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
