I have not used my studio for a while and now find that my monitoring system dos not function correctly with Fireface UFX (v1.63) and TotalMix 1.61. No sound reaches the headphone monitoring system. I have been trying to get it working for two weeks without success. There have been no recent hardware changes to my system. I'm using Nuendo-12 on Windows-11. Are there some important software updates I need to install to get things going again? Your help will be much appreciated. Best regards, Chris Palmer.

Hi, I am currently using a MOTU 8A and I was considering obtaining another one to use via AVB, but I am wondering about RME, since I am also considering a custom PC. The MOTU has an internal 48 channel mixer, with 128 internal "computer channels", so does any RME device function in the same way, that is I do not need external I/O, I just need as large as is possible internal channel count, even using 44.1KHz @ 24bit. I only really need compression, since all of my sounds are VST based so is this possible in DSP, since I use UAD to mix and need transparent recording. Thank you for any replies.

Hi, guys! I want to dim the headphone output on the ARC USB. It seems this is not possible at the moment. Is there a quick workaround for this? Thank you!
