I'm just trying to implement a volume control using the Alsa mixer API.
That works already with plain ALSA but not if PA is used.
When using plain Alsa I'm getting the PCM mixer to work while with PA I 
found there is only a Master mixer available which I can get but the 
volume get functions are returning strange values.
I'm using
The range looks suspicious (1-140576480) but the reported volume is 0 
what makes no sense.

So do I need to do something different for PA or won't it work anyway?
