I also had sound cutting out in my Lucid. I realized that whatever sound was playing from the car speakers would cut out when I would pick up my iPhone. Once my phone lit up (still locked), the sound would cut out, but the music continued to play (I could see the timer still going). While it was annoying, I disconnected CarPlay and that solved the issue insofar as holding my phone doesn't cause the sound to cut out. It appears to be the car reacting to the phone becoming active and prioritizing the phone as an output. I don't recall this being an issue a month ago.
