As google gave silly results, here comes my problem and it's fix (not any more, see below):
I experienced audio dropouts that very strongly hinted to a loose connection
or floating contacts on my 10$ Apple Lighting to headphone dongle:
After plugging it into my Iphone, sometimes only shaking would make it loose contact.
Tapping on the 3.5mm connection did make the dongle loose connection,
or simply sliding the phone into my pocket.
While trying to reconnect one would hear a toc-toc-toc popping sound
on the earphones (the same pop you hear when the phone amp switches off) but no avail.
Sometimes disconnecting and reconnecting would help for a short time.
Other things also hinted to a loose contact: The Lightning connector has a tad of play, rotating the
3.5mm jack in the connector would make a scratchy sound as it was corroded.
I use a Koss Porta Pro with an "unofficial" Talkback/Volume Control,
(that does not work on an Iphone anyway)
So I soldered on the Koss a new classical 3 pin connector
to check if the dongle works better when it "sees"
a dumb headphone from the Walkman/ Discman times.
Also the 3-Pin connector was new and not corroded.
But the problem remained, audio dropouts that hint to a bad connection.
I was very close to even replace the 3.5mm plug of the dongle
with a better one - all electronics are in the Lightning jack, the 3.5mm plug is passive.
But before doing this mod, I checked
Settings > Sounds and Haptics > Headphone Safety > Lighting Adapters > Forget all adapters
"Lightning Adapters" only comes up, when a dongle is plugged in.
"Forget all adapters" - it is now missing while I type this, maybe because I confirmed the command
helped, the Problem is gone. The dongle works flawlessy.
I do not know what triggers "Forget Adapters" to come back.
Maybe when I plug in the charging cable later... IOS is 15.2.1 btw
EDIT: The problem came back - And "Forget all adapters" does not show up yet.
But it must be there:
