[alsa-devel] wrong decibel data?

[Nicolo' Chieffo]

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
