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
nth 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 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.
