HIFI module HD stopped working / is very noisy

FlorianFreitag

Hello,
we recently ordered a HIFI HD module and it was working great at first. After a couple of days it suddenly stopped working correctly. If it is connected to USB, there is random static / white noise playing over the speaker, if i try to play sounds, they are masked by strong white noise. The BPOD still recognizes the Module in the GUI and matlab does not show any errors when trying to start a protocol. I tried to update the HIFI software but that has not helped. I also noticed that the module got quite hot during testing. we did not change the code or any hardware connections between it working and not working. I am wondering whether this is fixable or we need to order a new one ?

Best,
Florian

Hello Florian,

We've haven't seen a failure where sounds play normally but are masked by white noise. Overheating is a bad sign.
Unfortunately my impression is that it will need to be replaced.
Please reach out to support@sanworks.io to set up the replacement shipment.

Thanks,

Josh
