Hmmm. Puzzled, then. It makes a very slight chugging sound, similar to,
but not exactly like*, a bad bearing. It is almost inaudible with the
side installed on the PC, though.

I've never come across a PC fan that won't spin by hand when powered
off. It sounds like it's either powered but not enough to overcome
friction to start (eg low voltage or speed control set too low), or
bearings badly binding.
As you say it's not spinning when unpowered (ie PC turned off), that
rules out the first one. I'm thinking it would be worth changing the
fan.
It sounds like this is probably a red herring in relation to your
capture card issues.

When I was setting it up, I noticed that I could not hear any sounds,
even though there was a speaker pair plugged in. Adjustments to the
volume control eventually produced some Test sounds, but only with
both the Volume and even the 'volume amplifier' setting both at
maximum. The sound could just be heard with the speakers held close to
the ear. The manufacturer suggested going back into Windows, and
downloading a Driver Downloader Uninstaller, which would clean out and re-install the Windows sound drivers. But even if this works, it's in Windows, not Linux. Trying to install and run this was a mass exercise
in demonstrating why I hate Windows.
I hate to think about sending it back, with all the hassle involved,
when I don't actually need sound on this particular machine. I have
installed Zoneminder, (quite a long process there), and I have purchased
a PCIe-to-PCI adapter card, but I have not installed it yet, pending
the final decision on what to do, if anything, with the sound problem.
They are sending me a Windows driver of some sort to help, I hope. The non-activated Windows will not let me access the Windows settings to
test the speaker output.
I am going to try playing about with alsa-mixer and pavucontrol to see
if they help at all. After lunch, that is.

I don't like refurbished PCs, anyway.
You may have a problem with mounting - the adapter card adds maybe
1-1.5" to the height of your card. Depends on how tall your PCI
card is. You'll probably need to take the backplate off, but it
may be short enough to fit in a full height PCIe slot.
If this is problematic you can get PCIe 'riser' cables. Random
example: https://www.amazon.co.uk/GLOTRENDS-Riser-Function-Features-Degree-Black/dp/B0CHRZQNRK/
(various lengths and x1 / x4 / x8 / x16 available, many different designs)
and then mount the card elsewhere in the case.
If you're buying a new PC anyway there are a few mobos with native
PCI slots: https://uk.pcpartpicker.com/products/motherboard/#d=1,6&sort=price&page=1
Most of them are for old CPUs, but those with AM4, AM5, LGA1200 or LGA1700 CPU sockets are fairly modern: https://uk.pcpartpicker.com/products/motherboard/#d=1,6&sort=price&s=33,41,39,40

Thanks. I will probably get the PC first, and then I can look inside
and see what space there is, and therefore what I need to get to a
PCI slot. Luckily, my existing system is still working, so it is not urgent. I will continue to report progress.
The new PC is ordered, from PC Specialists, who provided my laptop. A
shame they don't do Linux, but nobody is perfect. I will install that
myself.
First, I will get it sorted without any hint of Zoneminder, it's other
job will be to take over as my daily backup device. I will also take
a look inside to see what room there is for PCI adaptors.
That is why I am going to play with alsa-mixer. It's a long tie sonce I
last did, but it worked then.

Are you sure you aren't exporting sound via the HDMI (or
Displayport)? It's a common way to use monitor/TV speakers nowadays,
and it's possible the sound is going there - but if your monitor
doesn't have speakers then you wouldn't hear anything.
Although it sounds like the audio output does work, but perhaps the
mixer volume is wrong. That could be influenced by software.
Have you tried headphones, in case it's something related to the
speakers?
Do the speakers need external power? I used to have a set where they
would be passive if the internal amplifier wasn't powered, resulting
in much quieter volume.

Worst case, a USB audio output dongle is less than a tenner.
Probably less cost than the postage to send it back.

I was recommended to watch this video: https://www.youtube.com/watch?v=_MIoC-CdEQw
which explains, sort of, how to install one of these cards. But I
am confused about at least one thing. I am sure there will be more as
(if) this progresses.
In that video, he uses Windows. After installation, he then* calls up a screen (BIOS?) that tells him whether or not the PC, a UEFI one like
mine, sees the new card that he then installs. Will this be the same on
my machine, and if so, how do I configure the BIOS to allow the legacy
BIOS to be seen and used?
I am clearly well out of my comfort zone here!

I think you're using it just for the video capture card here?
In which case it doesn't matter if the BIOS doesn't see it, because
you're not booting from it. It's fine if the card is ignored until
in your OS, since your OS will boot from some SSD/HDD that's not
connected via the PCI slot. The BIOS doesn't know or care about the
video capture card, it's only bothered by discs and displays (both of
which Adrian was trying to get to work), and the capture card doesn't
have any firmware on it that's run at boot.
Once the OS is booted, I think Linux will likely support such a
PCIe-PCI bridge out of the box - there are no drivers you can
install. So either it'll work or it won't, but probably you can just
plug in the video capture card into the PCI slot and it'll be
detected in Linux (check 'lspci').
As the video suggests, things can be variable though. I tried one in
the reverse direction - PCIe card in PCI slot, in a RISC OS machine
not a PC - and just its presence stopped the machine from booting.
But new into old is probably harder than old into new.

