[alsa-devel] [PATCH] Add support for gain in softvol plugin

What do you think of this patch? I tested this using a stac9205 HDA
codec with all sample formats supported by softvol (s32, s16, s24, big
and little endian).
The potential drawback I see is that softvol now has to use a
intermediate long long multiply and add when computing amplified 32-bit
samples. This wasn't an issue with the system I tested on, but possibly
could be on slower machines. Also, are their any portability issues with
using a long long datatype in alsa-lib? What is the list of embedded
architectures that alsa-lib is targeted to build on? I see long long
used in many other places in alsa-lib, so I'm hoping this isn't an issue.
