Question No Audio Output device is installed

[Stefan Mtrovic]

I had just changed the display on my Acer E5-575G laptop and i noticed that my fps start dropping in FIFA 19 after 30-45 in-game minutes.When i open task manager system interupts are at 100% for a second and then drop to 4-7%.So i tried looking into it and i used the windows performance recorder while playing(recording CPU).In the DPC/ISR section i saw HDAudBus.sys using 10.08 of the CPU.
The way i tried fixing it is in the regestry,i changed the start parameter for HDAudBus from 3 to 4.While that didn't fix the problem(the fps drop is caused by overheating,i don't get any fps drop when i put my laptop with the display on the bottom with free space on the bottom).But the problem i have now is that my audio is not working(like i mentioned in the title).It didn't occur after changing it,but overnight,when i woke up my audio wasn't working.I don't know if what caused it was changing the parameter from 3 to 4(also there's no high CPU usage by HDAudBus so at least that's gone)or me updating Windows to 1809.Can someone help me?

I had a similar problem with audio drivers. The same thing, while playing at one point, the FPS fell to 10 -15 fps and in Task Manager the CPU was at 100%. I managed to solve it so I just went to the folder where that driver is located and delete it. I think it's a driver so try that
