No Sound with Manhattan HDMI Audio

Hi All,

I have been trying to get audio working through my HDMI port on my Asus K52JT. I am trying to connect it to my LG Scarlet tv (which by the way is being detected as 32" when it is a 42"). I have no problems when i use my Win 7 Desktop to view/listen.

I have been trying a good part of my weekend to resolve this. Sorry if this has been answered somewhere else, i am feeling a bit desperate lol. I am running kernel 2.6.39 (testing) x64 wasnt working with .38 either, Gnome 3 (so pulseaudio and no catalyst). My device is detected in the Sound settings but when i Test Speakers nothing plays (the icon changes color quickly) and it doesn't play when using aplay...but no errors etc are given and it doesn't play properly. When i run it with time you can see that on the Internal Audio it plays the whole way but on the HDMI audio it doesn't...I have also followed the instructions given here https://wiki.archlinux.org/index.php/Ad … s_Not_Work but they do not work.

Does anyone else have this problem and or workaround?

Thanks in advance

This is the Internal Audio

time aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Left.wav 
Playing WAVE '/usr/share/sounds/alsa/Front_Left.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

real    0m1.542s
user    0m0.003s
sys    0m0.007s

This is the HDMI audio

time aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Left.wav 
Playing WAVE '/usr/share/sounds/alsa/Front_Left.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
