Troubleshooting/QA
1: How do I power on the K4 Mini stereo DAC?
• Besides the USB Type-C cable included in the package, you’ll
also need a 5V power adapter with USB output, such as your cell
phone’s charger or power bank.
Note: When you plug the USB Type-C cable to the K4 and hear the
“click” sound, that means the connection is up. Please do
not intend to insert the cable to K4’s USB/POWER port fully
which can cause damage.
2: Why is it that all my cables are plugged in well, but the
K4’s RCA analog output is still silent?
• Please check if the input mode selection is correct.
• The K4 supports 3.5mm headphone output and RCA sound
output simultaneously. You can check if the headphone output is
normal or not when you find the RCA output has no sound.
• Please try to replace the RCA cable and test again.
3: Why do I get endless white noise?
• Please check that your input device is using Dolby/DTS audio,
If so,please change it to RAW/PCM type and try again.
4: No Dolby/DTS audio and I still get noise through the
USB input?
• Please try to connect the USB Type-C cable to the other USB
ports on your PC. Some USB ports may have unstable data
transmission so please try to swap it;
• Please try again on another computer;
• Please replace the USB Type-C cable and retest;
• Select Start, then type device manager in the Search box, and
then select Device Manager;
5: The K4 is not recognized on Windows?
• Click Start menu, then type device manager in the Search
box and then select Device Manager;
• Expand Universal Serial Bus controllers. Press and hold (or
right-click) a device and select Uninstall. Repeat for each device;
• Once complete, restart your computer. Your USB controllers will
automatically install.
• If Windows update causes the device to be unrecognized, please
update all windows components and reboot and retest. Please
contact us if the problem still insists.
6: How to do plug-and-play on Windows?
• Just click the sound icon in your notification area;
• Click the “Select playback device” option;
• Select the playback device “Fosi Audio K4”.
7: I can't play Spotify music in Plug-and-Play mode?
• Please exit the Spotify app and switch the playback device to the
computer's own sound card device, open Spotify and play,
confirm that it works and then switch the playback device to
DAC-K4 “Fosi Audio K4”
8: How do I get the highest 24Bit/96kHz resolution on my
