What is so strange? Two cases that may explain that behaviour:
* Alsamixer does not have a clue what is the maximum/minimum volume of the device. So setting volume ~0 does not actually sets the device to the minimum volume.
* Alsamixer defines incorrectly the relation between the master and PCM. That is, huge changes in the master may result in small changes in PCM volume: you change master from 50% to 0% (mixer) volume, but the PCM goes from 50% to 25% (real) volume.
