I have what looks to be like a potentially serious problem on a Dell T7600 that is configured with Windows 8.1. I have the speakers set up with a bluetooth USB adapter and a bluetooth speaker. Last week that speaker stopped working, so I have no local sound. On a lark, I decided to connect to the affected computer from Chrome Remote Desktop, and what is immediately clear is that the sound driver is playing continuously in a loop and never stops.
I tried this sequence:
1) Reboot computer
2) Connect to computer from Chrome Remote Desktop. So far there is no sound.
3) Login. So far there is no sound.
4) Start an application ( a stock price monitor ) that triggers multiple alarms, each with an associated sound.
5) Immediately after the first sound plays, the sound driver gets stuck in a loop and never stops.
The Windows System eventviewer is NOT loaded with messages. I cannot find any error that corresponds to the looping sound driver.
How should I go about diagnosing this and fixing it?
