Laptop speakers stop working when laptop undocked

[PaBaX]

I have an issue that I can't find described elsewhere. When I start my laptop sound works fine, when the laptop is in the docking station audio is routed through the docking station or I can play via internal speakers. When I remove the laptop from the dock (I usually do this by sleeping the laptop first) the internal speakers no longer work. I have been through all the troubleshooting steps but no issues are found or apparent, it's just that no sound is heard through internal speakers. If I plug in headphones sound plays fine through headphones, when I unplug I get a notification that the jack has been unplugged but still no sound from speakers. When plugged back into the docking station all is well and internal speakers work again. The only fix I have found is to restart the PC when disconnected from the dock, but that only works until the laptop is next undocked.

Elsewhere I have seen mention of the SRS control settings but I cannot find that application/settings. The sound is Realtek High Definition.

I did not always have this issue, it has developed in the last 6 months or so, I have had the laptop for about 2 years.
