There's an error in the ebuild logic that prevents rmedigicontrol from being built unless both rme32 and rme96 USE flags have been enabled, when either flag should've worked. Patch for ebuild attached below. Reproducible: Always
Created attachment 114591 [details, diff] Patch for the media-sound/alsa-tools-1.0.14_rc3.ebuild
Sorry for the delay, thanks for the patch!
