I have an Inspiron 7506 2-in-1 that is less than a year old. For over a month now I've been experiencing delays in audio and video loading. For example, YouTube videos will buffer for about 20 seconds before starting or will simply display an error message ("If playback doesn't begin shortly, try restarting your device").

After testing on multiple browsers and websites, I've determined the Realtek Audio driver to be the problem. I'll list everything I've tried below:

1. Disable the driver. Videos load successfully without any buffering, but the laptop cannot play any audio.

2. Install Realtek Audio driver version 6.0.9098.1 (As suggested by 505Kelvin in this thread <https://www.dell.com/community/XPS/Restart-has-become-very-slow/m-p/8065635/highlight/true#M91840>). This fixed the issue for three days, but it has stopped working again since yesterday.

3. Install Realtek Audio driver version 6.0.9257.1 (As suggested by 
wiz101 in this thread <https://www.dell.com/community/XPS/XPS-15-9500-Realtek-driver-6-0-9210-1-static/m-p/8095658/highlight/true#M93058>). This did not work.

4. Install Realtek Audio driver version 6.0.9228.1. This did not work.

5. Install Microsoft High Definition Audio Device version 10.0.19041.264. This DID work, but the sound quality is worse.

Although it fixes the issue, the Microsoft driver isn't the ideal solution since it sacrifices sound quality. Is anyone else dealing with this issue, or does anyone have any ideas? I truly appreciate any help!
