Just bought a new laptop and came across strange audio problem while testing it out. The audio level for incoming Skype calling is low. All other sound through laptop speakers are fine. But if I connect a jam bluetooth speaker, the incoming ring lever becomes normal. Although the Bluetooth speaker is connected the sound is coming through the laptop speakers and the sound playback window shows the Jam Bluetooth as default speaker. Other than the Skype incoming ring all other playback sound comes through the jam bluetooth when connected.
If I turn off jam Bluetooth unit the Skype level drops as the default speaker become the Realteck default laptop device. Other than that music, video playback sound levels are fine.

Any ideas on where the setting would be for this, is it a Realtek , Skype or Win 10 problem!

Thanks Bob
