Change number of channels at runtime

[shogun_panda]

Hi! I have an Acer laptop which ships an Intel HDA sound card. This cards support both 5.1 and 2.0 output (which I can manage with channels option), but in former case I have to use all 3 jacks (output, line-in and mic-in) to obtain 5.1 output. When I want to plug a mic or any other device in mic-in or line-in jacks, I have to switch to 2.0 mode. With ALSA, this could be done with a switch in the mixer. Unfortunately, PA doesn't seems to support this and I have to restart the server (or reload the module) every time to reflect this change. Should be channels numbers be modifiable at runtime?
