I have just setup a pi 3b+ with an AMP+ running picoreplayer. Everything is running great at lower volumes. When i turn up the volume to about 3/4 the sound starts dropping out. I can turn down the volume and then everything is back to normal. I am using a mean well power supply at 18V to power the pi/amp+. Any ideas on what could be the issue?

HiFiBerry team Is it an Amp+ or Amp2? I guess, it's an Amp2 as the Amp+ isn't compatible with the 3B+.
Best regards,

Mark Wedge Yes it is an Amp2. Sorry about the typos.

Tim Reece I've just noticed this as well. Any fix for it?
Raspberry Pi 3B+ with Amp2.

John Gordon Help! Same problem. Did you ever find a solution?

Tim Reece Hi John,
In my case it was user error/stupidity. I had connected both channels from the Amp to one speaker in an attempt to downmix stereo to mono. Surprised I didn’t blow up the Amp.
I ended up doing this with software instead. With the added bonus of being able to run two stereo/mono outputs from 1 Amp.
In testing I found that I needed to be on the latest Pi Raspbian distro and kernel and latest squeezelite version. Before that I was seeing issues with audio quality or no audio at all.
