Dietpi 6.8 no Audio Output

I have been using usbridge for almost a year with my Auralic Polaris (usb-dac) and Squeezelite. I control my system with iPeng. Dietpi v6.6 was installed in the headless version. After the update to 6.8, there was an issue. Usbridge has no sound output.
I reinstalled Dietpi with allo gui (version 6.6). Sound was back.
After an update to 6.8 again no sound output.
Does anyone know this behavior? What could be the reason?
Thank you

The solution in my case was to set the Alsa mixer to 100% each time.
Thank you


Apologies, this is a known issue with a recent Allo + Sparky patch, will be resolved in v6.9
