Paul, thanks for your answer. Building the IIS to HDMI interface and connecting it to the Raspi isn’t such a great problem. But if the PWDII needs the MCKL, I’m out of the game. Because as mentioned initially it’s not provided by the Raspi.
By now I’m feeding the signal of the Raspi to the PWDII by using a S/PDIF converter from Audiophonics (like Hifiberry Digi). At least this is transformer decoupled. I like the Bridge, but unfortunatly it’s not playing gapless…
So if you can find out if the PWDII is able of generating the MCLK from the BCLK I would be grateful!
