To enable USB audio on your iPhone, you can follow these steps:
1. Unlock your iPhone and go to the Settings app. It typically has an icon that looks like gears.
2. Scroll down and tap on “Face ID & Passcode” or “Touch ID & Passcode,” depending on your iPhone model and settings. You may need to enter your passcode or use your fingerprint/Face ID to proceed.
3. Look for the “Allow Access When Locked” section and tap on it.
4. In the “Allow Access When Locked” section, you will find a list of options. Look for “Accessories” and make sure it is turned on. If it is already turned on, you can skip to the next step.
5. If the “Accessories” option is turned off, tap on the toggle switch next to it to enable it. This will allow your iPhone to connect to accessories even when it is locked.
6. Once you have enabled the “Accessories” setting, you can connect your USB audio device to your iPhone using a compatible USB cable or adapter.
7. Your iPhone should recognize the USB audio device and automatically switch the audio output to it. If it doesn’t, you may need to go to the Control Center by swiping down from the top right corner of the screen (or from the bottom on older models) and tap on the audio output icon. From there, you can select your USB audio device as the audio output.
It’s worth noting that not all USB audio devices may be compatible with iPhones, so make sure your device is specifically designed to work with iOS devices. Additionally, some USB audio devices may require additional software or apps to be installed on your iPhone for full functionality.
I hope this helps you enable USB audio on your iPhone!
