Qwiic Speaker Amp Responding Slow
By default, the TPA2016D2 can take a few seconds before changes to its configuration are applied. Try following the application note in example 1 to disable the limiter, disable the noise gate, and adjust the release/attach values to 1. The changes are not saved upon every power cycle. If power is removed from the Qwiic Speaker Amp, you will need to send the configuration again.
No Sound from Speakers
Not hearing any sound from either speaker? Try checking your connections and ensuring that the are secure.
- The thin wires attached on the thin speakers might not be fully in the screw terminals.
- If you are using alligator clips, make sure that they are not touching the speaker's frame. The 8Ω small, cone speakers do not have a lot of space between the tabs and its frame. A small bump may cause the alligator clips to touch the metal frame, cause a short, and damage the amplifier.
- Make sure that there is a sufficient power supply connected to the board and the PWR LED is lighting up (assuming that the jumper is still closed).
- Make sure that the TRS cable or wires are fully connected to the audio source.
- Check the volume and ensure that it is not set to 0 on your audio source.
- Make sure that there is power applied on the audio board.
