<div dir="ltr">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.

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.

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?
