Yeah. I don't expect it to be 1:1 analog, but this is what I mean by not having something else to compare to. > I'm going to ask on LQ tomorrow morning.

Echo test: hearing the microphone If you are unsure about your microphone setup, you can hear the input from the microphone in real-time by enabling the loopback module <https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/#index57h3> (source <https://answers.launchpad.net/ubuntu/+source/pulseaudio/+question/83742>): pactl load-module module-loopback The module will show up in the *Recording* tab of the pavucontrol <http://packages.debian.org/pavucontrol> program, where the source and volume can be configured. While latency should be low, it should be sufficient to get a feeling of the sound quality as you will hear yourself speak in the microphone. To make the change permanent, add the following line to your ~/.config/pulse/default.pa: load-module module-loopback Watch out for feedback! Be ready to lower all volumes in case the microphone picks up the output from the loudspeakers. Naturally, it is better to run such a test with headphones. On top of this above technique, many conferencing services have built-in echo tests. For example, ? <https://wiki.debian.org/Skype>Skype has an echo test. ? <https://wiki.debian.org/Mumble>Mumble can also be configured to echo audio back (from local or remote) through the Configure -> Settings -> Audio Output -> Loopback test. \ https://wiki.debian.org/PulseAudio#Sound_level_is_low_or_suddenly_becomes_too_loud _______________________________________________ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
