I've tried the solutions above on my MBP Catalina OS, the only one that really works is removing WhatsApp Web, mine even affects my Bluetooth mouse. Today alone, it has both disconnected and reconnected by itself twice. My headphones disconnect or drop-offs even more often, I count 6 for the last 5 work hours. Hopefully, there's an update on this issue.

This is not necessarily a macOS or Apple problem. My thought is that you have an issue with the Bluetooth device itself. The BT device being connected isn’t a big factor here (well, you obviously need to be connected to transmit data, but that’s not what I’m referring to, here). The radio signals BT uses isn’t that much different than two way radios ...

I talked with the company that sold me most of my system (but not the Mac - just everything else) and we couldn't find a solution. I called Metra, the people who make the HDMI switch and one of them suggested something I could get from Amazon. It cost me $22.49 and fixed it. I don't want to advocate for a particular brand, but what I found seems to not ...

The problem was fixed by itself. Mac froze for some reason, I forced it to reboot, the problem was fixed.

I'm wondering if there's a way to override and tell sound, "Just send through the HDMI output." No. You can’t do this because this is not the way it works. You’re treating this as if it were an analog audio signal that you’re just going put on the wire and it’s just going to be there. HDMI is a digital signal which encapsulates both audio (compressed ...

Since the AirPods don’t have a mode until they are in your ears there’s no mode before you have them live. Once they are live that data isn’t exposed on AppleTV. I would recommend using the switch control on your AirPods to cycle the mode until you know what mode they are in by listening.

You have the exact opposite symptom, but exact same problem as described in the question Force sound's output on speakers. Basically, the audio jack is broken. There’s a physical switch that’s stuck in “speaker mode” and it cannot be switched via software.

There's a lot of talk about 'lossless audio'. There's also a lot of opinion surrounding it, much of which doesn't come from sound engineers but from people who are chasing the wrong part of the rainbow ;) To really simplify, Lossless audio is that which can be uncompressed to produce exactly the same data that was originally encoded. You need this if you ...

This is very much possible using ScreenFlow: https://www.telestream.net/screenflow/overview.htm It's a paid app but very high quality and straight forward to use. Whenever you create a new recording it gives you options of recording audio/video from all available inputs, including the screen, camera, microphone, and internal computer audio.

I tried all these things, but they didn't work. Eventually switched my wifi to 5GHz and the problem went away. Ref: Bluetooth and WiFi interfering with one another since Yosemite

I created a script that does all of what @edd-growl mentions above, for you. https://github.com/alb12-la/KBOS

I had the same problem. I did everything that I found within the different communities and blogs, finally, I find out that there is something between Whatsapp and Bluetooth. I uninstall WhatsApp and never use WhatsApp web again and problem solved. I hope it can help in your case too until Apple figures out how to fix it.

You really cannot measure the latency "through" the OS because of the overhead of queuing and managing the processes. To be "more accurate" you'd need to write a program that could directly access the kernel so that you could evaluate the actual time between events - the beep and the keypress. However, you can get fairly close in bash by using the time ...

First off - using echo -ne '\007' to play audio is not "low-latency" audio. I.e. this command in itself could take a (relatively) long while to actually play the audio. Therefore using it to measure response times in units of milliseconds is not going to be precise at all. A way of measuring it would be to use an audio recorder of some sort with known low ...

I was trying to get my Sony wh-1000xm3 headphones to work in AAC / aptx (they were stuck in SBC despite following the usual guides) . I was unable to get them to work as expected until I enabled the "Priority on Sound Quality" option in the Headphone android app. Presumably the same option exists in the iOS app

Just pointing out that the latest driver (from April 2014) for the UD-H01 (same for A-H01) still works fine for me with MacOS 10.14.6 on a Macbook Pro from 2015. It's important to follow TEAC's install guide (updated 2018), i.e. don't forget to enable the kernel extension after the system reboot. Since the CoreAudio driver of MacOS works "somewhat" (for me ...

I've got a set of Android compatible wired headphones. For some time I've been looking for a method in software/firmware to make the 3.5mm port on my MacBook read the ground and mic inputs appropriately (as per Allan's answer), but to no avail. However, I've found that controls such as volume up and down work when using a 3.5mm to USB-C adapter. I have a ...
