The Volume tab
The Volume tab allows you to digitally scale the input and output volume in the audio driver. For the
output channels, the Volume control acts like an attenuator, reducing the output signal. For the input
channels, the Volume control only affects the digital scaling of the signal and does not attenuate the
analogue input signal.
Scaling can be done in steps of 1 dB from 0 to –127 dB.
The Controls
