The square plug lines up with the slot only one way. Gently place it in the jack and rotate it while applying light pressure until it lines up and pops in
On my laptop I'm able to put skullcandys into my audio IN jack, i think it will work the same for you
No. A 3.5mm jack is a copper electrical connector while an optical port isn't. Although it is possible to obtain converters between optical and copper, it is an expensive route to take and almost certainly there is a lower cost alternative to the problem.
To use analog 3.5 mm jack RCA cables and the PS4 optical audio cable, you will need a DAC; then your Logitech speakers should work.
A coaxial digital output (usually an RCA jack) can connect to a digital optical input using a coaxial to optical digital converter. This is a small box that goes in between the two products.
An optical jack, often referred to as a TOSLINK or optical audio connector, transmits digital audio signals using light. It employs a fiber optic cable to convert electrical audio signals into light pulses, which then travel through the fiber. At the receiving end, a photodetector converts the light back into electrical signals, ensuring high-quality audio transmission with minimal interference. This method allows for high-fidelity sound over longer distances without degradation.
You have to plug the audio device's connector into the optical connection on the back of the system. The connection is next to the HDMI jack. The audio device must also be digital, not analog.
More common terms for digital optical audio cable; optical audio cable, cable, digital optical, but the shortest and most well-known term is "cable".
An optical cable is a plastic or fiberglass wire that transmits digital audio from one device to the other.
A rear panel optical jack, often referred to as a TOSLINK or SPDIF jack, is an audio connection interface found on devices like televisions, sound systems, and computers. It uses fiber optic cables to transmit digital audio signals in a high-quality format, minimizing interference and signal degradation. This type of connection is commonly used to connect components such as DVD players to surround sound systems or soundbars, providing clear audio output.
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.
The audio signal to the speakers are not cut off since the connection to the front panel and speakers are in parallel.
You can get an optical to coxial converter box if your receiver has a coaxial digital input. If it doesn't, you will have to purchase an optical digital to analog (D to A) converter.
