Disable gain in alsa

My experience is that alsa adds gain to a audio signal, if I dont run audio or video (MPD/MPV) to hw:x,y, the sound is noticably higher. This is annoying when I have adjust the volume when using youtube or spotify to play music instead of MPD for example.

Any idea on how I do that?

EDIT: I am NOT using pulseaudio and will never do that.

Re: Disable gain in alsa

It is a generic usb 2.0 soundcard, using default alsa settings supports no volume controller in alsa, is running MPV and MPD is running through hw:x,y which disables the gain, but for amarok, spotify, flash etc there is some gain added by default of alsa.

Then run everything by default to hardware through dmix (create your own).
