ML10x No Sound from the unit

Hi!
I’ve read a couple of post on the forum about the ML10x with no sound but it didn’t help me.

Right now, I’m assembling my pedalboard and I want to test them one by one, I’ve begun with a bypass preset, Input tip to output tip… no sound.

There is no USB connected has I’ve read it could cause a problem, it’s powered from a 400mA PSU, I’ve uploaded the latest firmware today (dec 27, 2024).

Input and output are connected trough regular 1/4 mono jack.

Any tips would be appreciated, thanks and happy Hollidays!

It’s fine to connect it via USB, but just make sure it boots up with 9V and the 9V remains connected if you want the audio to work.

Can you share a pic of the ML10X LCD so I can see how you have your bypass preset set up?

Here’s my LCD on my bypass preset and a picture to confirm my In and Out 1/4 jack.

When booting, the last message I see on the LCD is unmuting… so I guess it’s unmute…
Cables are good btw.

Pascal

Seems ok - I’m assuming the yellow cable is connected to the Amplifier, and the black cable is connected to the instrument?

I know you said cables are good, but just to troubleshoot - removing the yellow cable from the ML10X Output and connecting it to your instrument gives you sound? Same for removing the black cable from the ML10X Input and connecting it to your amplifier?

By the way, the “latest firmware dated dec 27” is a beta firmware. The latest stable firmware can be found here: Release Firmware v1.1.2 · Morningstar-Engineering/ML10X · GitHub

Just to further troubleshoot it isn’t an issue with the input or output port on the ML10X,
can you try setting up a preset like this:


Then connect your instrument to Return A, and your amplifier to Send B. Do you get any signal like this?

Ok… I did that, still the same…
BUT
When I bang REALLY HARD the strings on my bass I hear some tiny clipping sound far far away…

I’m gonna send the 1.1.2 firmware into my ML10X, I’m at 1.2.0 right now.

Same thing with the 1.1.2 firmware, no sound and tiny clipping far away when I bang on my instrument…
Just to confirm preset here is a picture of my laptop…

And my cables connections…
Black is instrument, Yellow is out to my amp.

Thanks for troubleshooting this.
