Hi,
Anyone else with the XPS 15 9550 have problems with headphones / internal speakers not working correctly?
On booting the PC without any headphones, the speakers work. However headphones do not work if inserted. On removing the headphones, the speakers then cease to work.
However if booting the PC with headphones inserted, the headphones do work. On removing them, the speakers do not work. The headphones do not work if reinserted.
Both these scenarios are fixed by rebooting the PC.
Windows 10 and all drivers - including audio and BIOS - are up to date as of 17/11/5.
This issue seems similar to the one described in:

Does anyone else have the same problem?
