Nope, I read that page. There is no mention of 'sun:x' in that page. There is, however, a reference to 'rsnd/0' being 'First hardware audio device', but trying it and having it fail (before learning of '-z nframes' option) brought me to misc@. I think this can be documented better in aucat(1) with a concrete example or two. --patrick >> Googling finds old (google-cached) current.html pages, circa 2009, >> suggesting using 'aucat -f sun:1' for /dev/audio1.
