Does your IFi Zen Steam have Low Gain?

I assume you set the maximum volume at 100?  You can set the max volume, the start volume and the db per steps.

@ricevs yes I do have the max volume set at 100.  I didn’t see the start volume setting.  I’ll look into that setting.  That might be my issue.  I use the Roon setting and control my volume with my amp volume controls and don’t use the iFi ap.

If you are using roon, go through all the options and make sure you don't have a DSP option enabled and turned way down. for this streamer.  Roon saves different settings for each device.

@carlsbad  @ricevs thanks for your suggestions…I got it solved…it was an oversight in the iFi software.  I had the settings set at 100%  volume but didn’t realize you have to go into the actual play app and also set the volume to 100% even if you are using roon as your control app. Live and learn!

It's the glitchy software. I had that issue with USB digital out with non-iFi DACs. I had to go into the setting and manually adjust the output to !00% but it would often change next time around.

It seemed to work fine with the matching iFi DAC.

I ended up returning it.
