Windows is notorious for shutting off devices when rebooting and then powering them back on after rebooting. This is particularly problematic with Network cards but as your question illustrates it happens with sound cards as well.

From this Dell forum other users suffer the same fate. As stated you you can:

You can save time by suspending and resuming your Ubuntu 16.04 as one of the answer in this thread describes.

Summary

You can’t reboot Windows and select Ubuntu from Grub menu. You have to shutdown and hit power button as per the links above. You could visit the Dell links and post a request for a Linux utility to power on the device.

The best solution may be to post a Windows question in Super User asking how to change Windows not to power off sound card during reboot.
