I just had a discussion with pulseaudio developers in which they told me that if the speakers don't emit any audio when the ALSA volume is 0%, then the correct gain value should be -inf dB (a value lower than -200 for pulseaudio means mute). Unfortunately my card has -48 dB.
They also said that if with -47.25 dB (which is what I get with ALSA volume set to 2%) I can hear audio even if it's very very low, at -48 dB I should still be able to hear something (the scale is logarithmic).
Their request is to change to -200 the gain reported from my card driver when the ALSA volume is set to 0%. Thanks
