mttrb / antipopd Goto Github PK

I wonder if this is Hardware issue, logic board, busted amp, speaker...
I refuse to believe this happens on every Mac.

Any insights?

I've MacBook Pro 2017 TB, pops after playing brief sounds like notifications.

Hey! This is my first issue post in a long time, so I apologize if I'm leaving anything out that is glaringly obvious. I will be happy to amend this issue with necessary information.

The issue that I'm seeing is that after building with the given instructions, the program gives a segmentation fault code related to bad access.

The computer I am using this on is a PC running Mac OS, and so if this runs on High Sierra on real Macs, then there is clearly not a real issue here. The world of debugging unofficial Mac issues is surely a nightmare, and no one could be blamed for not wanting to investigate further.

Included is a terminal log where I:

• Build with debugging symbols
• Open antipopd in lldb
• Set a breakpoint at the exact line that causes the crash
• Print the value being passed into the function 'CFGetTypeID( )'
• Take one step in lldb, which displays the crash
• Exit lldb. Run antipopd as a normal user, and as root, which both result in a segmentation fault

Thank you for reading this issue, take care

Hi Matthew,
Thanks very much for writing this. Should I be able to see a process called "antipopd" running in Activity Monitor? I don't see any such process executing but the sound popping appears to be fixed. I was just trying to understand how antipopd executes. Thanks.

Seems like it‘s not compatible with Big Sur, can someone confirm this or does someone have a solution?

Is it possible to add second timer which will record audio? To prevent clicks on recording.

Not a criticism, but it doesn't compile on a bog standard (in this case M1) Macbook Pro.

Thanks for coding the project, amazing how annoying a pop in the ears can be every 20 seconds!
