I've tried to set up a Bose remote to my TV and B Ray player. I can get the programme change, menu and the channel guide working but not the volume + or - .I've tried other codes as instructed.

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.
