### Process All Input and Output Streams
By default, EasyEffects processes all input and output streams.
This includes [loopback devices](/wiki/linux/pipewire.md#virtual-devices) with which it may lead to
some problems - for example
[problems with virtual devices](/wiki/linux/pipewire.md#problems-with-input-an-output-of-loopback-devices).
It can be disabled and re-enabled in the `Preferences` under `Audio` by deselecting or selecting the
switches for `Process all output streams` and `Process all input streams`.

This section focusses on the temporary and permanent creation and removal of virtual devices like
virtual sinks and sources aswell as coupled nodes like loopbacks.
Please note that problems may occur if [EasyEffects](/wiki/linux/easyeffects.md) is used in
combination with virtual devices.
This mostly is based upon standard configuration.
Most importantly stream devices may have problems as explained in the

### Problems with Input an Output of Loopback Devices
If the input and output of devices of the types `Stream/Output/Audio` and `Stream/Input/Audio`
automatically switches back to [EasyEffects](/wiki/linux/easyeffects.md) then EasyEffects is not
configured correctly to use with such devices.
This also can lead to problems with using [loopback](#loopback-input) and other
[virtual devices](#virtual-devices).
It can easily be fixed by not processing inputs and outputs automatically.
This is described in depth
[the corresponding section of the EasyEffects entry](/wiki/linux/easyeffects.md#process-all-input-and-output-streams).
### Fix Crackling
Crackling can occur in various situations.
