I have a DELL XPS Laptop. It has 3 audio ports:
- 1 microphone output
- 1 Headphones Output
- 1 S/P DIF output.
*I'm not using Microphone, so that port is not being used by anything / no wires to
*I've connected the headphones jack to a normal speakers (powered by USB). These speakers have only 2 wires: One for connecting to a headphone jack, and another is a USB plug for power input. They're normal PC speakers, I don't know how to define then in a more specific manner.
To the S/P DIF, I've connected my external speakers using an Amplifier. These speakers are in another room, and the amplifier is placed in my room. 1 Wire connects the speaker and the amplifier, and another wire connects the Amplifier and the Laptop (S/P DIF output)
Question: What is S/P DIF? And how can I control the output on windows?
Currently I'm using the Amplifier Controls to lower down the volume or mute the external speakers of the other room. I tried search for a way to do this via the laptop (windows 7) but couldn't find anything that lets me control the audio output of the S/P DIF. I couldn't also find what the S/P DIF means...
My System Configuration is as follows:
DELL XPS L502X
Windows 7 Home Premium (64-bit) Service Pack 1
Audio Drivers: Realtek High Definition Audio
I'm looking for any application or a feature in Windows or DELL that could control output of the S/P DIF port.
Here's an image of what the ports look like on the DELL Laptop. (This is not my laptop, but some other laptop, image from google)
