The IR signals you've learned are in the format shown in the spreadsheet linked in post #2, but the your remote is sending Device =1 with Vol+=35 and Vol-=34. The signals in post#4 (said to be tested) have the same format, but are Device 0, with Vol+=10, Vol-=8, and Mute=11. I think that the component you're trying to control and the OP's are different
The Velleman format allows for 7 device numbers, and 64 function numbers, so Mute could be a lot of possibilities.
However, I suggest you try the following Pronto Hex: Please first test the following hex codes for Vol+ and Vol-, which are very similar to your learned codes. If they don't work, there's no need to try the potential Mute codes.

Here's the IRP file I used with
MakeHex to generate these. I find the
MakeHexGUI to be a convenient front end for MakeHex.
