Great. An updated patch is attached. For symmetry, I added this
option to the alsa source module as well.
The Ubuntu folks have customized pulse so much that it is difficult
for me to get this version working on my system. For this patch I
have only made sure that it compiles. But it does pretty much the
same thing as the one for 0.9.14, which is working great for me.

Yes we may be confused by case 2, but an odd setup (that still works in some capacity) for some people is probably worth it considering that many others will get a working setup automatically. But that's just my opinion. Perhaps we can have some kind of switch to enable how many outputs to probe which is, by default 1, but can be increased? That way we can perhaps expose this via the GUI somehow.

Currently PA selects one mixer element and then just sticks to it regardless which profile is activated. On some cards that works fine. On most cards however SPDIF is not influenced by "Master" and hence the volume control becomes useless. This needs to be fixed in PA.

This is problematic indeed. It is impossible for the driver to know which connectors of the chips are actually soldered properly to external connectors by the laptop manufacturer and which ones are not -- unless we had an external database which knows this. But honestly I believe that maintaining such a database is doomed to fail.

As you can see in that > screenshot the analog and digial outputs are exclusive... Yes, right now PA only checks the combinations of 0 or 1 inputs plus 0 or 1 outputs. Combinations of 2 or more outputs are not checked for. And there's actually a reason for this: Some sound cards allow devices to be opened multiple times (as in hw mixing). That way multiple programs may play audio at the same time with their audio being mixed in hw and output on the same connector. Now, it is not really possible right now to distuingish the case "Analog and SPDIF audio can be used completely independantly" and the case "The device may be opened twice but only either SPDIF or Analog can be used at the same time" -- because in both cases for PA it appears that opening the audio device twice works. > So while it's a step towards not requiring custom setups, it's not > completely there yet.

This is how I undestand profiles :) The problem is not that I had to manually specify two sinks in the config file. I don't mind doing that. The problem is that the only way for me to independently control the volume of the SPDIF was to create a custom mixer control using softvol. So I needed a way to select this as the mixer for one of the sinks. I tried installing the latest git sources on my Ubuntu Jaunty box but it just broke sound in all my applications. For my own purposes, I'm going to need to start with the Ubuntu-patched 0.9.14. However, if you are willing to accept this patch I will forward port it so that it applies to the latest sources.

AFAIK this really depends on hardware. Above screenshot is from my laptop (Centrino 2, Intel HDA on Connexant chip), I once saw this dialog on computer with EMU10K card. The list was bigger than screen and there were various combinations. So, if the card supports simultanous output to SPDIF and analog, there will be two ink available. This is how I undestand profiles :) Another funny thing, my laptop has only analog jack for headphones.

[pulseaudio-discuss] specifying ALSA mixer control
Hi,
My audio device has an IEC958 output as well as analog out. I set up
two module-alsa-sink's so that i can direct streams to either output,
but I found that I couldn't control the volume of each sink
independently. I was able to use asound.conf to create a softvol
control for the digital out. However, module-alsa-sink doesn't have
any way to select a particular mixer control. Since both pcms are
part of the same card they both end up using the Master control.
The attached patch adds an argument called "control" to the ALSA sink
module. If this argument is specified it tries to use that control.
Otherwise it uses the current method of selecting Master, with PCM as
a fallback.
Best,
Kyle
