[openob-users] No Received Audio

Hi Guys I have recently built a new Open OB link using 2 x Raspberry Pi 2s on Rasbian Strech release. The transmitter is using an Audio Injector sound card and the receiver is using a PiFi DAC+ v2.0. I have had this hardware configuration working previously but I note that there may have been an update to the OpenOB package (OpenOB 4.0) Has anyone had success getting the latest version of Open OB working on Raspberry Pi or is there a means that I can install OpenOB v3.0 instead of v4.0 Regards Terry O'COnnor
