hi
i just bought a speaker pHat from maplin i did the soldering i check continuity everything fine, i install the software i test with the test.py script the Vu meter work but the speaker didn’t. on booting process i heard a crackling noise from the speaker but nothing more, i try to see if it was detect on the i2c bus with i2cdetect cmd but no address for the pHat
If the speaker is crackling it’s getting power, the soldering looks okay, and the software setup looks okay.
There are a couple of joints on your header that could do with a slight retouch. Perhaps go over it carefully reheating the joints until they flow into little cones without adding any new solder.
i just reinstall a fresh copy of rasbian jessie lite, did the setup but still received the same msg « device or resources busy.
but i try something else i went in the file speakerphat and i try the cmd aplay test.wav and the vumeter and the speaker was working but with the mp3 file its a big fail :/
Hello, I am new to the forum.
I have a similar problem: I have two raspberry pie zeros and two Speaker pHat boards.
The one is soldered on directly, the other is distanced a bit, by only using short wires for the 7 connections. The two pies run the same raspbian image, and the phat works fine one Pie one, with sound and light. On pie 2, I can sometimes when I boot, get a little light, that disappears again.
I get a really weak distorted audio, and no lights.
I started with a rather thin wires, and have now changed to thicker wires and re-soldered them twice.
I tried a different speaker, with same result.
I tried adding power to both USB ports to make sure it was not under-powered.
Since the two pies are the same, and the OS/installation is the same, then it must either be;
The speaker pHat board umber 2,
Or my wiring/soldering.
I don’t know how to solve this. Does anyone know which of the 7 wires that would be susceptible to bad soldering/noice?
