In macOS Mojave, Apple has introduced some system-level privacy controls for your mic and camera. These are great for privacy, but it is possible that your browser was mistakenly blocked from accessing your devices. You can check on this and allow your browser to access them from the Security & Privacy section in your System Preferences. 

これらの設定にアクセスするには、次のようにします。

1. Click on the Apple in the top left > select System Preferences.
2. Click on the Security & Privacy section.
3. Click on Camera in the list of options, and tick the box next to your browser to allow access.
4. マイクロホンのために手順3を繰り返す
5. この後、ブラウザを再起動すると、アップデートが有効になります。

In Windows 10, you're able to set a default Microphone, but there are also system-level Camera permissions on what applications can access your camera. For either of these settings, the first thing to do is open up your system settings by clicking on the Start menu and selecting the Settings gear.

デフォルトのマイク

You can adjust the microphone settings by typing "Mic" into the search bar and going to the Sound settings. Scroll down to Input and use the dropdown to select the proper input device

カメラのアクセス権

Camera permissions can be accessed by typing "Cam" into the search bar. These settings are under your general Privacy settings, but a search is the easiest way to access them. From here, be sure that your browser has permission to access your camera.

マイクとカムのデフォルトは、Chromeでいくつかの方法でアクセスできますが、最も簡単なのは、以下のリンクをURLバーに貼り付けることです。

Cam:  chrome://settings/content/camera

Mic:  chrome://settings/content/microphone

From these areas, you can manage the default cam/mic for Chrome, and also whitelist or block websites from accessing your cam/mic! Be sure that SpatialChat ("https://spatial.chat:443) is listed under the Allow section.

In Firefox, you can also use a URL link to get to your privacy settings. Start by going to about:preferences#privacy, and then looking under the Permissions section. Here you can adjust which websites are allowed to use your camera, and you'll want to see SpatialChat listed as Allow.

To adjust which camera or microphone Firefox is accessing, you'll need to go into a SpatialChat space. From here, click on the icon that's just to the left of your URL bar, and you'll have a dropdown menu where you can select the camera you want to use.

マイクロソフトエッジ

Using Microsoft Edge, you have to go to edge://settings/profiles and then click on the "Cookies and site permissions" button. After that, scroll down to the Microphone and Camera settings. Here you can choose the default microphone and camera. Moreover, you can set site permissions, and the browser will use the site permissions you've set in Microsoft Edge regarding SpatialChat.

Cam: edge://settings/content/camera

Mic: edge://settings/content/microphone

If you delete a site from the Block list, it may happen that Edge will not request access to devices again in the browser. In this case, you need to add manually site access (https://spatial.chat:443) to the Allow list for both the camera and the microphone.

In Opera you can get to settings by typing " settings" into your URL bar. From here, click on Websites in the left hand menu list. Then scroll down to the Microphone and Camera area, and use the dropdown menus to select the default devices. You can also adjust your permissions preferences and set up Exceptions as necessary.

Cam:  opera://settings/content/camera

Mic:  opera://settings/content/microphone
