How do I increase / decrease the volume coming from speaker out? Is there any hardware control or software control for this?
you can tune the volume by voice control. E.g: you can say: 'Alexa, volume six' (volume rang:1~10)or you can say: 'Alexa, volume up/down'.
Ah ok thanks Seven.. It worked well !!
I thought that is down to the hardware or software of the WisCore / Wis audio board..
