Hi Colin, Sorry for not making the question clearly. In alsa module, we parsed out alsa mapping information from profile-sets and mixer paths, and create sink from mapping, so I thought there should be same for mapping priority and sink priority, while port priority comes from mixer path/setting priority. I found port priority assignment in source code, but alsa mapping priority is never used, sink priority is only dependent on PA_PROP_DEVICE_CLASS, PA_PROP_DEVICE_FORM_FACTOR, PA_PROP_DEVICE_BUS, PA_PROP_DEVICE_PROFILE_NAME. So if I can't specify the default sink by profile-sets config files. 2012/1/4 Colin Guthrie <gmane at colin.guthr.ie>: > 'Twas brillig, and Feng Wei at 04/01/12 10:08 did gyre and gimble: >> Hi, >> In alsa module, I can't find a place to use alsa mapping priority. >> Should it represent sink priority so that we can statically appoint >> default sink when multiple cards/sinks exist? > > I think you're basically asking about "port" priorities and "sink" > priorities here? > > If so there is no relationship between the two.
