Can I make my recording permanent?

In our greeting cards, no. If you purchased our sound modules, yes.
You can make your recording permanent by cutting the record wires ONE AT A TIME. Cutting both wires at once may accidentally erase your recording.

Can I change the speaker on the modules to a larger one?

For our marketplaces, we do not make or support modifications to the items we sell.  However, if you have or know someone with basic electronics knowledge and skill, you can easily change the speaker with another (larger) 16ohm one.

Alternatively, you can connect the device to a powered amplified speaker.  However, note that you will need to use a high-to-low converter circuit (you can search for them on eBay – https://www.ebay.com/sch/i.html?_odkw=high-to-low&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR3.TRC1.A0.H0.Xhigh-to-low+converter.TRS0&_nkw=high-to-low+converter&_sacat=0)

Can I change to an external power source?

It is possible to attach your own 4.5 – 5v DC power source if you have or know someone that has basic electronics knowledge and skill. However please note that we cannot support any modifications should something go wrong.

With the module positioned so that the speaker is facing furthest from you and the PCB is closest to you, the top of the left-most battery holder is +5vDC while the button of the right-most battery holder is ground (-).

My sound module will not record or play and it appears to be defective. What should I do?

Please try the following and let us know the result: 

Make sure you remove the plastic tab from underneath the slider switch.

Make sure there is no obstruction between the slider switch metal contacts.  Clean off any debris if necessary.

While laying the module flat on a surface, press down on the slider switch (the metal piece) and gently rock it back and forth.  This will also help to remove any debris from between the metal contacts of the slider switch.

Wiggle each battery.  If that doesn’t work remove and reinstall the batteries.  It’s ok to pry off the hot glue if necessary.  Sometimes there’s debris under the batteries so removing and reinstalling will help to remove it.

If your module has a “chip” remove the chip and reinsert it.

If your module has a light sensor or push button that plugs into the module, please make sure it is plugged in all the way.

An error message pops up as “USB device open failed/Cannot start – Code 10” when I try to connect the module to my computer. What does it mean? (For USB/DIY modules)

Are you using Windows 8 or 10?  As mentioned in the listing and sound loader download page, some users have difficulties with certain Windows 8 and 10 machines (some work, some don’t). Are you able to try using a different computer?  If possible try using a Windows 7, Vista, XP machine as it should work perfectly fine on these.

If not due to an incompatibility issue as mentioned above, the only other cause is a faulty USB connection. Please make sure that the USB adapter or cable is securely plugged into both the PC and module. You can also try using another USB port on your PC. If you have another mini USB cable or adapter you can try to see if that fixes the problem. These units use standard mini USB cables/adapters which is common to many mobile devices such as MP3 players, digital cameras, photo frames, GPS systems, mobile phones, etc.

If you suspect the USB cable or adapter included with your order could be faulty, we can ship you another cable or adapter to try. Please let us know.

I get a “Write SPI flash error” or Sound loader freezes when writing (USB / DIY Modules). What is wrong and how can I fix it?

Your sampling Rate setting is set too high, or the sound file duration is too long.


Choose a lower sampling rate setting.

Cut the sound file shorter using sound editing software (eg.Audacity).

Many of our customers use “Audacity” which is free and can be downloaded at


You can also find resources on YouTube showing how to edit sound files.



Is there a way to make the volume louder? (For USB/DIY sound modules only)

On our sound modules, there is no volume control on the module itself, or in the sound loader software.  The only way to increase the volume is to amplify the sound file itself.

If your sound is too soft, you can use sound editing software to adjust your sound file. Many of our customers use “Audacity” which is free and can be downloaded at https://audacity.sourceforge.net

You can also find resources on YouTube showing how to edit sound files. 



After programming, module BEEPS when activated (USB / DIY Modules and tags, excluding soundBOX)

How to fix a USB/DIY module that BEEPS when activated.

Did the sound loader software say “write success” (at the bottom of the window)?  If not, please try programming again and ensure that the software says “write success” when finished.

Does the sound loader software say “Version:” at the bottom right of the download window? If not, then if you click on the red icon on the top-left of the sound loader window, then click “About LX Sound Loader…”, does it say “…Version 1.0”? For this module, you will need to be using Version  Please download and install the correct version of the sound loader software.  The download page can be found here https://bigdawgsgreetings.com/soundloader-download/)