I installed the first card that plugs into the motherboard, and ran the
USB cable out through the next backplate slot, as that is where the
video card will sit. For now, the PCI board sits on top of the PC, the
bottom of it is well protected from touching anything. Later, it will
hang off the rear of the video card, assuming I get that far!
Due to operator error, I didn't see what happened, if anything, on the
screen after powering up the PC, but the new PCI slot board has the
little blue light glowing, which implies that it is happy.
But the SATA cable supplied as a spare part with the PC has a different connector for the PCI board end, it needs a 15-pin connector instead of
a 7-pin. The supplied cable has a 7-pin plug at each end.
I am confused about the gender of the socket on the PCI board, is it
male or a female, the difference seems to be very small to the untrained
eye?
https://www.amazon.co.uk/dp/B0CXSYTRH3?ref=ppx_yo2ov_dt_b_fed_asin_title
shows the board. I will assume that the SATA connector is female,
needing a male plug, but another opinion would be welcomed. I am in an unknown world here.
But looking at SATA cables, maybe the PC motherboard, which is described
as having 6Gb/s SATA sockets, may not be capable of supplying actual
power? I am confused. Again.

The SATA connector is for power, because the USB 3 cable can only
carry a small amount of current from the motherboard. Plug in a SATA
power connector from your PSU and you can power a beefy PCI card like
a GPU from the PSU directly.
It doesn't want anything to do with SATA data from the mobo.
It may or may not work without the SATA power cable being connected,
but better to supply power via the SATA connector and avoid brownouts.

Thanks for the encouragement! Yes, it is for the video capture card,
but to leave that in operation in the old PC until I am ready for it,
I have an old but unused Wifi PCI card available, which I hope will do
the job of test mule.
More when there is more.

The SATA 15pin connector is to supply power to the PCI slots, if your

you could get a molex->sata cable e.g.

that one just has red 5V and yellow 12V, I highly doubt yu need the

PCI is +/-12V, +5V and +3.3V. Some cards are 5V and some are 3.3V.
Depending on how lazy the adapter manufacturer has been, I wouldn't be surprised if the card needs all these rails to come from the PSU,
rather than taking 5V and regulating it down.
There's no voltage conversion circuit on the front of the board - no
pics of the back, but I suspect they cheapskate out of it. So I
wouldn't assume a Molex adapter will work.

When I powered it up for the
first time with the video card installed and powered, there was a
warning about Fan speed. I looked inside, and the fan was not
running, but a quick tap made it start. From then on, it ran at varying speeds, so something is affected. Maybe the PSU is a: Underpowered

I suspect the fan's bearing has dried up and powering it off/on, or
moving the case about has given it a chance to start acting up, dab a
drop of light oil on the bearing, perhaps?

I'm confused - I thought you were talking about the fan on the video
capture card that you transferred from the old PC? Or do you mean a
fan on the CPU / GPU / motherboard / in the case?
Modern PCs have variable speed fans - like laptops, they only spin
the fans as fast as they need, based on temperature sensors. So
changing speed is a feature not a bug. Although I wouldn't have
expected speed to change based on a tap, perhaps it was coincidence
that it happened to decide to spin up the fan at that time?

Yes, it was the fan on the motherboard. When I powered it up, I was
given a warning that there was a problem, and told to open the BIOS,
which displays fan speed. Once I had tapped the fan and started it
spinning, the speed display matched the sound of the fan, as it went
into speed ranges that I had never heard before. Maybe it was just
getting the temperature sorted out.
The next time I boot up, without the video card installed, I will go
into the BIOS and watch what happens.
Ok. I did some testing yesterday, trying to pin down what is happening.
When I boot up the PC with only the adapter card connected, without the
SATA cable, it always works with no problem.
But once I start to add more, such as the SATA cable, the fan control
has difficulties. Often, if the message comes up that there is a
problem, and to go into the BIOS, just doing that and waiting for a few minutes will let it sort itself out. Nothing needs to actually be done.
I tried it with the video card installed, and it really did not like it.
It still sorted itself out, ...

I think a PCIe card can draw max 75W from a dlot (presumably the second
slot is unoccupied?)
Not sure how much power a SATA cable can supply?

The card I looked at is:
https://tinyurl.com/26k8uy3b
It is just about mentioned on the company website, buried
deep in the Unsupported file. There is no mention of available
documentation. The vendor says it was used in a Windows system, so has
no idea about Linux use. My question is, is it
possible/probable/certain that my Ubuntu would pick it up and go with
it without any any further configuration?
It seems like something is wrong, but unclear what. Fans are usually
powered from 12V, so perhaps the adapter did something bad with the 12V
rail?

According to the writing on the chips, it has: https://www.linuxtv.org/wiki/index.php/Conexant_Fusion_878A
behind a PCIe to PCI bridge:

The above page says it's supported by the Linux bttv driver: https://www.linuxtv.org/wiki/index.php/Bttv
So looks promising.

Indeed I ran a couple for ages (PCI not PCIe) work well
