<![CDATA[M5StickCPlus No Sound from Internal Buzzer]]>I must be missing something but I cannot seem to get any sound out of CPlus internal buzzer. I'm not sure if the Speaker Commands pertain to the internal buzzer or only the external hat speaker. I am using UIFlow but can do an Execute command if necessary.

I have been playing with the Core2 for awhile but just got a StickCPlus today so a little clueless regarding it.0_1623037695118_Sound.jpg

Any suggestions would be greatly appreciated.

Thanks

Here is a project I built with the M5StickCPlus that uses the buzzer.

I set freq=100 and duty=0

So, can someone tell me how to get a usable audio level out of this little buzzer.
