This is the second thread in which you've asked this.
I guess that no one bothered to answer because it's kind of obvious from the spec;
A quick Google and found the spec on E14 website and from it I extracted this:
- For use with Raspberry Pi
- Capable of rendering HD Audio, at 24-bit, 192kHz
- 3.5mm 4-pole jack for a headset/boom mic combination for gaming or VoIP applications
- Two DMIC microphones onboard for stereo recording
- 3.5mm jack for Stereo Line Input for high quality audio recording or capture
- 3.5 mm jack Stereo Line Output for connection to devices such as external stereo amplifiers or powered speakers
- Stereo Digital input and output (SPDIF)
So no speakers.
The Cirrus Logic Audio Card , is the only one compatible with a pi3, as for its 40 pins GPIO bus.
The Cirrus Logic Audio Card , has its on board amp, capable of driving 2 speakers at about 3 watt per channel.
However these pins are not soldered on from the factory, and must be done yourself.
If you have the card and the skills, I advise you to do so and test it. The usecase scripts are provided.
So quite obviously no on-board speakers on this card , but an on-board speakers out circuit is provided.
I do not own a wolfson card, but they could be very similar, for the 1st generation raspberries of course.
