Hi, and thank you for asking your question.
What's the make and model of your computer, please?
May I set up a quick remote session now, which will allow me to connect directly to your screen and assist you with reinstalling the audio driver?
Please reply back to me below. Thank you.
OK; let's get started with the remote session now, so that I can check the driver issue here. Please open up the following link:
Click 'I agree', then download the remote tool when prompted. An 'Elsinore Screen Connect' file will be downloaded by your browser (at the very bottom.)
OPEN/RUN the file from your downloads, and I'll be connected.
If you face any issues, just reply back to me below.
If you are having any issues with downloading/running the remote file as requested above, please make sure to reply back to me below. Thank you.
