# Once replacing system JACK libraries is possible, it's likely that
# jack-client IUSE will need blocking to avoid users accidentally
# configuring their systems to send PW sink output to the emulated
# JACK's sink - doing so is likely to yield no audio, cause a CPU
# cycles consuming loop (and may even cause GUI crashes)!
# - TODO: There should be "sound-server? ( || ( alsa bluetooth ) )" here, but ALSA is always enabled
# - TODO: Pulseaudio alsa plugin performs runtime check that pulseaudio server connection will work
# which provides adequate guarantee that alsa-lib will be able to provide audio services.
# If that works, pulseaudio defaults are loaded into alsa-lib runtime replacing default PCM and CTL.
# When pipewire-alsa will be able to perform similar check, pipewire-alsa can be enabled unconditionally.
# - ffmpeg is only used for pw-cat. We don't build the spa plugin which receives barely any activity.
