S / PDIF stands for Sony/Philips Digital Interface. In the photo above, the S / PDIF port is on the right side. S / PDIF is an optical audio cable format that allows the transfer of digital audio signals from device to device without needing to convert to an analog signal first.
They are both digital connections. Optical usually refers to the ADAT protocol over a fiber optic cable (TOSLINK), while SPDIF is usually transmitted over a coaxial “RCA” cable. “Usually”, optical can carry 8 channels at 44.1/48KHz (or 4 at 88.2/96KHz in certain situations) while SPDIF is stereo (two channels).
Right-click on the S/PDIF icon (it may appear as “Realtek Digital Output,” ” S/PDIF Output” or ” S/PDIF ,” depending on your sound card or motherboard) and select ” Disable ” from the contextual menu.
What is the difference between a digital optical and digital coaxial connection for audio ? A Digital Optical connection uses a fiber optic cable. The digital audio bit stream is transmitted using pulses of light through this optical cable. A Digital Coaxial connection uses a cable that has RCA-type connectors.
The optical jack is designed to output sound when the video you’re watching contains digital audio (PCM or Dolby Digital ® technology). This feature is available on certain digital broadcasts and streaming video, and isn’t supported on standard cable or analog stations.
Distinguished Member. S/PDIF can use different physical connections – in home audio it is either coaxial or optical (XLR in studio use). You should have optical at both ends so a basic optical cable is fine.
Both can pass multi- channel audio, like Dolby Digital. Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio. These formats can’t get transmitted across optical.
Yup. Digital signals are either on or off. Both HDMI and Optical cables are all going to give the same quality signal. The main difference is hybrid TOSlink connections, where one end is a 3.5mm headphone plug, and the other end a conventional optical connector, which Apple use for most of their computers.
SPDIF is a standard for transmitting high-quality digital audio without going through an analogue conversion process. It is used for connecting Hi-FI Equipment, DVD players, CD players, Mini-Disc Players, Sound cards etc. This interface uses RCA phono connectors and 75 Ohm coaxial cable.
Click Settings, DVD, Audio , and then Speaker Configuration. Set sound output to match your speaker system. For example, select 5.1. If you have digital audio , select S/PDIF .
1. Set the Speakers as Default Device 1) Right-click on the speaker icon on your taskbar, and then select Playback devices. 2) In the Sound window, select the Playback tab, right click on Speakers , and then select Set as Default Device. 3) Hit OK. 2) Run Driver Easy and hit the Scan Now button.
Try setting the ” speakers ” as the default audio device by right clicking the sound icon on the system tray -> playback devices -> click on speakers -> set default audio device.

And, in our experience, compared to optical , a coaxial connection does tend to sound better . That’s because it has greater bandwidth available, meaning it can support higher quality audio up to 24-bit/192kHz. Optical is usually restricted to 96kHz.
Higher quality aux cables can also help as they’re better shielded. Optical isn’t foolproof either. In terms of value for money, aux cables are usually cheaper, more versatile, and most commonly found on modern devices than their digital counterpart.
