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
