<![CDATA[core2 MBUS PIN for speaker output]]>Re: Speaker.Volume on Core2 Hi on the Core there is GPIO 25 for speaker out and there is nothing equivalent on Core2? The closest is GPIO2 as far as I can tell from the schematics but the output is terrible. Is there a software fix that can be implemented or is it a Hardware issue? Just wondering what would happen if I removed the amplifier chip from the Core2 board would that improve GPIO2?

It makes people want to use an external option but there is no option it’s actually a downgrade from the original Core.
