White noise on Topping NX4 DSD in native DSD mode

[mmrv]

My Topping NX4 used to work perfectly in Native DSD mode until recently, now it only works in DSD to PCM mode playing DSD files. In native DSD mode, all I can hear is quite loud white noise, no error displayed or anything.  I can tell if the device is in DSD by a red LED on the device, while not in DSD the same LED is blue.

I am wondering what's changed? Can I downgrade the player a few versions back? I did not notice after which upgrade this started happening.

Regards,
Michael

Please set the hardware volume control in the app to maximum volume.

I changed bitrate to fix that on mine...
