So, I bought a Helm Bolt DAC and I also set up a RPI 4 streamer for use with Tidal HiFi. Everything is only days old.
Image was verified with a checksum and I’m assuming it flashed okay.
The problem is the volume is stuck - I can’t control it with either my iPhone, or thru myvolumino/Google chrome interface.
Originally I thought it was the DAC, but I plugged in a Soundblaster3 Play DAC and the volume works fine.
