How do I switch between audio outputs?

Audio output on a computer allows you to hear audio through speakers, headphones, or other devices. There are several different types of audio outputs that computers utilize, including analog ports like headphone jacks, digital ports like HDMI and USB, and wireless protocols like Bluetooth.

The audio output ports built into your computer or external audio devices determine how you can listen to audio from your computer. For example, if your computer only has HDMI and no analog headphone jack, you would need to connect it to a display or receiver with speakers to hear sound.

Understanding the different audio output options available can help you choose the right speakers, headphones, or other equipment to work with your computer setup. It also allows you to switch between them to send audio where you want it.

Speakers

Speakers are the most common and straightforward way to get audio output from your computer. There are many different types of computer speakers available, from basic budget options to high-end audiophile speakers. When selecting speakers for your computer, consider the sound quality, power/volume, number of satellite speakers, and any extra features like a subwoofer or built-in headphone jack.

Connecting speakers to your PC is easy – they plug into the audio output ports found on the back or front of your computer. Most commonly, speakers connect via a 3.5mm audio jack or USB port. Higher-end speakers may use other connections like RCA, optical, or HDMI. Refer to the speaker manual for specifics on how to connect your model. Most speakers will instantly be recognized by your operating system and set as the default audio output device.

For the best audio experience, choose a set of speakers suited for computer use, with shielded drivers that minimize interference. Look for options with at least 15-20 watts of power for sufficient volume levels. Position the speakers properly, a few feet away pointed towards your sitting position, placed at ear level while seated.

Headphones

Headphones can be connected to a computer, phone, or audio device in several ways to switch between audio outputs. The most common connection methods include:[https://www.arkartech.net/blogs/blog/headphones-vs-speakers-what-is-the-difference]

Standard 3.5mm audio jack – Headphones with a 3.5mm plug can be connected directly into the corresponding audio jack on a device. This will typically disable the speakers and route all audio through the headphones.

USB – USB headphones plug directly into a USB port and are detected as a separate audio output device. The audio can be switched between USB headphones and regular system speakers in the sound control panel.

Bluetooth – Wireless Bluetooth headphones sync with phones, computers and other devices, allowing you to listen to audio wirelessly while disabling other outputs. Bluetooth must be enabled on the source device to connect.

Lightning/USB-C – Some modern smartphones like iPhones use a Lightning port rather than a headphone jack. Specific headphones with a Lightning connector are required to plug into that port for audio output.

To switch between headphones and speakers, simply plugging headphones in will typically disable speakers and route audio through the headphones only. Unplugging the headphones will activate the speakers again. You can also manage audio outputs via the control panel on your device.

HDMI

HDMI (High-Definition Multimedia Interface) cables can transfer both audio and video signals. To output audio through HDMI, connect an HDMI cable from your computer’s HDMI port to an external device like speakers, a soundbar, amplifier, or TV that has HDMI input ports. The HDMI cable will carry the digital audio signal to the device.

However, note that HDMI cannot transmit audio alone – it will always carry both audio and video signals together. So if you want to output audio over HDMI without any video, you will still need to have a monitor or other display connected to view the blank video signal. There is no way to strip the video data and transmit only audio via HDMI cables (Source: Microsoft Answers).

To ensure your computer outputs audio over HDMI, go into your audio settings and set the default output device to the HDMI port. You may also need to configure the connected HDMI device to use its HDMI inputs for audio. Refer to your device’s documentation for specific instructions. With everything set correctly on both ends, you will get digital audio transmission to your speakers or receiver through the HDMI cable.

Optical/SPDIF

Optical/SPDIF is a digital audio connection that uses light to transmit audio signals. Optical cables, also known as TOSLINK, use fiber optic technology to send digital audio between devices.

To connect devices using optical/SPDIF:

Make sure both devices have an optical input and output.

Obtain an optical cable, also called a TOSLINK cable. These have square connectors on each end.
Connect one end of the optical cable to the optical output on the source device.
Connect the other end to the optical input on the receiving device, such as speakers or an AV receiver.

The optical output will need to be set as the audio source on the receiving device.
Optical cables transmit pure digital audio signals for high quality sound.

Optical connections allow for longer cable runs up to 30 meters. The cables are less susceptible to interference. According to Electronicshub, the optical digital signal results in zero loss of audio quality during transmission.

Bluetooth

Bluetooth allows you to wirelessly connect audio devices like headphones, speakers, and microphones to your computer. To use a Bluetooth audio device, you first need to pair it to your computer. The pairing process allows the two devices to find and connect to each other.

To pair a Bluetooth device on Windows 10, go to Settings > Devices > Bluetooth & other devices. Make sure Bluetooth is turned on, then select “Add Bluetooth or other device.” Your computer will search for discoverable Bluetooth devices. Select your audio device from the list, and follow the on-screen instructions to complete pairing. You may need to enter a PIN or press a button on the device.

Once paired, you can select the Bluetooth device as your audio output in Sound settings or the volume icon in the system tray. Bluetooth audio quality can vary depending on the Bluetooth version and codec supported. Bluetooth 5.0 supports higher bandwidths up to 2Mbps, while advanced codecs like aptX and LDAC offer improved quality over the default SBC codec. According to Sound Guys, using an aptX HD Bluetooth headset can provide “nearly indistinguishable” quality from a wired connection.

USB

Connecting USB audio devices is a common way to switch between audio outputs on a computer. USB audio interfaces allow you to connect microphones, instruments, speakers, and headphones to your computer via a USB port. Some benefits of using a USB audio interface include:

– Plug and play connectivity. USB devices are easy to set up – just plug them into your computer’s USB port and they are ready to use. No drivers to install.

– Flexibility. USB ports allow you to connect and disconnect audio devices quickly. You can switch between different mics, headphones, and speakers seamlessly.

– Higher quality audio. USB audio interfaces provide better quality audio input and output compared to standard computer soundcards. They have dedicated audio components optimized for recording music and audio [Source].

– Additional inputs and outputs. USB interfaces offer multiple inputs for mics and instruments, and outputs for headphones and speakers. This allows you to connect several devices at once.

– Portability. Since they connect via USB, most interfaces don’t require additional power. This makes them easy to set up anywhere and move between locations.

Some popular USB audio interface options include the Focusrite Scarlett 2i2, PreSonus AudioBox USB, and the Behringer U-Phoria UMC202HD. Overall, USB audio interfaces provide a versatile way to connect and switch between audio outputs for music recording, podcasting, and general computer use [Source].

Audio Jacks

Audio jacks, also known as headphone jacks, allow you to plug in headphones, speakers, or other audio devices to listen to audio from your computer. There are a few common sizes of audio jacks:

2.5mm – Typically used for smaller devices like smartphones and tablets.

3.5mm – The most common audio jack size, used by most headphones, earbuds, computer speakers, etc.
6.35mm – Larger audio jack frequently used to connect instruments, studio monitors, and other high-end audio gear.

Most desktop computers and laptops have both front and rear audio jacks that you can use. The front audio jack is usually more conveniently located if you want to quickly plug in headphones or a headset. However, the rear audio jacks on the back of the computer sometimes provide higher quality sound.

You can switch between the front and rear jacks by changing your sound output device in your computer’s audio settings. For example, in Windows 10, you would go to Start > Control Panel > Hardware and Sound > Sound to change your playback device.
