We had some sound related discussions today at the Ubuntu Developer Summit, which I just wanted to write down and share with you before I forget about it... 1) Icons per port The new sound settings UI exposes ports as its primary object and as such it would be nice to have one icon for the Headphones port and another icon for the Speaker port. From what I can tell this would be quite simple? As Tanu has written infrastructure that can take port properties from the path .conf file, and that is then exposed to client. 2) +11dB The people within the discussion - including myself - seem to mostly agree that for the sound settings UI, it makes most sense to remove the possibilty to set more than 0dB output for the device volume, but instead allow it for stream volumes. The argument is that the most common use case for this is that you're listening to DVD/flash movies, where the particular application would be what's bothering you. Therefore it would make more sense to boost the application, rather than the device. 3) Some questions were raised about PulseAudio's ABI stability. I think we're pretty hard on not introducing anything that breaks the ABI for clients, ever, but what about modules? I'm assuming that since modules can call into the core very arbitrarily, we would not assume any kind of ABI stability for modules, not even between stable releases (1.0 to 1.1, e g). Is that correct? I e, if I compile a module against 1.0 and distribute the binary, once PA 1.1 is rolled out, there is a possibility that my module will crash PulseAudio unless the module is recompiled against 1.1. // David
