When you change the audio/subtitles/chapter using only the remote, you don't receive any feedback from the stb. You need to query the system registers to get the updated value, but you can do that once the user open the popup or topmenu.
What you can do is to block the audio/subtitles change via the remote (using the UO mask feature) so the user is forced to change audio/subtitles using only the top/popup menus. Then, you can change the subtitles once the user change the audio. The SetStream command can change both the audio and subtitles at once.
