Simultaneous playback and recording at 48Hz 6 ch #43

Hi!

I know I may be pushing the boards to its limit, but I have flashed the 48Hz 6 ch firmware and also output the sound while recording (the output is not connected to a speaker, but I am sending the same sound to it that is on a real speaker to achieve AEC. Well, sort of). However it looks like the board freezes when I try that, and stops responding untill I power it off. Record only works fine, and the 16Hz firmware also works fine with this regards.

Please advise.
