Dell 5310 Audio Fix
There are some settings that may need to be adjusted. Take a look at this Idea Guide for steps to correct the issue.
Connect Your Devices.
You can use the DA300 adapter to connect a number of cords and peripherals to your laptop with one click.
Connect your Network Cable.
It's a good practice to connect your ethernet (network) cable to the DA300 so that you can get a direct connection to the Internet. In benchmark tests, speeds were between 2- and 3-times faster when hardwired than when connected wirelessly. An added bonus is that the device is one less device using up a space on the Wi-Fi network.
