[ANNOUNCE] New Mixer Handling in PA 0.9.16/F12

[Doug Ledford]

CD in is nothing more than an analog input. PA ignores all the analog  
inputs other than as a digital PCM source. Treating all the analog  
inputs as digital sources and not allowing the hardware to mix them to  
output has various drawbacks. I've just been covering some of them.

I'm out and about and using my phone to send this, so no long drawn  
out discussions are possible.
