iphone – How you can setup a MAX Audio output degree for BlueTooth Headphones

Lengthy story quick, I purchased non-Apple branded headphones, the headphones have some code to auto transfer the quantity to about 75% each time I flip them on, slightly than the most likely ~10% I favor to have them at and switch the headphones off at.

Apple doesn’t present a max bluetooth quantity setting so far as I’ve researched.

I might like a easy code to maybe hook into default bluetooth dealing with, and make sure the quantity is at my most popular ~10% quantity when about to play.

I’ve posted on ios types asking for Apple so as to add a really SIMPLE setting of max bluetooth quantity, and I’ve seen many others on the Apple types have annoyingly tough instances with their bluetooth headsets being too loud on join. It appears Apple will not repair the issue, as it is not their branded bluetooth headset.

However, it is assaulting my ears each time I neglect to lower the quantity earlier than enjoying a video/music after connecting. I am hoping an ios savy individual is aware of a solution to hook into the bluetooth or playback begin, to make sure quantity is low sufficient (ideally readjusting it decrease) to be snug on playback begin.

It definitely would not be difficult code. Perhaps somebody savy with IOS is aware of a means? I’m a software program developer, however not usually for IOS stuff, however I ought to be capable to comply with any code you possibly can assist with.

ChatGPT gave me this response, which appears fallacious (relating to not with the ability to programmatically change the quantity) as my headphones are rising the quantity, so I believe I ought to be capable to programmatically lower them in one thing like this script and maybe right permissions (or, possibly the headphones are not rising the quantity and it is simply IOS dealing with my headphones in an inappropriate means – making the quantity means too loud – in order that I purchase their Apple branded merchandise?), ChatGPT mentioned:

To realize this performance in iOS, you’ll usually use CoreBluetooth framework to detect when Bluetooth is about for use and AVFoundation framework to regulate the quantity. Nevertheless, it is essential to notice that straight manipulating the quantity programmatically shouldn’t be potential on iOS resulting from privateness and safety restrictions imposed by Apple. Customers need to manually set the quantity on their gadgets.

Nevertheless, you possibly can alert the consumer or counsel decreasing the quantity programmatically when a Bluetooth machine connects. Here is a conceptual instance of the way you may implement this:

swift:

import UIKit
import CoreBluetooth

class ViewController: UIViewController {

    let bluetoothManager = CBCentralManager()

    override func viewDidLoad() {
        tremendous.viewDidLoad()
        // Do any extra setup after loading the view.
        bluetoothManager.delegate = self
    }
}

extension ViewController: CBCentralManagerDelegate {
    func centralManagerDidUpdateState(_ central: CBCentralManager) {
        if central.state == .poweredOn {
            // Scan for Bluetooth gadgets
            central.scanForPeripherals(withServices: nil, choices: nil)
        }
    }

    func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
        // Examine if the found peripheral is a Bluetooth machine you are serious about
        // For demonstration, to illustrate your Bluetooth machine has a selected title
        if peripheral.title == "YourBluetoothDeviceName" {
            // Alert the consumer or counsel decreasing the quantity
            let alertController = UIAlertController(title: "Bluetooth System Linked", message: "Please guarantee the quantity is low to your security.", preferredStyle: .alert)
            let okAction = UIAlertAction(title: "OK", type: .default, handler: nil)
            alertController.addAction(okAction)
            current(alertController, animated: true, completion: nil)
        }
    }
}

On this instance:

We’re making a CBCentralManager occasion to handle Bluetooth interactions.
In centralManagerDidUpdateState, we’re checking if Bluetooth is powered on after which initiating a scan for peripherals.
In didDiscover, we’re checking if the found peripheral matches the one you are serious about. In that case, we’re presenting an alert to the consumer, suggesting that they decrease the quantity for security causes.
Bear in mind, you can’t programmatically regulate the machine quantity straight resulting from iOS restrictions. You may solely immediate the consumer to take action.
