Oh, the "audio" button is the one with the code 0x01 that I mapped to KEY_AUDIO (thinking that it would switch audio tracks), but later I found that it goes to the music menu.
What KEY_ mapping should I use to switch audio tracks instead? And what mapping to go to the live tv section (KEY_TV doesn't)?
Other keys that apparently do nothing are:
- KEY_HOMEPAGE (home button on the remote, code 0x0d)
- KEY_FAVORITES (fav button, 0x1f))
- KEY_MENU (menu button, 0x45)
- KEY_APPSELECT (apps button, 0x58)
- KEY_WWW (browser button, 0x18)
