As I was trying to fix an input device empty list issue in guvcview, I solved it by raising an alsa flag on portaudio. Maybe the guvcview deserves an alsa flag in order to onstrain in on portaudio ... My apologises if it does make sense at all.
I vote INVALID, since the package itself does not use ALSA directly in any way and does not need to be prepared for ALSA use in any way. From the HOMEPAGE: "All interfaces (ALSA, OSD, JACK, ...) supported by portaudio should be available in guvcview. Just make sure portaudio was compiled with the desired interfaces enabled."
