 Replying to [comment:16 howl]:

 > First I will tell you that your approach is failing with this, with your
 auto profiles make by combination I can select "Output Digital Stereo
 (IEC958) + Input Digital Stereo (IEC958)", when the same alsa-mixer has
 and switch to turn the iec958 in output or capture mode, then your system
 to detect if profiles combination works fails, al least is some hardware
 like the one included in M3N78-VM, I said this before.

 Sorry, I cannot parse this paragraph.

 > The idea is start selecting the sound card to configure, then the output
 (this could be called device as we could configure also inputs). We could
 enable or disable the selected output and also set the number of channels
 of it. The test button doesn't need explanation, something like speaker-
 test. The Remap button could be used for situations like the one we have
 with the hdmi now a days, you press the Remap button and then the first
 speaker starts to sound, then the user must click the corresponding
 speaker in the picture, when finished the mappings should be ok. An
 interactive and easy way to remap a device, the remap could be saved in
 /usr/share/pulseaudio/... in a file called "devicename.conf" with the
 corresponding rules to be applied only to the pertinent device.

 are playing sound in Analog for example and select another self-made
 profile that have multiple outputs including the Analog that is already
 with applications active on it, sometimes applications lost the stream
 sometimes not, with the system I'm proposing this shouldn't happen, if I
 want to Enable HDMI should not affect the other outputs.

 I am not really convinced that exposing too many UI options here is really
 such a great idea. Also stuff like channel testing is already being worked
 on in g-v-c.

 Please understand that my interest in hacking and beefing up pavucontrol
 is rather minimal. g-v-c is the way to the future.
