That is very odd. There is nothing different from the versions except the channels.
I can send you some other channel builds to test.

Devin, Over the weekend, I changed my default system audio (mic, speaker, alerts) to all non-BlackHole devices. And this morning I noticed that "BlackHole 16ch" was still working but the 2ch and 16ch ones were not (they "disappeared" and the format in Audio MIDI Setup went to 44100 Hz. I am wondering if the pkg that you have for those 2 are somehow "incorrect". Can you recreate them and send me updated ones to try? Or if you have another configuration (32ch?) that you want me to try, send it to me. At least now, I know how to "restart" BlackHole without restarting the computer or Chrome. — Reply to this email directly, view it on GitHub, or unsubscribe.

Once the MacBook sleeps for more than 1 hour, the BlackHole 2ch and 64ch format goes from 48KHz to 44.1KHz. I've tested this a few times and I can repeatedly see this happen.
I still haven’t been able to reproduce. BlackHole 2ch and 64ch channel remain at 48kHz no matter how long or how often I put my computer to sleep.
Do you have any other applications that use audio running?

LadioCast and Zoom Meetings is running. Google Chrome sometimes would run Google Meet. That is pretty much all the apps that touch audio.
Could you do a test to try to reproduce this without any of those apps running?

Will probably have to wait until the weekend.
Oh I also have the Microsoft Teams Audio driver installed from the Microsoft Teams meeting app.
I assume that solved the issue. Reopen if not.
Solved? Nope. With what solution? It is still doing it (changing the bitrate from 48k to 44.1k on the 2ch and 64ch driver). It does it with nothing open, except Audio MIDI Setup (only to see the bitrate format).
As in it's Microsoft Teams that is changing the sample rate.
I'm stumped. I can't reproduce. And nobody else has reported this issue.
What you could do as a work around, is build a custom version of BlackHole with only 48k sample rate.
It is very odd that it only happens with the 2ch and 64ch versions. The 16ch is fine.
Hi,
I'm using latest blackhole-2ch installed via brew (blackhole-2ch: 0.2.10) on macOS 12.1, MacBook Pro (14-inch, 2021), M1 Pro.
Unfortunately, the blackhole audio device keeps disappearing after some time. Only my script to restart audio helps:
It might be related to Xcode and/or simulator, because I'm using blackhole to redirect input/output from the simulator. Without the blackhole I'm often hearing some strange crackles caused by the simulator, that's why I installed the blackhole.
Could you check this?
