Hi Wirrunna and Gildahl,
I am not an ALSA expert but I think it can be explained by the
difference of setting the volume to 100% versus 0db.
Code:
--------------------
tc@Akkordion:~$ amixer -c 0 -- sset PCM 100%
Simple mixer control 'PCM',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Playback channels: Mono
Limits: Playback -10239 - 400
Mono: Playback 400 [100%] [4.00dB] [on]
tc@Akkordion:~$ amixer -c 0 -- sset PCM 0db
Simple mixer control 'PCM',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Playback channels: Mono
Limits: Playback -10239 - 400
Mono: Playback 0 [96%] [0.00dB] [on]

regards
Greg
