So this happens with gst-launch? What pipeline exactly? Using what mp3
decoder? Does it happen just with that one particular mp3 clip, or any
mp3 clip, or any audio file (wav, aac, vorbis, flac?). Does it happen
with audiotestsrc?

Why do you think "some part of the gstreamer/alsalib makes the hardware
to lower the volume" ? Do you see the hardware mixer settings change,
e.g. in the alsamixer application? GStreamer/alsasink don't mess with
hardware mixer settings usually.
