Hi Ali,
I understand you frustration. It could be difficult when things don't work the way it should be on a brand new computer. However; let's try to narrow down to see what is causing this issue and try to fix it.
Please assist me with the following information related to this issue:
- What is the make and model of the computer?
- Does this behavior occurs only while watching videos on Netflix or is it while trying to play any audio/video offline?
- Have you connected any external speakers to your computer?
This issue could be caused by cables that aren't connected properly, damaged drivers, incompatible drivers, sound settings, missing updates, and problems with your sound card.
- Make sure that there is no phones, radio near to your computer as the frequency of these devices could interfere causing disturbance.
- If you have connected speakers, make sure your speakers are correctly connected to your computer.
- Many computers have three or more jacks that connect to a sound card or sound processor, including a microphone jack, line-in jack, and line-out jack. Your speakers should be plugged in to the line-out jack. If you're not sure which jack this is, try plugging your speakers in to each of the jacks to see if any of them produce sound.
- In some cases, you can work around the problem by disabling optional speaker effects that are known as enhancements. If disabling speaker effects solves the problem, you might need to update your audio driver.
Please follow the methods mentioned below:
Method 1: Try disabling the Audio Enhancements from the speaker properties.
- Click on the speaker icon on the system tray on the taskbar from the Desktop Interface of the computer.
- Click on the link Mixer.
- It will open up a small window named Volume Mixer – Speakers.
- Under device, click on the Speakers icon to open the Speaker Properties window.
- Open the Enhancementstab.
- Disable all the audio enhancements by selecting the check box which says Disable all enhancements.
