I had it working at home, but when I installed the switch at the bookstore, there is nothing to be heard on the audio ports. Now I'm trying to debug it remotely, which is difficult because I can't hear the speaker.

The system is an HP ProDesk 400. It has a "Audio-out/Audio-in combo jack" on the front panel. It has an "audio-in" jack, and an "audio-out jack for powered devices" on the back. When it was working at home, I plugged powered speakers into the audio-out jack on the back.

I have no idea what most of his is, and the HDMI in the list is confusing, because the system has a DisplayPort connector, but no HDMI.


I assume device #0 is the connectors on the back. I also assume that when it bridge to "portaudio/auto_answer" that it will use the only device that is configured with a "o", which is device #0.


One difference between home and the current location is the addition of a 10' audio cable between the computer and the speaker, but I can't see how this would make a difference.


An advanced question is how to use a portaudio microphone. I plugged a microphone into the "audio-in" on the back, but this isn't working either. Is this because that port needs line-level audio? The HP manual says the front audio panel connector can be used for a microphone. Is that portaudio device #1? How to I configure that device for input?

I figured it out.
The 1st problem was the volume was set to 0. In order to fix that, logged into the server and brought up a Gnome desktop, then used the audio tool to raise the volume.


The 2nd problem was that when I plug something into the front audio port (which is supposed to be able to be used for both a microphone and a headset), the audio stopped being sent to the speaker, which was plugged into the audio out jack on the back. Unplugging from the front audio jack solved that problem.
