I assumed it had to be something hardware because a software control wouldn't work too well, just end up loosing information. I just got a new sound card, so I will play around and see if things are different.

Unfortunately it appears that the sink volume controls do not allow enough range (I think this would be dynamic range in audio terms). Basically, if I set the system up so 100% volume is as loud as I want things to go, 1% is not quiet enough. I have tried setting the sink volumes using pacmd where the range of volumes is 1-65535. A value of 0 is muted, but 1 is quite loud. Any thoughts/experiences on this? I'm contemplating setting both the stream and sink volumes so I can have more granularity of control. </pre> </blockquote> <pre wrap=""> PA tries to use the sound card volume control if possible. However most sound cards only a allow a limited range of volume control. With many sound cards the lower volume boundary does not result in total silence. I will eventually add support to PA that we can extend the volume range to the same dB range on all machines, regardless of what the hardware provides. We can do this if ALSA exports dB information to us. Of course, each sound card as a maximum gain for the output. We cannot go higher than this, regardless whatever we try, unless we resort to dirty stuff like doing the amplification in software, which is most likely not what you want on 16 bit audio. May be some of the auxiliary controls of your sound card mixer also influence the final volume of your audio? You might want to play around with your ALSA mixer with alsamixer -c0.
