Burned up my Pisound?

kleag · October 21, 2025, 8:42pm

Hi,
I fear that I have maybe broken something on my Pisound. I’m building a guitar multieffect with a raspberry pi 5 (with pipewire and wayland). I just finished soldering all the components and made several tests of them connected to the extension headers of the pisound. Unfortunately, when I plugged again my guitar and my amp, I did not hear any sound at all. I first checked the two cables and they work.

Then I checked the devices and everything seems OK (devices appear on qpwgraph and aplay etc. give the correct output).

I also checked the volume and mute/unmute widgets on the RaspberrypiOS desktop and they are OK.

I also removed everything other than the pisound and plugged it in directly on the pi. No change.

I tried it also on a raspberry pi 4 I have and got the same results.

I share a photo of the rp4 with the pisound on it and a view of qpwgraph with the devices.

Do you think I could have broken something that prevent only input and/or output from the jacks? What could I do to verify? I have only a multimeter to test the electronics. Do you think of other things at the software level that could prevent the signal to be sent to the amp?

Best,

Gaël

Try running this command to test audio output first:

speaker-test -c2 -r48000 -Dhw:pisound

It should be producing white noise on the left channel, then on the right one.

Could you also post a picture of the bottom side of Pisound? If there are wires obstructing the view, try to make a couple of pictures so I can visually inspect the surrounding components.

Hi Giedrus,
Thanks for you answer. I got no sound with the speaker-test, but an input/output error. See the snapshot.
I join also photos of the bottom side. I hope they are good enough.
I am absolutly shameful of my soldering skills…

Could you also attach the dmesg log after having run the speaker-test?

Do dmesg > dmesg.log and it will write it to a dmesg.log in your current directory (usually your home directory).

Don’t worry about it, practice helps Make sure you heat up both, the pad/ring and the pin - the solder flows to the heated parts. Apply solder at around the place where the soldering iron and the other surfaces meet, even better, if it’s possible to not apply it to the soldering iron directly, but on the opposite side of the pin/pad. If solder won’t stick - some flux may be needed, but the solder core usually has it in its internal structure, so most of the time it’s enough to apply the solder wire at the correct location. Additionally, some contacts that connect to a polygon, most usually the Ground plane, require much more heating up time, before the solder flows nicely. The rectangular pin on the header is a Ground pin, so heat it up for a bit more time.

You do have some excess solder on your pins, it would be good to reflow them and remove the excess with a solder wick. The shape of solder to aim for is a cone.

I notice some scratches on the bottom side on the trace along the edge of the board, it may have broken or impacted contact. Please check whether these pins are connected, and measure the resistance:

Thanks for your encouragements on the soldering side. I will try to correct as you suggested.
I put below the dmesg output. For the resistance between the indicated locations, there is continuity and a resistance of approximatively 14.8Mohm.

Ok, this seems to be problematic - the resistance should be close to zero, < 0.3 Ohm. Just to confirm, you measured it while Pisound is unpowered? Also double check whether the contacts measured are exactly as marked on the picture.

If it’s indeed very high resistance, these marked areas might be the cause of this. The trace damage can be repaired by carefully scraping off the green solder mask at the impacted area, and building a thin layer of solder bridge, using a bare wire if necessary, in case the distance is too big to make it with solder alone, restoring the connection.

See this video for the process:

I measured again at the same place. Here:

But surprisingly, this time I found the expected resistance of 0.3Ohms…

Here are some detailed photos of the scratches you noticed:

Is it still interesting to rebuild the traces, even if the resistance is OK? The surface is clearly scratched as I measured a continuity between the two scratches, showing that the copper is exposed, at least. I’m conscient that the trace itself can be broken, or not.

The video is very clear. Thanks.

Yeah, sometimes some thin layer of flux or oxidation inhibits proper measurements, in that case, slight scratching up of the surface or more force helps measure accurately.

In that case, the scratches don’t seem to be the problem.

I don’t visually see any other issues. Please try cleaning up the soldered pins, just in case they are making contact with something they shouldn’t be contacting with.

kleag · October 29, 2025, 5:28pm

Hi, I cleaned the pins:

It’s not perfect. I should improve the connections, but at leas I think we can exclude unvisible shorts.

Unfortunately, this is still the same: drivers see the pisound. It is selected as source and sink in wireplumber with volumes at 1.0. But there is still input/output errors on arecord and on speaker-test.

Giedrius · October 30, 2025, 7:23am

The pins now look much better, good improvement!

After you run speaker-test, do any new messages appear in the dmesg log?

kleag · October 30, 2025, 8:52am

Here are the messages that appear on running speaker-test:

dm2chan4 failed to stop
dm2chan4 is non-idle!

Giedrius · October 30, 2025, 9:24am

These appear in the dmesg log? Could you post the entire contents?

kleag · October 30, 2025, 11:01am

Yes, I ran dmesg -w and these line appeard during the execution of speaker-test.

Here is the full log:

Hi, just a little ping in case this has slept out of your view .
I start to wonder if I should buy a second pisound
Or is there possibilities to send my current one back for repair?

Giedrius · November 7, 2025, 1:06pm

Indeed, it slipped my view. I suspect this line might appear due to PCM FS or PCM CLK pin connectivity issues, but as hard as I looked into your photos, I couldn’t find any troubling spots.

We could look into repairing your Pisound, please send us an email with your details.
