I'm here to help fix volume issues in watching training videos in QuickBooks, @thabani-maposa-m.
When watching a video tutorial through the QBO website or YouTube, click the volume icon on the lower left side to make sure it's not on mute. Additionally, check your device to see if the volume is turned on.
If the issue persists, I suggest performing some troubleshooting steps to fix this. There are times that the browser is full of frequently accessed page resources, which causes some errors or unusual responses. Let's start accessing your account using a different or a private browser. You can use either of these shortcut keys:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Microsoft Edge: Ctrl + Shift + P
Safari: Command + Shift + N
Once you have successfully hear the sound, go back to your regular browser and clear its cache. This is done to speed up the process next time you do a transaction in QuickBooks Online. Also, an alternative way is to use other compatible browsers.
Meanwhile, I'll be adding this great Community resource in case you've got other QuickBooks concerns such as setting up payments, managing your income and expenses, running reports, etc. Please refer to this article for more details: Community help articles.
