Analog stereo Duplex means you get both a stereo input and a stereo output.
Analog Stereo Output means you get only a stereo output, no input.
Digital connections carry digital signals, so normally you wouldn't be
able to connect those directly to speakers or microphones.

Normally you would choose Analog Stereo Duplex.

Thanks for the answer :)


pavucontrol is practically identical to "Sound Preferences" that you
find in the volume control on a regular Ubuntu Install. Just mentioning.

Hm, you are correct, hadn't noticed it before.

What is it you're recording? What software are you using?

The source is flash-based streaming radios (that I can't record with vlc http streaming). To record I simply use Audacity.

So I guess that for this setup the "Analog stereo Duplex" is the preferable one?

Thanks again

Hello

I am a total noob when it comes to sound in linux. I have Ubuntu and I
was trying to record what I was hearing. I did it but I have a question.

I installed PulseAudio Volume Control (pavucontrol) and noticed the
"Configuration" tab, where it has an "Internal Audio" profile with
options like:
* Analog Stereo Duplex
* Analog Stereo Output
* Digital Stereo Duplex (iec 958) + Analog Stereo Intput
* Digital Stero Duplex (iec 958)
* Off

I tried to find more information about these options, but there is no
"help" for this GUI. SO I was wondering if anyone could give any hints
(links, documentation etc) on what these settings are.
