3 years ago The Crowpi2 is a platform for the Raspberry Pi more than a laptop.
It has no builtin audio. There is a squeaker and a vibrator, but no speaker. If you want sound, I would recommend a bluetooth dongle and bluetooth speaker. The "Happy Birthday" app can play tune on the squeaker, but I would not call that audio.

3 years ago I saw the headphone jack and figured there was a DAC involved. This page says it has stereo speakers. https://www.raspberrypi-spy.co.uk/2020/08/crowpi2-raspberry-pi-laptop-and-learning-platform/

3 years ago Yes, there are a pair of stereo speakers near the front on the bottom and they do works.
FYI, there is an official forum which monitored by the Elecrow tech supports. So, I recommend you registering an account and then post your questions/issues there. I don't see them response here often.
Also, there are FAQs posted there as well.

3 years ago If you are not getting sound out of the speakers, right-click on the Volume icon at the top of the screen and check that the Audio Outputs is set to 'HDMI'.
Also, take a look at this forum posting or here.

3 years ago Thanks. I discovered that the included speaker-test utility works well to test the speakers. My problem ended up being poor wifi (possibly a Pi radio issue) that was cutting out and dropping my Youtube test.

For example, try "speaker-test -t sine -c 2 -s 2 -f 1000" to play a 1 kHz tone out the right speaker.
Brand new CrowPi2, no hardware changes and no software installed. I got wifi going intermittently and tried to play something on Youtube and hear nothing. Is this likely a software issue with whatever OS version came on the microSD? What hardware connections can I check? Is there a good sound check utility to verify correct operation?
