I'm not the guy who posted this in the main 12.0.179 thread, but I also have SoundBridges that won't connect to 179. The MC library shows up on the SoundBridges, but I get a "Connection to server failed" message when I try to connect. My setup is:
Two SoundBridges - an M1001 with 2.7.65 beta firmware, and an M2000 with the latest release firmware (2.5.174). Neither will connect.
The server settings that worked in 12.0.164 were: auto detect receiver, convert if necessary to MP3 (all my audio is MP3 anyway), and auto TCP port.
I have tried various combinations of server settings in 179. Convert (no/yes/if needed), receiver (auto/SoundBridge) and log file requests (yes/no). Probably not *every* permutation of those, but enough to be stumped. A few random advanced receiver options too for good measure.
If you have specific things for me to try or additional questions I'd be happy to help, but please try to ask soon. I'll keep 179 for a day or so, but then I'll revert to 164. The SoundBridges are too important.
