Is it really possible to know exactly, every time, at what level the sum of the audio streams are? IIRC float point does avoid some issues. However, do you think it's smart to adjust at least two following instances within the same audio chain at the same time?
If talking about adding two signals, whatever they are, if you know how the sum is made, you can know what the worst case sum will be and if that will cause any problems.
Ok, I believe this without verifying it. So I still don't know, but I buy it as truth for this moment.
By knowing the inputs and the process, the sum in this case, I don't see why it would be a problem to change several things at the same time, you just need to be careful not to get problems.
Hardware steps vs software steps? I Don't believe that it's possible to automate it. Assumed the ALSA driver does come with everything PA needs, I still don't believe that it's smart to do it that way. "Careful" vs straight, but "careful" implies a delay. Analog forgives little mistakes, digital doesn't. Not everybody wishes to be the sun of a gun. I prefer to be careful, when "using/consuming" audio. Regards, Ralf
