When I plug headphone jack, my MBP auto selects soundflower (2ch). When I alt click to select headphone again, it won't be selected. I'll have to select sound flower (64ch) first then select headphone to have it working. Also when I unplug the headphones, I'll have to do the same thing to have the builtin speakers working again. It happened after I installed Parallel Access. I don't know if it was causing the issue, I installed it but I still suffer. I'm running Yosemite PB1. Any ideas how to fix this issue?
