It *might* be useful for some people to have portaudio support, but we
don=E2=80=99t usually add all supported audio backends.  We don=E2=80=99t=
 even always
add pulseaudio to the inputs, because pulseaudio can readily deal with
programmes that only use the ALSA backend.

I=E2=80=99m not using pulseaudio; for me it=E2=80=99s just ALSA for regul=
ar software +
JACK for =E2=80=9Cprofessional=E2=80=9D audio where sync and timing matte=
rs.

I=E2=80=99m not very knowledgeable about pulseaudio, unfortunately.  As
pulseaudio can manage audio streams using various different backends
from pulseaudio-agnostic software, what really is to be gained by adding
pulseaudio to the inputs?  AFAIK using pulseaudio directly is not much
different from using ALSA and configuring pulseaudio to manage this
stream.
