Question edited for clarity.

No one buys Universal Remotes these days, they are so 1980! You buy a Facsimile Remote, an exact copy of the original like this one.

I would look the code up on the remote manufacturers web site list.

AVOL 4 digit codes:
2735 1820 3382 2051 2397 3118

AVOL 5 digit codes:
13118 13382 13479 12735 12051 12397 12278 11531

for every remote control device ever made since the beginning of remote control devices?

No problem, but next time, PLEASE give us some clues!

wharfdale TVs are rebadged by Argos, so I am unsure of the actual manufacturer, and therefore the control signal scheme that they use.
It might help if you gave the model number of the particular TV, as they could be using several different manufacturers in their range of televisions.
it is unlikely there will be a single code that covers the whole range of Wharfdale Tvs

I have had very good luck with this site:

Great remote but not always easy to find right category for device.
Had a look for you and sure enough the device IS listed in data base under AMPLIFIER- then select amplifier again and input vizio for make and soundbar for model and click next.Problem solved!
