HP Remote Graphics 4.2.0 User's Guide

With ALSA working, users can validate JACK by performing the following

steps:

1. Ensure that the ALSA device is properly configured and can be heard

through the desired port, i.e., headphone jack, speaker, etc.

2. Determine that no other jackd process is running:

3. ps -ef | grep jackd

The following steps connect a simple beeping client to a JACK sound server

daemon:

4. jackd -d alsa hw:0 & # start jackd

5. jack_metro -b 120 & # audio client

6. jack_lsp -c # display connections

7. jack_connect "metro:120_bpm" \ "alsa_pcm:playback_1"

Note: jack_lsp may suggest an alternate PCM playback channel based

on your hardware - use that for the jack_connect command

6. Cannot connect to running jackd process on Lunux Receiver:

You may not own the executing sound server process (i.e., your user Ids

(UID) may not match). Currently JACK systems only support client-server

combinations where the UIDs match. If UIDs do not match, you will often see

a client connection failure message:

jack server not running?

Troubleshooting Remote USB

HP Remote Graphics Software supports a Remote USB capability. This allows a user

to connect any number of USB devices to a local RGS Receiver system and have the

devices appear connected to the RGS Sender system.

Currently only a single Sender can receive the Remote USB device connections. If

you have problems connecting a Remote USB device, the following checklist may

help to identify the problem:

1. HP Blade Workstations Only:

Remote USB is only supported on an HP Blade Workstation Client receiver

system connected to a HP Blade Workstation sender system. In addition, the

Sender and Receiver versions must match. See the USB Remote

Requirements section for further details.

2. HP Remote Virtual USB Driver:

Verify that the HP Remote Virtual USB driver is installed and active on the HP

Remote Graphics sender system. Open the Windows XP Device Manager and
