Most of the time I use my speaker out (or headphones) as my main output source. Previously I would plug in my TV (via HDMI) or an audio interface (via thunderbolt) then alt+click on the speaker, select the option and away we go. Now, for some reason, the options don't appear here (it has everything but the device I've just plugged in). If I go to settings the device I've plugged in is in there but clicking it doesn't do anything. The only way I can get it to work is to reset my rMBP while the device is plugged in, then it automatically picks up whatever device I have plugged in (it is also now there when I alt+click the speaker icon). When I unplug it I have to reset again to be able to use the internal output. This started happening all of a sudden. Any ideas? I'm on 10.10.3 I have tried the killaudio command but that didn't help.
