 NAME    [Toc]    [Back]
      Aserver - start the audio server

 SYNOPSIS    [Toc]    [Back]
      /opt/audio/bin/Aserver  -f

 DESCRIPTION    [Toc]    [Back]
      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    [Toc]    [Back]
      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    [Toc]    [Back]
      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 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    [Toc]    [Back]
      The Audio Server must run on a system that has audio hardware.  Note
      that HP-UX for the 8MB 705 System does not include audio software.
