Hi @juanchax, welcome to the Community! I don’t have access to the Samsung Tab S8 to confirm, but this could simply be a compatibility issue with that specific device. Please see below for more info.
Having said that, here are some troubleshooting steps to try:
- Make sure you are running the latest Android OS and latest version of djay.
- Download and install the latest DDJ-400 firmware from Pioneer DJ.
- Verify Android Audio Settings:
a. Ensure USB Audio Routing is enabled:
b. Go to Settings > Developer Options > USB Audio Routing and turn it ON.
- Disconnect all cables and reboot your device.
- Connect the DDJ-400 to your tablet using a Powered USB hub so it’s not running off USB Bus power and the internal tablet battery. Once connected, ensure that your tablet is charging properly as well.
- Launch djay and go to Settings>Audio Devices and ensure the DDJ-400 is selected as the main audio device. Make sure Main Output is routed to the DDJ-400 ch1-2 and Pre-Cueing is routed to the DDJ-400 ch3-4.
- If this doesn’t help, I recommend trying a different USB cable and/or a different USB Hub.
Hi @Slak_Jaw, thanks for your reply. Find my answers inline below.
-
Make sure you are running the latest Android OS and latest version of djay. –
[CONFIRMED] Android is up-to-date (Samsung is always pushing updates), and I downloaded Djay 2 days before purchasing the subscription, so it’s up-to-date as well (unless it’s not up-to-date in Google Play).
-
Download and install the latest DDJ-400 firmware from Pioneer DJ.
[CONFIRMED] Running v1.03 (released 09/Mar/2021)
-
Verify Android Audio Settings:
a. Ensure USB Audio Routing is enabled: Go to Settings > Developer Options > USB Audio Routing and turn it ON.
[CONFIRMED] The Android Dev Options setting is “Disable USB Audio Routing” on Android 14, but no worries, I made sure that the disable toggle is OFF (as in, Android will automatically route audio output thru USB whenever USB audio is available)
-
Disconnect all cables and reboot your device. [DONE]
-
Connect the DDJ-400 to your tablet using a Powered USB hub so it’s not running off USB Bus power and the internal tablet battery. Once connected, ensure that your tablet is charging properly as well. [DONE]
-
Launch djay and go to Settings>Audio Devices and ensure the DDJ-400 is selected as the main audio device. Make sure Main Output is routed to the DDJ-400 ch1-2 and Pre-Cueing is routed to the DDJ-400 ch3-4.
[NEEDS REVIEW] There’s no Settings → Audio Devices configuration option in Djay Pro Android (screenshot attached). Please check your info and confirm.

If this doesn’t help, I recommend trying a different USB cable and/or a different USB Hub. [CONFIRMED] Using brand new USB cable adapter (w/charging port) to power both units + usb connection
–oh how I wish Djay was open source to contribute
Hi @juanchax, thanks for the details. Please try downloading Algoriddim djay 5.2.6 from the app store not djay 2.
hey @Slak_Jaw, that’s a days number, as in, I downloaded the Djay app two days before purchasing a subscription to Djay Pro
I downloaded Djay 2 days before purchasing the subscription
Ah okay! Sorry I misread that. I can’t think of anything else to suggest at this point, but I’ve passed this onto our engineering team to see if they have any recommendations. I’ll report back when I hear back.
hey @Slak_Jaw , thanks for taking the time to look into this.
I took the liberty of running a few tests to help identify possible root causes and filed a support request, sharing all the details. 
You’re welcome @juanchax. Thanks for the update!
