Created attachment 777260 [details] Output of `emerge --info` Hi, I wanted to load the module-virtual-surround-sink module and the module is not present in my system: ``` $ pactl load-module module-virtual-surround-sink Failure: Module initialization failed ``` The system logs state the following: ``` May 7 12:07:14 <host> pulseaudio[3983]: [pulseaudio] ltdl-bind-now.c: Failed to open module module-virtual-surround-sink.so: module-virtual-surround-sink.so: cannot open shared object file: No such file or directory May 7 12:07:14 <host> pulseaudio[3983]: [pulseaudio] module.c: Failed to open module "module-virtual-surround-sink". ``` The source files seem to be present in the package sources under `pulseaudio-15.0/src/modules/module-virtual-surround-sink.c`, so my guess is that we are missing some macro define or build system setting. Maybe we are missing other modules as well, this is just the one I was attempting to load at the time.

FFTW dependency will be explicitly pulled if you have USE 'equalizer' otherwise fftw will be detected and used if installed. This implicit dependency looks like a bug so probably needs to be treated somehow. I think adding USE fftw to pulseaudio daemon ebuild and making it behave to enable 'fftw' feature of pulseaudio daemon is a good way forward (that is, either USE 'equalizer' or USE 'fftw' or both will enable FFTW.)
Apologies, I have been inactive here for some days now. Thank you very much Igor, I see the pull request is waiting to be merged against master. I really appreciate you sharing the workaround and fixing the ebuild.
