Due to manufacturers adhering to standards to varying degrees, and manufacturing tolerances being all over the place, we do not live in a perfect world where these things 'just work' as they are supposed to. The issue is simply one of electrical metal-on-metal connections when you physically plug the jack into the socket. PS: Whether or not you actually use the microphone is irrelevant. If that behaves normally, but your two-band jack doesn't, then you know what the problem is. To test to see if this is your problem, find a plain headphone jack (only one central band) and plug/unplug that sucker repeatedly. In the majority of cases where hardware is at fault, folks plug in a jack with two central bands (headphones with microphone support) into a socket expecting only one central band (headphones only). If there is no clean contact, then the OS (via the audio subsystem) may either not recognise what you have inserted, or not recognise that you have inserted anything at all.
If the socket on your computer is expecting one type of jack, and you plug in the other type of jack, then you may not end up with a 'clean' contact. Many headphones have inbuilt microphones and, as a result, the headphone jack has one more contact than those that do not have inbuilt microphones.

#B450 tomahawk install
Performing a fresh install of PulseAudio after removing all configurations.Whereas the B450 model saw a 22 degree rise in temperature from the 3700X configuration, the B550 model increased by just 7 degrees and was 2C cooler than. By suspending and unsuspending the computer, the problem is usually fixed and headphones will now appear in sound settings. The B550 Tomahawk is even more impressive.Simply plug headphones into computer but headphones don't appear in sound settings.
Be running computer with headphones disconnected using another audio output.I'm certain that the issue is with Ubuntu 20.04 because the issue was not occurring (as far as I'm aware) when the same computer was running 18.04. I'm running Ubuntu 20.04 on a custom built computer with a B450 Tomahawk motherboard. The issue that I'm having is that headphones plugged into the 3.5mm jack on the front of my desktop computer are not always detected.
