2015 Tahoe Wired Headphone "design" issue

[bwesel]

2015 Tahoe LTZ. I have been having issues using wired headphones with the entertainment system. (my 4yo daughter insists on using her princess headphones instead of the wireless). Sometimes they work, sometimes they dont.

After many frustrated trips with the kids, I finally figured out that it had something to do with the screen being up or down when the vehicle was started. Took it to the dealer and they were able to reproduce the issue. They worked with their contacts at GM and after a couple of days and program updates, GM told them that the system is working as designed.

Dealer/GM is telling me if I want the wired headphones to work, the screen needs to be up and the headphones need to be unplugged when the vehicle is started. Has anyone had to stop at a rest stop or for gas while on a road trip when the entertainment system is being used? This does not seem like a logical design or a logical workaround.

Has anyone experienced this issue or been told this story from their dealer?
