I have a new 3.5 and cannot get DAC1 to work. DAC0 works with great volume and clarity.
i used WaveFilePlayer with minor mods to reference the use of the analog out.
The Teensy is connected to a MAX9744 20W amp. Both channels on the amp work.
Swapped Capacitors to confirm that one is not bad.
Checked voltage. Working DAC0 shows about .5V while playing.
DAC1 - none.
Have used the Audio shield with success (not related to this...), but this is my first attempt at audio out with on board DAC and not sure if just doing something stupid.
Attached is pic of setup and program.

Thanks,

To utilize both DACs on T3.5/3.6, I think in your sketch you want AudioOutputAnalogStereo in place of AudioOutputAnalog -- maybe go back to the design tool gui and select "dacs" instead of "dac"

Using "AudioOutputAnalogStereo" works! I know have stereo...
Thank you...
