Hi Raymond, --> can you be more specific when saying: "use jack sense of 0x16 to change the stereo profile to surround5.1 profile of pulseaudio"? Also I read realtek's article but I am not sure to understand what SPDIF-OUT has to do with CEN/LFE... As you can see I am not really keen on ALSA & pulse technical stuff... :-(
--> Anyway, after some days of testing, I noticed another (very) annoying thing: I have to "Set the mode to "Analog Stereo Output" and then to "Analog Surround 5.1 output" in the sound settings panel" between each song I play to keep the CEN/LFE working. To be more clear, let's say: a. I start a song (e.g. using rhythmbox, but it is the same with vlc or banshee) b. I do the trick "Analog Stereo output"->A="Analog Surround 5.1 output" to make the CEN/LFE works c. I jump to another song d. At this point the CEN/LFE stops work, and I have to do again the trick "Analog Stereo output"->A="Analog Surround 5.1 output" to make the CEN/LFE works. I have no idea how to fix this problem as I am not developper. But it will be my pleasure to help testing or debugging...
