Any ideas what might be causing this?
Are the sound generators on your workstation jack clients or pulseaudio
clients? In case of the latter, maybe you just need to set pulseaudio
mixer levels, for example with pavucontrol.
Ya that too. I had not thought of the possibility that pulse clients might
be a part of this... but aside from tweaking more than one control on the
alsa side, pulse also has a gain stage of it's own. Pulse's levels can be
changed by the client program which may not seem like a big deal... except
for programs like Skype that use these levels for AGC rather than their
own gain stage. This means the pulse level while using such a program may
change on it's own depending on room noise for echo/feedback cancelation.
