I tried using this PowerShell command inside a PowerShell script to open the page to set the microphone.
[system.Diagnostics.Process]::Start("chrome","chrome://settings/content/microphone")
Unfortunately, this command simply opens the Chrome home page without showing the microphone setting page. Then after you have to write chrome://settings/content/microphone in the URL to reach the microphone setting page.
This facilitation is needed to make it easier for people that use webcaptioner (a free subtitling tool) to set the microphone. Most of them are deaf pupils. and deaf students with poor knowledge of PC settings.
Thanks in advance.
