I hope someone is able to help, I purchased a DAC+ to use with my Raspberry Pi 3B+.
I want to use the OpenAuto Pro software.
The issue I'm having is I'm unable to control the volume from within the program. Goes back to 0 any time I try and change it.
When I go back to the Raspbian OS, and click on the volume control I see the following error message.
Connection to PulseAudio failed
When I contacted the OpenAuto creators, they said it's an issue with the HiFi Berry and not their software.
I'm hoping someone is able to help me get this all working correctly, as I'm totally stuck on what to do.
