USB-C Sampling Not Working on MPC Live III After 3.9 Update

HI !

USB-C sampling worked fine on my MPC Live 3 with the previous firmware.

After installing update 3.9, USB-C sampling stopped working properly when connected to Samsung Android phones.

It still works correctly with my laptop and an old Samsung Galaxy S9, but with every newer phone I tested, the input becomes unstable. There's no usable audio—only strange digital noise that causes the input signal to peak.

I've tested around a dozen different phone models with the same result.

Has anyone else experienced this after updating to 3.9? Is there any known fix for this bug?

I've already tried resetting the MPC, but it didn't solve the problem. I also tried plugging the USB-C cable in both orientations, but that made no difference.

I'm using the same original USB-C cable that came with the MPC. It worked perfectly with both my phones and my laptop before updating to firmware 3.9.

Now USB-C sampling only works correctly with my laptop (as before) and with one old Samsung model (Galaxy S9). None of the newer Android phones work correctly.

This seems very strange.

Thanks!

Did you change you internal card settings frome 24in/24out to 8in/8out ?

No, didn't change it.
