Where to buy

External USB audio adapter AXAGON ADA-12 easily and quickly adds missing headphones output or microphone input to your computer. It will also serve well as a replacement for the broken original integrated sound card in the notebook.

The sound card is suitable for desktop computers and notebooks and allows you to connect headphones or active speakers and a microphone. Adapter metal housing is made of aluminum and thus provides perfect mechanical protection. Fixed cable guarantees sufficient flexibility. 

The sound card together with the headset will form an ideal accessory for online communication programs such as Skype, Zoom, MS Teams etc. The card is easy to install, just plug the sound card into the computer's USB port and the rest will be done automatically.

A): The basic drivers are already part of the operating system.

B): When you connect the USB sound card to your computer, the necessary drivers are automatically detected and installed.

A): If the USB sound card is not displayed in "Device Manager", there may be a USB port malfunction.

B): Try plugging the sound card into another USB port. The sound card should be detected and the drivers loaded automatically. If the problem persists, plug the sound card into the USB port of another computer to verify its functionality.

A): You probably have enabled the “Listen to this device" option in the sound properties of the microphone.

B): To disable this option, go to

A): The USB sound card cannot be used without a computer, e.g. by plugging into a TV.

B): The USB sound card uses the computer, its operating system and drivers for its operation. So it cannot operate without a PC.

A): The sound interference is probably caused by a wireless mouse transmitter.

B): We recommend that you place the mouse transmitter as far as possible from the sound card (preferably on the opposite side of the computer - the transmitter to the USB on the front PC panel and the sound card to the USB on the back of the PC - use a USB extension cable if necessary). If it is a laptop, then one device on each side.

A): The problem could be a lack of resources, check (when a problem occurs) the processor load and operating memory filling in "Task Manager".

B): If the CPU usage is 100% or memory is full, you need to find out what causes this situation. Another option is to connect a sound card to another computer to verify that the sound card is not damaged.

A): On most Axagon USB sound cards, the line input is merged into the microphone input.

B): The sound card has the ability to recognize whether a microphone or stronger "link" signal is connected. So, for example, when recording from the headphones output of a mobile phone, you need to reduce the volume on the phone to 80-90 % or reduce the signal intensity in the recording software so that the signal is not overexcited. In the recording software (such as Audacity), you need to set up the Microphone-USB as the signal source.

A): The USB sound cards generally have a higher latency (delay).

B): The solution is to use the ASIO4ALL drivers ( ASIO are special sound drivers designed to achieve the smallest latency.

A): Yes, for example, the ADA-17 sound card can be used for Raspberry Pi.

B): The installation can be handled even by a layman, only plug the sound card into the USB port of the computer and the rest is done automatically.

A): You probably have allowed to listen to the microphone in Microphone Properties.

B): To disable this feature, follow these steps: Start -> Control Panels -> Hardware and Sound -> Sound -> Recording -> Microphone (USB Sound Device) -> Properties -> Listen -> Listen to this device - uncheck this box and confirm with "Apply".

A): Yes, you can set up two different tracks playing back simultaneously on one computer.

B): This is primarily a software issue requiring a player that supports sound redirection to a different sound card output than is set as "default" in the OS. Such functionality is supported, for example, by the VLC media player.
