Could this maybe explain why pulseaudio was having such problems with alsa with regards to gain controls????
I don't think so since no soc user report wrong dB range
http://www.pulseaudio.org/wiki/WritingVolumeControlUIs
If the flat volume model of PA is 0% to 150% , this mean that alsa-lib does not provide any DB scale suitable for PA to implement dB info for the pulse device as DB_LINEAR require max is 0dB ( at least capture stream must have gain )
only one of the PA developer complain about his HDA codec has incorrect dB range but not willing to provide alsa-info.sh
There is a patch which may affect the dB scale
