Ugh, why don't you use home-pipewire-service-type?

Packages are file-like, i.e. replaced with their location when 
used in g-exp.
Here is an example how to define the configuration, I've adapted 
it from gnu/home/services/home.scm

--8<---------------cut here---------------start------------->8---
(simple-service 'pipewire-configs 
home-xdg-configuration-files-service-type
 `(("alsa/asoundrc")
   ,(mixed-text-file
       "asoundrc"
       "<" pipewire "/share/alsa/alsa.conf.d/50-pipewire.conf>\n"
       "<" pipewire 
       "/share/alsa/alsa.conf.d/99-pipewire-default.conf>\n"
       "pcm_type.pipewire {\n"
       "  lib \"" pipewire 
       "/lib/alsa-lib/libasound_module_pcm_pipewire.so\"\n"
       "}\n"
       "ctl_type.pipewire {\n"
       "  lib \"" pipewire 
       "/lib/alsa-lib/libasound_module_ctl_pipewire.so\"\n"
       "}\n")))
