Sparky looses the USBridge and awful sound

Hi i think my USBridge seems to have developed a fault. its started to drop off the system from time to to time. Today all of sudden started to miss samples, there was lots of digital noise and it was unlistenable. I rebooted and then the card is no longer visible in the os dietpi. Rebooted again and its now back but his has me worried the unit might be faulty. Its only six months old at best. What can be done here. I bought it from modmypi in the UK?

Spoke the ModMyPi who I bought the unit from. They spoke to Allo and are sending out a replacement board. Hopefully this sorts it out for good.
