obviously there's a problem with the DC Blocking Filter for the ADAU1452 in the latest revision 3.10.4.
If I only use one single DC Blocking filter for one channel in a project, everything's fine.
As soon as I add an algorithm to the existing DC Blocker or use a second DC Blocker somewhere else I get an error message when compiling the project:
"Variable 'sig_in_zm1' is already defined in this scope, previous definition at line 628 (650,0)"
This only seem to affect the ADAU1452 - I tried it in combination with ADAU1701 and ADAU144x and here's no problem at all.
Can you check this?
