Fred, if you re-install the Realtek driver and the issue persists then it is a hardware problem. When you re-install the driver it resets to the default configuration settings, so you eliminate configuration as the cause of the problem, and the cause is not the driver itself or else it would be more wide-spread.
Alternatively, you could remove the Realtek driver entirely (by using in the Control Panel "Remove a program" or "Programs and Features"). By removing the Realtek driver you force Windows to install its native driver upon rebooting. If the issue remains with the native driver that also confirms it is a hardware problem.
Thinking about this some more, after eliminating the driver and configuration, the only possible causes left other than hardware are Windows and BIOS. If either of those were the source it should be a known problem but it isn't.
A possible reason that the F12 test was no help is that Dell is no longer including the full Dell 32 bit Diagnostics utility in the newer models, so the only tests on the diagnostic partition now are the PSA tests or ePSA, and the audio in those tests consist of system tones. System tones bypass the headphone jack and go directly to speaker.
Thanks for your explanation, and thanks for thinking about the issue further. No wonder when I booted into the Diagnostic Test, I didn't find the Custom Test option. It is a pity that the full Dell 32 bit Diagnostic utility is not in XPS12...
I thought about the possibility of booting a Linux Live CD to see whether it is Windows's problem or not, but I don't have an external USB CDROM drive. I guess I better not mess with the system too much at this stage.
I was wondering if you ever got a solution for this problem. I have recently bought an XPS 12, and whenever I plug in headphones, it makes (I assume) the same kind of tapping sound you described. The actual audio also stutters and becomes completely unusable. Any ideas?
For the problem I experienced (i.e. headphone jack tapping sound but internal speaker okay, and uninstalling driver didn't help), I contacted Dell and was first asked to try the latest BIOS A07. The BIOS update didn't help. So Dell were quick to send a technician out to replace the audio logic board on-site. After the audio board was replaced, the headphone jack worked again. So in my case, it was a hardware fault.
If you tried the same tests/steps above and still have the same problem, then yours is likely to be a hardware issue as well (in my opinion).
