The term "Classics never die" is not a common word when it comes to PC wiring. Here any communication system is becoming increasingly modern as well everything is normal digital because it provides better quality and speed, but when it comes to audio connection something changes. And the fact that the cables are as old as the 3.5 mm minijacks has become a thing of the day and will continue to be a long time.
However, the fact that it is the most widely used does not mean it is the best.
PC audio connection
We'll see three opportunities we have when connecting audio systems to PC, including the analog mini-jack used previously and digital audio, via HDMI or S / PDIF (Toslink).
3.5mm minijack analog connectors
Almost the most common audio cable format used on PC today is the analog minioker, since it uses it from standard speakers to any headphone system. However, the audio signal in the analog cable is electrically transmitted
For this reason, analog audio cables they are subject to interference Radio and Electrical Radio -, why in normal conditions and if you choose, it will always be best to connect the PC through digital connector such as S / PDIF or HDMI.
Digital audio via S / PDIF – Toslink
A good way to describe a digital sound that uses the S / PDIF signal and the Toslink connector is to say it is visible, because the signal was sent digitally by a fiber optic cable using light on the fiberglass tube to transmit the signal, instead of on the copper cables. Technically, comparing these cables with analogs we've seen before is like comparing HDMI and VGA video signal.
The main advantage of using these type of cables is that the 5.1 surround sound signal can be coupled to a single cable, and in fact compatible with structures such as Dolby True Surround, DTS, etc. If, for example, you have Dolby-compatible speakers but your sound card isn't there, the optical cable may provide opportunities for the sound card even if it doesn't support it. This means that, in this case, if you had a dedicated audio card compatible, you would not need a special cable.
HDMI audio
We finally reach HDMI cables, as you know more than video capable of transmitting audio and data, because it's digital after all. It works with all types of Dolby loses, such as the Dolby TrueHD and DTS HD Master Audio used on the Blu-Ray module. It is also compatible with Dolby Digital Plus, Dolby Atmos (recently featured on Netflix) and has the highest bandwidth of all audio streams. This allows, unlike the optical cable we saw earlier, support for 7.1 systems including.
HDMI transmits digital audio and in good condition you can do it even without any pressure due to its high volume, which supports samples up to 192 KHz. Where digital cables can carry two PCM audio channels without compression, the HDMI 1.4 cable can carry up to eight channels and HDMI 2.0 raises the figure to 32. Almost nothing.
Another thing to keep in mind is HDMI ArC, which is nothing more than audio recovery channels and which allow you to use HDMI compatible TV reception for the TV, allowing for remote control of the TV remote control.
What better to connect to PC audio?
Once the features of the three possibilities have been explained, it is clear that although the most commonly used communication type is the 3,5mm analog minijack, it is actually a very good option with HDMI. And, even if it surprises you, you can use the HDMI graphics card port with it, now that you know you have no excuse.
Of course, it has to be said that with a standard PC without high-quality audio systems, analog communication is still good enough. But to choose, you know that the best is audio in HDMI, followed by an optical connector, and finally, an analog.
