I think you're basically asking about "port" priorities and "sink" priorities here? If so there is no relationship between the two. The priorities here are used to determine what is selected as default/initial values when no configuration files exist. That is we will attempt to use the most obvious settings when the user logs in for the first time. i.e. we'll use the built-in sound card and not the HDMI on a laptop (using sink priorities) and we'll use Speaker output and not Headphone (using port priorities). If this isn't what you're talking about, then apologies :D All the best 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/
