It's likely that the wrong keyboard letter has been mapped to the remote button.
Below is an example on how to troubleshoot a keypress:
Scenario: When I press the mute button on my remote control it's not muting the sound in XBMC/Kodi.
Steps to troubleshoot:
- Connect Flirc to your computer
- Open up either an onscreen keyboard or a text editor:(Example of an onscreen keyboard on mac)
- Press the button on your remote which isn't working and the computer should show the button being pressed on the onscreen keyboard, or if you are using a text editor it will type that key on screen:
(This is an example of a remote control key being pressed and the text editor recording what flirc is sending to the computer)
- In this example the letter "i" is being sent when I press mute on my remote
- Check the software's keyboard shortcut guide, in this case kodi:
- The guide says that "I" is mapped to "Info" function:
F8 is the short key for "mute"
- Delete the incorrectly mapped key
- Then reprogram the correct key using the keyboard controller in the flirc gui
There can be other reasons for incorrectly mapped keys but this method helps narrow down the cause.
