Burn a CD and check your car player with your tuner app. Check your iPod as well with some reference tone mp3 tracks. It's possible that your computer is OK and your car CD and iPod are slightly fast.

That is a very good idea. Might be a day or two before I get to it as out all day tomorrow.
Just want to say thanks again for all your help with this, it's really appreciated.

Hi again
Tried the three test files on my iPod. 440 and 880 were just 0.1 and 0.3 over, respectively and the 1760 was exact.
I've ordered a USB soundcard from Amazon which should arrive in the next day or two so once I plug that in, I can bypass the onboard sound which is where, I think, this slowness is coming from.
The reviews include good experiences from a few Linux users (Ubuntu, Xubuntu, Mint, Fedora and Debian were all mentioned) so hopefully it will do the trick.
Cheers

So have you tried enable_msi=1 or not?
Interrupt Handling
~~~~~~~~~~~~~~~~~~
HD-audio driver uses MSI as default (if available) since 2.6.33
kernel as MSI works better on some machines, and in general, it's
better for performance. However, Nvidia controllers showed bad
regressions with MSI (especially in a combination with AMD chipset),
thus we disabled MSI for them.
There seem also still other devices that don't work with MSI. If you
see a regression wrt the sound quality (stuttering, etc) or a lock-up
in the recent kernel, try to pass `enable_msi=0` option to disable
MSI. If it works, you can add the known bad device to the blacklist
defined in hda_intel.c. In such a case, please report and give the
patch back to the upstream developer.
No I didn't. I'll see how I get on with USB soundcard.
Cheers

I spent the afternoon tuning several electronic keyboards. I could tell the difference between 440 and 439 or 441, but I couldn't really distinguish 440.5 or 439.5 especially with the warble that exists in most older electronic keyboards. I find using gtkguitune convenient. I plug the line out of a keyboard into the line-in of a laptop and set the appropriate gains. You can see the variation and the ripple noise from these 20 and 30-year old keyboards. The timing accuracy of a thinkpad laptop is several times better than the analog circuitry in these old noise makers.

But isn't there something charming in that non-perfectness? That's why people like Orbital and the Chemical Brothers love the old synths.

Well, the USB soundcard arrived and seems to have solved the problem.
No slowness anymore and if anything it's a bit louder too.
For info, it was this USB soundcard and it works fine with Xubuntu. Simply plugged in and it just worked. No drivers, no reboot. It appeared as a new analogue device in the Pulse Audio sound settings, select it and that was it, job done.
Nice to read all the reviews from Windows users on Amazon talking about downloading and installing drivers!
Anyway, particular thanks to Temüjin for all your help. Learnt a lot about audio from you, mate, so many thanks.

It's a growing trend. As folks determine that their on-board audio sucks, they look for other solutions. For instance, RaspberryPi's have mediocre sound, so Wolfson steps in:

And yes, I do like that analog sound and working analog keyboards command premium prices as a result. (They are really hard to keep running.)
