# aupanel(1nas)

allows user adjustment of Network Audio System device attributes

## NAME

aupanel - allows user adjustment of Network Audio System device attributes

## SYNOPSIS

**aupanel** \[**-audio** *servername*\] \[**-device** *id*\] \[**-interval** *seconds*\]

## DESCRIPTION

*aupanel* provides an X-based window-oriented interface allowing the user to adjust the attributes of the devices provided by the Network Audio System service.

## OPTIONS

The following options may be used with *aupanel*:

- **-audio** *servername*

  This option specifies the Network Audio System server to contact.

- **-device** *id*

  This option specifies the initially activated audio device on the server. If the *id* is a decimal number **n**, the **n***th* device returned by the server is used. If it is a hexadecimal number (starting with *0x*) it is used as the resource identifier of the desired device. Otherwise, *id* should be the exact device name (e.g. Stereo Channel Output). You can use *auinfo* to query an audioserver for this information.

- **-interval** *seconds*

  *aupanel* queries the device attributes in regular intervals with a default length of **10** seconds. With this option a different interval length can be specified. Using an interval length of **0** disables the automatic querying.

Additionally, options from the Athena Widget Set can be used.

## AUPANEL AND THE ATHENA WIDGET SET

*aupanel* uses the X Toolkit Intrinsics and the Athena Widget Set. For more information, see the Athena Widget Set documentation.

## ADJUSTING DEVICE ATTRIBUTES

To adjust the attributes of a device, select the desired device from the **Devices** menu.  The device gain may be adjusted using the **Gain** slider.  If applicable, the device input mode can be toggled between *Line-In* and *Microphone* by clicking on the appropriate box.  If applicable, the device output mode can be selected by clicking on the *Speaker*, *Headphone*, and *Line-Out* boxes.  Some output devices may support combinations of these selections.

To query the current device attributes, click on the **Query** button.

To mute (resp. unmute) the current device, click on the **Mute** button.

## ENVIRONMENT

In addition to the standard toolkit environment variables, the following environment variables are used by *aupanel*:

- **AUDIOSERVER**

  This variable specifies the default audio server to contact if *-audio* is not specified on the command line.  If this variable is not set and the *-audio* is not specified on the command line, *aupanel* will attempt to connect to the audio server running on the X Window System display.
