Lenovo Ideapad 520 (USB 2.0 output/Windows10)
Topping DX3 pro (USB input)
ASIO audio drivers
Topping USB drivers
Foobar2000 with foo_input_SACD component installed
I’ve been using Equalizer APO/Peace for some weeks now. I really like the results. It worked absolutely fine … until I noticed that I only got 16bit/48Khz output trough my USB connection to my Topping DX3 pro DAC/amp.
I don’t have that many high-res audio files, so it took some time to notice it.
To fix it I installed the Topping drivers and followed the instructions included in the setup documentation found on the official Topping website. These instructions include the installation of ASIO drivers to enable DSD playback using foobar2000 (which is my favorite audio player anyway).
All works fine. I can send high-res PCM and DSD over USB to the Topping now. Playback happens without issues… except for Equalizer APO. It looks like the app is completely bypassed.
I checked to see if all devices are enabled. When playing high-res PCM files I can see the topping in the device list. (clicking"C" next to the evice selection dropdown box) Selecting it has no effect. When playing back DSD, the Topping doesn’t even show up in the device list.
Looking at the “peak value meter” at the bottom of the GUI (peace) it looks like the audio doesn’t even arrive at the app. There’s no signal.
Does anyone know how to fix this?
