CoreAudio: Audio Output Device Stopped Error since macOS 15
Hello! I used the Apple CA Playthrough example code that pipes audio between devices. It uses AudioUnit callbacks to pipe the input to an output device, and I created a system equalizer with it - however users reported it stopped working in macOS 15. I am getting the error HALPlugIn.cpp:552 HALPlugIn::DeviceGetCurrentTime: got an error from the plug-in routine, Error: 1937010544 (stop) for the output device and no sound coming out of the speakers. The error only occurs when using a virtual device as an input, not using the microphone. First I thought the problem was in the loopback driver, but it also does not work with other loopback drivers like Blackhole. STEPS TO REPRODUCE Install a virtual device, for example "brew install blackhole-2ch" and run the CAPlayThrough example code (you need to add Mic Permission in the info.plist). Then set your system audio output to the virtual device, select the device as input in CAPlayThrough and hit start. You should see the error in console. My question: What did change in macOS 15 that could cause this? Is it something with the new permission handling maybe?

Question on Developer Membership?
I am about to buy the yearly membership. My good friend was going to work on a project with me. If I start the project with the membership, would he need to also have a membership to collaborate on the project together? Really just seeing if we need two memberships to get started or just one.

iPad IOS 18.3 Beta 2 Disables All Audio
With the installation of IPad IOS 18.3 Beta 1 a few weeks ago all audio on my iPad has been disabled. This includes internal speakers and all external devices from Bluetooth and Airplay. Today I installed a much anticipated 18.3 Beta 2 update hoping that the issues would be resolved as I had been following multiple posts about the audios issue on this site along with site as Reddit. Still no audio. I don‘t understand how the developers rolled out with this update knowing that the biggest fix needed to be the audio. I honestly don’t see how 18.3 Beta 1 even made it out of the sandbox without someone discovering this issue.

We have been unable to use ActiveSync email in our mail app since the IOS 18.2 update. We have repeatedly recreated the account but cannot improve the situation. We have normal access to ActiveSync mail on IOS 18.1.1 and ipadOS 18.2. Is there any additional configuration required in IOS?

Alarms- watch face widget no longer working properly.
Hello, since an update in September, the alarm widget on the watch face no longer counts down accurately like it used to. This is extremely frustrating for me because I used it for work so I have know exactly how much time I had in a particular circumstance. So for example, say I have an alarm set for 12:30. Before the update in September, I was able to look at my watch and know immediately that I had 24 minutes before the alarm, or look again and know it was the. 10 minutes before the alarm. Now, if I look at the watch face, it will say I have 24 minutes before the alarm, but it may actually only be 10 minutes before the alarm. I understand for some people this may be trivial, but it is really disappointing for me, and renders one of the most useful features of the Apple Watch useless to me now. I am hoping this is just an oversight during an update, so looking to see if this is something that is currently being worked on? I just installed beta 11.3 and still having the same issue. Now, if I press and hold on the watch face, like I’m going to change watch faces, then click out of it. It does update it. But it is not the same as it used to be. Thank you

Apple Music glitch
I have 2017 GMC Sierra and no bluetooth so I have to use USB. It worked fine for years but as soon as I down loaded the iOS 18 update when I try to listen to music, it plays a small clip of the song then stops and forwards through the rest of the song and skips to the next. It does this with every song whether it’s a playlist or downloaded on to my phone. I hate listening to the radio and having to listen to commercials which is why I have a 1 year subscription to Apple Music. Because of this glitch I have to listen to the friggin radio in the truck and search for the radio stations I like and suffer through stupid commercials every 10 minutes. None of the updates have fixed this glitch. Please, I beg you, fix it.

Using Swift-Protobuf to extract data
Hi! So I am not really sure how all this works. I want to use realtime data from the trains and buses in Sweden. This is their page: https://www.trafiklab.se/api/ As I understand it I should use GTFS data which come in Protobuf format. I think I must convert the Protobuf-data to Swift code. Not sure if this involves json. One file I have has the extension .pb. I tried to use this page: https://medium.com/@andy.nguyen.1993/protobuf-in-swift-809658ecdb22 When I write this: $ git checkout tags/1.1.1 $ swift build -c release -Xswiftc -static-stdlib I get this error: "error: 'swift-protobuf': the Swift tools version specification is possibly missing a version specifier; consider using '// swift-tools-version: 6.0.3' to specify the current Swift toolchain version as the lowest Swift version supported by the project" As you understand I am really not sure what I'm doing. Maybe there is a better way? Any help would be highly appreciated.

Screen time
My screen time report says that I’m on Google an average of 24 hrs and 4 minutes a day. How is this possible? I can’t be on Google more than 10 minutes a day let alone 24 hrs. I think it’s probably tracking whatever Google does when I’m not in the app or on the cite as part of screen time, but I can’t get it to stop. Are other people having this issue? How do I stop this so I can see my real screen time?

iOS 18 - Mail IMAP Issue
Hello everyone, Since iOS 18, there has been an issue where it’s not possible to set up custom IMAP accounts using one’s own domain. However, IMAP accounts from providers like Strato or other hosting services work without any problems. When will Apple finally resolve this issue? Is there already a solution for the problem? Disabling "Tracking IP" under Wi-Fi Settings doesn’t help. Uninstalling and reinstalling the Mail app also doesn’t resolve the issue. Thank you for your help. It would be nice if someone from Apple could comment on this matter. Thank you very much!
