Aserver(1M) — Series 700 Only

NAME

Aserver − audio server

SYNOPSIS

/usr/audio/bin/Aserver

DESCRIPTION

Beginning with Release 8.07, the Series 700 HP-UX operating system includes audio software comprised of an Audio Application Program Interface (AAPI) and selected example programs.

The audio software package contains client and server components, which can run on separate systems. Audio data can reside on still a third system. In all cases, however, the server must run on a Series 700 system equipped with audio hardware. (To determine the presence of audio hardware, check the hardware manual provided with the system or look for audio jacks on the back of the computer enclosure.)

To set up the audio software correctly and ensure that the supporting services are running, follow these steps:

Step 1. Start the NCS Local Location Broker Daemon.

Task 1. If you are not already super-user, log in as super-user.

Task 2. Enter the command line /usr/etc/ncs/llbd&. To make llbd start automatically at boot time, edit the file /etc/netncsrc and change the line START_LLBD=0 to START_LLBD=1.

Step 2. Reboot.

Step 3. Set the AUDIO environment variable to specify the node where the audio client should look for the audio server. If AUDIO is not set or if it is set to :0, the client connects with a server on the same node.

To specify that the client should connect to a server on another node, set

AUDIO = node_name: (Korn, Bourne, and POSIX shells)
export AUDIO

setenv AUDIO node_name: (C shell)

Step 4. Normally, the audio server starts whenever the system is booted. Check for the existence of the server processes by typing

ps -e | grep Aserver

You should see two Aserver processes. If the server is not running, start the audio server by hand by typing

/usr/audio/bin/Aserver

Then type

ps -e | grep Aserver

and check that there are two active server processes.

DEPENDENCIES

When an application program or the audio demonstration program uses the AAPI, the AAPI audio server component must run on a system that has audio hardware. Note that HP-UX for the 8-Mbyte Model 705 System does not include audio software.
