Though, as you say, you do need the AudioServerPlugIn_MachServices key in your you install Microsoft Windows on your Mac, Boot Camp Assistant automatically opens the Boot Camp installer, which installs the latest Windows support software (drivers). It also seems to all work fine whether the plugin is signed or not. I ended up having to use XPC, unfortunately, but I tried CFMessagePort first and it worked fine.

Usb audio hal plugin driver for mac code#

(The code for my service and plugin is in that repo as well, in case that's helpful.) Note that without the UserName/ GroupName keys your daemon will run as root. This is what I ended up with: .plist.template. Then register it: # launchctl bootstrap system /Library/LaunchDaemons/.plist In it, set the MachServices key and add the name of your service: MachServices Set its owner to root:wheel and make it only writable by the owner. To make one, create a ist for your service in /Library/LaunchDaemons. And I think it means that your Mach service needs to be created by a launchd daemon. With that running, try to connect from your plugin again.įrom Table 2 in the Daemonomicon, you can see that only launchd daemons use the global bootstrap namespace. # launchctl bsexec $(pgrep coreaudiod) your_service_executable You'll probably need to have rootless disabled. You can use launchctl to test this by having it run the program that registers your service, but with the same bootstrap namespace as coreaudiod. And since 'processes using the global namespace can only see services in the global namespace' my plugin couldn't see my service. And the ones I had created worked normally from a regular process.Įventually I read the Daemonomicon and figured out that coreaudiod (which hosts the HAL plugins) was using the global bootstrap namespace, but my service was being registered in the per-user bootstrap namespace. I could look up and use every Mach service I tried, except for the ones I had created. I'm pretty sure I was running into the same problems in my AudioServerPlugIn. (same thing happened when I was trying the xpc_service approach) I noticed that when I use the debug mode with coreaudiod it does successful get the object reference of the mach service. I did get a console message regarding this.Ĭom.: The plug-in named SimpleAudioPlugIn.driver requires extending the sandbox for the mach service named This is my server side: CFStringRef port_name = CFSTR('') ĬFMessagePortRef port = CFMessagePortCreateLocal(kCFAllocatorDefault, port_name, &callback, NULL, NULL) ĬFMessagePortCreateRunLoopSource(nil, port, 0) ĬFRunLoopAddSource(CFRunLoopGetCurrent(), I tried this in a different app and it works just fine. However, in my audio hal plug-in (client side) I haveĬFStringRef port_name = CFSTR('') ĬFMessagePortRef port = CFMessagePortCreateRemote(kCFAllocatorDefault, port_name) now there is no sandboxd: () coreaudiod(552) deny mach-lookup / register message in console. Having that said, with the AudioServerPlugIn_MachServices attribute in the plist. I should be creating a remote port instead of a local in the audio plug-in. I am not sure if MesssagePort mechanism works anymore under sandbox. Is there anything else I need to do to make this work (like adding entitlements, code-sign) or this is not the correct approach.? I did some googlging and came to this articleĪbout adding AudioServerPlugIn_MachServices in plist but still no success. Sandboxd: () coreaudiod(2597) deny mach-register However, I got the following error in console trying to create port CFMessagePortCreateLocal. In the plug-in implementation, I plan to obtain audio data from another process i.e. I'm working on a coreaudio user-space hal plugin based on the exampleĭ/library/mac/samplecode/AudioDriverExamples/Introduction/Intro.html
