Low audio output on Respeaker 2mic hat


I’m using the Respeaker 2mic hat and I have plugged in a speaker into the JST 2.0 connector however the audio output is low. When I test the headphone jack, the audio is very low, almost inaudible. I have checked the settings in alsamixer and the all volumes are set to full.

When I use audio PWM output using my own amplifier and speaker I get a much louder volume. Is there anyway to increase the audio volume that is output from the speaker?


You can configure sound settings and adjust the volume with alsamixer. After you text "alsamixer: in the command window, please press F6 and select seeed-2mic-voicecard. And then choose or to set volume。
