First please change license section into this one (https://fedoraproject.org/wiki/Licensing:Main)
License: LGPLv3+,CC0,BSD
Second you're not installing via "cmake" file and since you're were only copying "sound" files as installation, which means we can remove these BR(s)
BuildRequires: extra-cmake-modules BuildRequires: cmake BuildRequires: qt5-qtbase-devel
Also %build section is empty which means we don't need no debug variable as well
# debuginfo.list ends up empty/blank anyway. disable %global debug_package %{nil}
And we make it "noarch" since this is just a "sound package" It is not depend on any arch as well.
BuildArch: noarch
You're also missing license section in files so we need that to as well.
%files %license LICENSES/*.txt
