves. Before audio recording became digital, sounds were "carved" into vinyl records or written to tape as magnetic waveforms. Contrast with digital audio
A 2-channel digital audio signal, or a encoded DTS or Dolby Digital surround sound audio stream.
Digital optical audio cable can carry data to decoder-enabled devices in a few formats; Dolby DTS is one of many such formats. Some of these can carry surround sound. Besides, optical is digital, and standard sound card output is analog.
Digital format in audio refers to the encoding of sound into a binary system that computers and digital devices can process. This involves converting analog sound waves into numerical values, which represent the audio signal's amplitude at discrete intervals. Common digital audio formats include MP3, WAV, and AAC, each varying in compression, quality, and use cases. Digital formats enable easier storage, transmission, and manipulation of audio content compared to analog formats.
The type of connector on a sound card typically includes 3.5mm audio jacks for line-in, line-out, and microphone inputs. Many sound cards also feature digital audio connections such as S/PDIF (Sony/Philips Digital Interface) ports, which can be in coaxial or optical formats. Additionally, modern sound cards may include USB or HDMI connectors for digital audio output.
Connect the digital audio output from the TV to the digital input of the surround sound receiver.
A digital-to-analog converter (DAC) can be a peripheral or a chip that creates sound from digital instructions. It converts digital audio signals into analog signals that can be amplified and played through speakers or headphones. DACs are commonly found in devices like computers, smartphones, and audio equipment, enabling high-quality sound reproduction.
