Hi,
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?
Hi:
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。
