Want to have looping white noise on my tablet. Generate noise in audacity, adb push to tablet, play, works, but doesn't loop. Can't figure out how to loop. See hangouts_message.ogg and hangouts_video_call.ogg on tablet already, notice that hangouts_video_call.ogg loops. Aha! Must be ogg metadata or something. Google. Find http://forums.rpgmakerweb.com/index.php?/topic/10987-make-looping-bgm-part-1-ogg-vorbis/ . Edit metadata of my .ogg to include LOOPSTART and LOOPLENGTH. Does not loop. Inspect hangouts_video_call.ogg. Has metadata field "ANDROID_LOOP"=true. Of course. Add this to my .ogg, play on tablet, loops... but with a clicky pause. Bummer.
Solution: give up and install audacity on laptop, I'll just hook my headphones directly up to it, I guess.
