Product specifications

To modify the default microphone earpiece audio output settings

open the control panel and then open Sounds and Audio Devices.

The solo-Desktop audio codec software will be selected and

shown similar to the following screen (dependent on Windows

operating system and other audio software previously installed).

Opening the Volume

settings for “Sound

recording” shows the

levels selected for the

microphone input

(Capture) on the

computer. Make sure that

the level for the

Microphone is close to

the top (maximum) and

that the Mute box is not

checked.

Opening the Volume settings for “Sound playback” allows you to

control what you hear in the Microphone’s earpiece. Adjust the

speaker level at the master Volume control if necessary. To

prevent the Microphone directly feeding back its own audio to the

earpiece (i.e. “sidetone”), check the “Mute” box in the “Microphone”

volume control panel. It may be necessary to use the Options-

Properties menu to display the “Microphone” volume control.

IP telephony and computer telephony applications (Skype, for

example) may also offer options for controlling the audio levels and

playback capabilities. Please consult the application guide for the

software package for additional instructions.

To playback audio through the internal or external speakers of the

computer instead of the earpiece, change the Sound playback

Default device to your regular audio codec (SigmaTelAudio in this

example) and click on Apply or OK.

Note: Laptop computers with built-in microphones may continue to

operate even when the solo-Desktop software is running. To

prevent the built-in microphone audio feeding through to the

speakers, check the Mute box on the laptop audio program Input

Monitor, as shown below.
