The problem is that foton does not inherit the model sample rate when launched from DTT/awggui. This is likely some shared/linked/dynamic library issue, the binaries we are running are precompiled presumably for some other OS. I've never gotten this to work since we changed to SL7 (but I did use it successfully in 2017 with the Ubuntu12 install).
do you really mean awggui cannot make shaped noise injections via its foton text box ? That has always worked for me in the past.
If this is broken I'm suspicious there's been some package installs to the shared dirs by someone.
