No, really quite definitely not. 0 dB means no attenuation of amplification. How loud that actually ends up is very much dependent on what's _behind_ your line-out. In this specific example, the cs4236 master is split in a digital part -60 dB to 0 and an anlog -34,5 to +12. I most certainly want "0 dB" to mean no analog amplification (nor (digital) attenuation, but the analog is what I want to know) is being done. And "Reply-To" from my previous message should be "Mail-Followup-To". Please kill that.
