Hi folks, **SOLUTION: MY SOLDERING WAS AT FAULT! New SpeakerpHAT works perfect (after a lot of soldering exercises!)** Have looked through the threads - found no obvious workaround / solution in getting my SpeakerpHAT to sing… I’m running it on a Pi Zero W with latest Stretch-Lite distro. Soldering seems to have gone fine. I installed the ‘one line installer’ and ran ./test.sh. Output was as follows - ``` testing audio speaker-test 1.1.3 Playback device is default Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 96 to 1048576 Period size range from 32 to 349526 Using max buffer size 1048576 Periods = 4 was set period_size = 262144 was set buffer_size = 1048576 0 - Front Left 1 - Front Right Time per period = 3.176435 testing basic wav playback Playing WAVE './test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo testing text-to-speech testing VU meter ``` VU meter works fine, but no sound at all and no heat from the speaker either. **Any suggestions as to where to turn next?** Regards, Michael ---

I have to ask the obvious just to rule it out ;) Speaker jumper wires soldered in? ---

Soldering speaker with the supplied gauge wire was easier than the header. I’ll post a pic or two later… Anything else i need to do / . debug, get log file etc?? Cheers, Michael ---

On my Pirate Radio (pHat Beat) I ran the following sudo systemctl stop pulseaudio speaker-test -c2 -t wav I don’t know if you have to stop pulseaudio, I did at that time running I think Jessie. I need to keep better notes. ---

@alphanumeric Tried that, but only got the **smallest of feeble sounds** by having my ear right next to the speaker! Have attached photos of the soldering done - [https://photos.app.goo.gl/g9ogRvROvvOqJsrw1](https://photos.app.goo.gl/g9ogRvROvvOqJsrw1) I guess I’ll ask #Pimoroni for a replacement.

The soldering of the GPIO header isn’t the best. The speaker phat pinout is here, > **[Speaker pHAT at Raspberry Pi GPIO Pinout](https://pinout.xyz/pinout/speaker_phat#)** > > An I2S digital speaker and VU meter You may want to redo those pins.

I have the pHat Beat and run mine as a Pirate Radio (VLC radio).
