What happened to Mute on audiosource for microphone?

I'm updating an old project to Unity 5 and have run into an issue with mic recording.

Previously you could mute the audiosource to stop the recorded mic signal from being output and creating a feedback loop. But now it appears if you mute an audiosource it will also stop playback, so mic input no longer works.

I raised a bug here: https://fogbugz.unity3d.com/default.asp?730079_cfbs38v9901f4ahu

The use case is real time pitch recognition and/or dsp where you don't want to hear the audio fed back.

Anyone else noticed this?

Edit:
It looks like it may not be a bug as such, but as part of the new AudiMixer system?
I can get around it by creating an AudioMixer group, setting that as the output for the microphone audiosource, then dropping the attenuation of the AM Group way down.

 

I'm experiencing the same, very annoying. sonicviz: Thanks for the workaround

 

TY a lot, you save my day.
