Would it be better to do all this in a new plugin, Yes. Yes. In ALSA, everything is a plugin. This is obvious with pcm plugins like dmix, but "hw" is a plugin, too (that just happens to access the hardware driver). For mixer controls and related stuff, there are ctl plugins. The only one so far is the "hw" plugin, which provides access to those controls implemented by the hardware driver. A volume scaling plugin would consist of a pcm plugin that would scale its input data before handing it off to a slave plugin, and of a related ctl plugin that would provide a virtual volume control and hand off requests for all other controls to a slave plugin.
