Deep Sleep not working using Audio Library

[ajay.dusa]

I am trying to establish ‘DeepSleep’ in my code, but I am unable to do it. The Teensy Board does go to deepSleep mode(USB and other digital pins get disconnected). But it consumes 35mA which is huge. I know the problem is because of the Teensy Audio Library, I tried without the Audio Library on the same board it consumes <5mA which is what I want. But with the Audio Library I am unable to get. I tried each and every technique also read lot of forums but couldn’t get what I wanted.
The code works as follows, List of songs get played once a day. For Time keeping I am using Teensy internal RTC with external crystal attach to it.
Please if you can find any error in my Code please point it out.

Hi,

You seem to turn I2S off for the audio (logical when going to sleep) with:

  SIM_SCGC6 &= ~SIM_SCGC6_I2S;

but never seem to turn it back on when you wake up with:

SIM_SCGC6 |= SIM_SCGC6_I2S;

cheers
