I downloaded the app and had music streaming to the Apple Airport Express just fine and as soon as I went to the talkback-mic app the music stopped but the talkback app produced no audio,, yes I am pushing the big red talkback button and I too saw the "clumsy looking" instructions about turning on airplay.
So for me ,, it ain't workin'
This free app screwed up my 3rd generation iPad and had to reset it.
After trying to use this free talkback-mic app unsuccessfully the only options in the airplay button was changed from the two choices which have been iPad & Airplay, now it is Airplay and headphones. The music app still streams audio to the Airport Express fine but the iPad no longer is able to play music through the speaker. Only option was to reset the iPad. So much for free. Kevin, I understand it worked for you but not here.
I emailed the developer Mark with the following email
Hi Mark,
nice talkback app but I can not get it to work with my iPad 3rd gen.
I am using an Apple Airport Express to stream music during breaks with my Mackie DL1608.
Music is streaming and Mackie's Master Fader app is working great and I see audio level on the meters of the Talkback-Mic app but
I suspect it has something to do with "mirroring" what is mirroring?
As soon as I get this working I will cheerfully send you a PayPal offering.
Thanks,
Dan
