A different approach would be to copy the /lib/systemd/system/bluetooth.service file to /etc/systemd/system.
This provides an override to the system default file which may be overwritten on an update.
Then add the ExecStartPost= directive to the Service section.
See https://www.freedesktop.org/software/systemd/man/systemd.service.html for details.
Its usually better to use this: systemctl edit bluetooth.service
and then just add the lines that you need to override.
[Service] ExecStartPost=/usr/local/bin/fixaudio.sh
this creates a drop in file that means that you do not have to worry about any improvements to bluetooth.service that could be updated by fedora.
