So I had a strange one much like what you are seeing.
I've got the same transmitter, both the transmitter and conductor are on a shelf in my garage about a foot apart with the extra cable wound up between the 2. I've had this same setup running since Friday without issue. I did have my conductor sitting on a spare etherdongle I use to test with.
So today I made a couple tweaks to some sequences. Grab the card to format/put all the sequences back on and since I'm not really testing anymore didn't think I needed to leave my spare etherdongle out there and removed that from the shelf and put the card back in. Tonight lights started up like normal, 10 mins later I walked by a window and noticed the lights were off. Took a peak at the conductor and it was sitting at waiting and next show was tomorrow. Odd. Did a manual play of the show it started up but the music was extremely slow meaning it was like 3 to 4 times slower than normal but the lights were still going at normal speed, it would only play the first sequence also.
So I tried a reformat start over with the card again and this time the show wouldn't even start. After unplugging everything I remembered this post. So I unplugged my audio cable from the conductor and what do you know the lights started. So I moved the audio cable from where it was (just let it hang not touching anything besides the connection points in the conductor and transmitter). Show would play, music was fine and it would play more than one sequence. Very carefully put the cable back up and all seems to be good now.
Very odd is all I can say. Side note I'm on 91.7. I knew I shouldn't have touched anything
