NAME
Aserver - start the audio server
SYNOPSIS
/opt/audio/bin/Aserver -f
DESCRIPTION
The Aserver command starts the HP-UX Audio server, which can run on a system with audio hardware.
See Audio(5) for information about which systems have audio hardware. The
-f option forces the starting
of the Audio server; this option is only needed if the Aserver has problems starting.
The Audio Server
Before using any audio tools such as the
Audio Editor, the system or X station must be running two
audio server processes, called
Aserver. On a Series 700, the Remote Procedure Call daemon (
rpcd
)
must also be running.
Normally, the Aserver processes and
rpcd start automatically when the system is booted. If problems
occur on an ENTRIA or ENVIZEX X station, see the X station owner’s manual. On a Series 700 Audio
hardware, first check if rpcd is running. Type the following:
ps -e | grep rpcd
If it is running, you see a line similar to the following.
604 ? 0:36 rpcd
If it is not running, see HP 9000/DCE documentation for information on restarting it. If
rpcd is running,
verify that the Aserver is running. Type:
ps -e | grep Aserver
If the Aserver is running you will see lines similar to the following, which indicate the presence of the two
Aserver processes:
1 ? 0:00 Aserver
224 ? 0:00 Aserver
If it is not running, become root and restart it as follows:
/opt/audio/bin/Aserver
If it fails to start, reissue the command with the -f option:
/opt/audio/bin/Aserver -f
Using Audio over the Network
From a workstation, you can also use the Audio Editor and Control Panel over the network. However, the
remote system is where the actual playback and recording occur.
The local workstation (or audio client) can be any Series 700 system. The remote system (or audio server)
can be a Series 700 or an X station with audio hardware and must have the Aserver processes running. If
the server is a workstation, it must also allow access from remote clients (see asecure(1M)) and must have
rpcd running.
To make the system an audio client, set the AUDIO variable by modifying the $HOME/.vueprofile
file as follows:
Korn, Bourne, and POSIX Shells: AUDIO=system_name; export AUDIO
C Shell: setenv AUDIO system_name
For system_name, identify the workstation or X Station running the Aserver.
If the AUDIO variable is not set, the Audio Library attempts to use to the Aserver on the system defined by
the DISPLAY variable. If neither DISPLAY nor AUDIO is set, the Aserver on the local machine is used.
DEPENDENCIES
The Audio Server must run on a system that has audio hardware. Note that HP-UX for the 8MB 705 Sys-
tem does not include audio software.
