* Can I specify the pulseaudio "application name"?

Sometimes I play sounds from commandline with the 'play' command. This
shows up as a pulseaudio stream (aka 'sink source') named "SoX". I can
adjust the volume for that stream separate from others on my system,
no problem.

But what I'd like to do is have some set of these (eg: notification
sounds) be a different volume from others (eg: all the rest). So, I
thought maybe there's some way to specify a pulseaudio application
name other than "SoX" (maybe "SoX-my-notifications", or somesuch).
Then, I can adjust the volume for that separately, and pulse will
remember it.

But so far, I haven't found any way to do this.

Anyone know if this is possible?

I made a SO post here with some more details:

Thanks

There is currently no way to set the name.  It is hard-coded here:
https://sourceforge.net/p/sox/code/ci/master/tree/src/pulseaudio.c#l65

If one made a copy of  sox.exe  and used a binary editor, could one
alter the 'sox' literal that's inside the .exe to something else
and still have it work?   Or will the literal that's used for this
purpose also be used for other parts of sox?

(I appreciate that even if it's possible it might not be easy to find
the right instance, if there's more than one, inside the .exe ... and
if the .exe does any checksumming of its own contents to ensure it's
not corrupt, this would break that too).

Ah, too bad it's hardcoded.
Yeah, I suppose outside of hex editing the binary another option would
be creating my own 'play-xyz' command that uses libsox to do the heavy
lifting. Maybe with a python wrapper of libsox, or similar.

Thanks

Wouldn't it be simpler to edit the source code and build it yourself?
