Hifiberry miniamp not working with pulse

I've gota Hifiberry miniamp cknnected to a Raspberry Pi3. I'm running Bob Rathbone's internet Radio code on the latest Raspberry Pi OS. When set to PulseAudio I receive the following error message through the 4x20 LCD display: Failed to enable output "Hifiberry DAC /Miniamp/Pimoroni pHat" (pulse); pa_context_connect() has failed: Connection refused Changing to Alsa has fixed the problem and the amp is working now. Is the Hifiberry miniamp compatible with PulseAudio? Are there any further steps I can take to test this? Here's my build blog for anyone interested: https://bmsdoug.wordpress.com/internet-radio/
