I'm not sure there is a way to handle this really. Either we want volumes per-port or we don't. IMO we do (this is how it works on my iPhone for example) and I think from the various mumblings I've heard over the years most people want this type of functionality. But perhaps there is indeed some magic solution that we are both missing :p Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mageia Contributor [http://www.mageia.org/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/]
