“Popping Sound”

Problem Description DP extended display: When hot-plugging the downstream DP port, there is no audio output. (Occurs randomly) 2. Setup Condition The product is connected to the following platform: Platform: Apple MacBook Pro (16-inch, M4 Max, 2024) The DP port is connected to the following monitor: 3. Reproduction Procedure Step 1: Connect the DP port to the extended display ASUS VP28U (4K 60Hz) Step 2: Connect the platform Apple MacBook Pro (16-inch, M4 Max, 2024) Step 3: Hot-plug the downstream DP port → no audio output (random occurrence) Bug Description DP extended display: When hot-plugging the downstream DP port, there is no audio output. (Random) Affected Platform & Monitor Combination Apple MacBook Pro (16-inch, M4 Max, 2024) & Samsung S32BG850NC (4K 240Hz) Vendor Anaysis: After analysis, we found that the issue also fails when the host is directly connected to the monitor (tested with two different USB-C to DP cables, both showing the same failure). The RTS5490 onl

Problem description: Connected to a Sharp 8TC60DWTX (8K) display, but unable to select 4K resolution Setup Condition Apple MacBook Pro 16-inch M4 Max Sharp 8TC60DWTX (8K) 3.Duplicate Procedure After connecting to 8K MNT and select 4K solution, it still display as 8K. Vendor analysis: 8K60 shows no image; switching to 30 Hz works normally → After analysis, we found that the 8K60 timing output from the MacBook is incorrect. The horizontal blanking (H-CBlanking) is too small to accommodate the audio data, so the RTD2191E does not output video to the monitor. → This issue does not occur on Windows platforms, confirming that this is a host-side issue.

Hello everyone, I am currently developing an app for my Swift Student Challenge submission that focuses on human motion analysis using the Vision framework. To effectively demonstrate the app's technical capabilities during the review process, I need to include a sample video showing a person performing specific movements. However, I want to ensure that my submission strictly adheres to all intellectual property guidelines. Instead of using existing copyrighted videos or public social media clips, I am considering using Generative AI to create an original, royalty-free sample video. This video would feature a character performing movements designed specifically to test my app's pose estimation and feedback logic. I have a few questions regarding this approach: Is it acceptable to use AI-generated sample assets (like video clips) to demonstrate technical features when it's difficult to record high-quality personal footage due to environmental constraints? If I clearly disclose the tools used and the reason for

Hello Apple Bluetooth team, We are developing a real-time call translation system that streams raw PCM audio over BLE between iPhone and custom earbuds. This works reliably on iPhone 14 / 15 / 16, but on iPhone 17 (Bluetooth 6, N1 chip) we see severe and repeatable BLE packet loss, affecting both microphone uplink and TTS downlink. Our audio stream 16 kHz, 16-bit mono PCM 20 ms frames (~640 bytes) continuous bidirectional BLE streaming What happens on iPhone 17 BLE packets are frequently dropped entire audio frames are missing results in ASR gaps and broken TTS playback occurs even with strong RSSI and no RF interference Same firmware, same BLE protocol, same MTU and connection interval work normally on older iPhones. Questions We would like to know: Did Bluetooth 6 / N1 change BLE throughput, buffering, or scheduling? Are there new limits on sustained notify / write-without-response traffic? Is BLE audio now arbitrated differently against Wi-Fi / A2DP on iPhone 17? Is BLE

Currently, we are developing an all-in-one DualSense utility for macOS. We are exploring how to integrate shortcuts into our app. Our vision is to have the user use the native Shortcuts app to choose the controller buttons that should trigger the shortcut action, such as opening Steam, turning on audio haptics, and more. As we explore this approach, we want to see whether we need to build the UI in our app to set the triggers or can we do this inside of Shortcuts? Can button presses recorded by our app trigger shortcuts? Can those button inputs be customized inside of Shortcuts or should we develop it into our app? And if we have it in our app, can our app see, select, and trigger shortcuts?

Hi, I have an app built in Unity that I am trying to sign an notarize for distribution. I can successfully codesign the app and it runs properly. But after successfully notarizing the app, the app stops opening. My process is as follows: # codesign the app. omitting --deep --option runtime or both will result in notarization failing codesign --force --deep --verify --verbose --option runtime --sign Developer ID Application: ORG NAME (ZZZZZZZZZ) path/to/app.app # create notarization submission zip /usr/bin/ditto -c -k --keepParent path/to/app.app path/to/app.zip # submit for notarization xcrun notarytool submit --wait path/to/app.zip -v --apple-id apple@id.com --password aaaa-aaaa-aaaa-aaaa --team-id ZZZZZZZZZ Notarization seems to succeed. Running: spctl -a -vvv -t install path/to/app.app -returns: path/to/app.app: accepted source=Notarized Developer ID origin=Developer ID Application: JOHN DOE (ZZZZZZZZZ) The Problem: Before code signature, the app runs normally After code signature, the app runs normally Af

Our application is designated to be used in a quite noisy environment (childcare facility) so we have implemented really annoying custom sounds. Unfortunately the system audio session playing custom sounds is apparently limited to half of the device volume possibility, even though the user sets full volume in the settings. How to change this behaviour to get louder notification sounds? To be clear, I don't want to overcome user settings. If the user sets quieter volume or he sets the silent mode, the application should be silent too. I just need that 100% volume settings is actually 100% device volume. This is a really critical feature for us and for our customers. We have already tried to ask for the critical alerts and we have been rejected.

We are trying to extend our app with Push To Talk functionality by integrating the Push To Talk framework. We are extensively testing what happens if the app is running in the foreground, in the background or not running at all. When the app is in the foreground, and the user has joined a channel we maintain an open connection to our server. When a remote participant starts streaming audio, we immediately call setActiveRemoteParticipant on our PTChannelManager instance. The PTT system will than call our delegate's channelManager:didActivate audioSession method and we can successfully play the incoming audio. When the app is not running at all, there is of course no active connection initially. When another participant starts talking we send a push notification. The PTT system will start our app in the background, call the incomingPushResult method on our delegate, after returning the remote participant the PTT framework will then call the channelmanager:didJoin delegate method which we will
