Tsunami Super WAV Trigger player - corrupting sound files on SD card - help

Hello,

We tried using a Tsunami Super WAV Trigger player to play some soundscapes in an exhibit at a museum. I’ve tried two different players now and both of them have had this issue eventually.

The player is playing 3 different sound files into 3 different headphone jack outputs, and is set to loop them constantly. The power is turned off at the end of the day, then turned on the next morning every day.

The issue we’ve been having is that after a few days of running it corrupts the audio files themselves to the point where the speakers are either playing a fuzzy distorted version, or just playing an obnoxious loud noise instead of the files.

I’ve confirmed that it is the player and not the amp or speakers that are having the issue. The files themselves play the obnoxious noise once corrupted. I am using SanDisk Ultra Class 10 micro SD cards and have tried a few different ones, formatting in between.

The files are in this google drive folder if it’d help to take a look at the .ini and .wav files - https://drive.google.com/drive/folders/ … sp=sharing

An image of the setup is also in that folder titled “Tsunami Setup” (didn’t work to upload it here). It shows 4 outputs but we ended up just using the first 3.

Thanks,

Rachel

Hi Rachel,

Is this the same issue you were discussing with Jamie, aka robertsonics, in [this topic? If so, can you please provide the information he requested in his final response there? Specifically, have you tried different power supplies or isolating your power to the Tsunami? It sounds like the issue may be due to a noisy electrical environment or voltage spikes on power-up/power-down.

Since the issue has followed two Tsunami WAV Triggers, my guess is it is power-related and not something wrong with the boards/firmware. Also, to get a bit more information, when you are reflashing the SD Cards, are you fully formatting them using a tool like [this to completely wipe the card? The built in formatting tools from Windows and other operating systems sometimes do not fully wipe the card and that may be causing problems as well.](SD Memory Card Formatter for Windows/Mac | SD Association)](Tsunami Super WAV Trigger - Strange Sound Issues - SparkFun Electronics Forum)

Hello TS-Mark,

Yes it is the same issue as that other post - I forgot I posted that since its been so long.

I did use the same power supply when I switched the Tsunami boards… I could try a new one.

I did not use that special formatting tool, although I have switched the SD card to other un-corrupted SD cards.

The power supply I am using has Input: 100-240Vac

Output: 5Vdc/2000mA

Model SFE-5v2AU

I have the Tsunami player plugged into a power conditioner. The amps are also plugged into the power conditioner.

We want them all to turn on and off at the same time.

I would recommend trying a different power supply or powering the Tsunami directly through the Power Input pins. Just one note about those is in an extended use scenario like the project you have built, keeping the input on those pins closer to 5V is recommended since the voltage regulator can heat up a bit and is more taxing on the regulator if you are feeding it a higher voltage like 12V.

If you still are having issues with your audio files being corrupted after changing power supplies, let us know and we can troubleshoot further.

Thanks, I switched the power supply to a different power supply (but same model) . Will let you know if the files continue to get corrupted.
