    12.04 Sound not working through HDMI

    I have lubuntu 12.04 on Vaio VPCYB15AH laptop. I don't get any sound on TV when connected through HDMI. The corresponding control in alsamixer is unmuted (Screen below).



    ┌───────────────────────────── AlsaMixer v1.0.25 ─

    My aplay-l output below:
    $ aplay -l

    **** List of PLAYBACK Hardware Devices ****
    card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]

    card 1: SB [HDA ATI SB], device 0: ALC269VB Analog [ALC269VB Analog]
    Subdevices: 0/1
    Subdevice #0: subdevice #0



    Any idea how to fix this ?



    Additional information w.r.t sound on this system :
    After installing lubuntu, I did not have any audio/sound output (Speaker, headphone, HDMI). I browsed the other forums and found that either of the solutions below enabled sound on speaker and headphone.

    1. http://askubuntu.com/questions/10622...u-installation
    First answer on swapping cards in alsa.conf worked for me

    2. http://forum.xbmc.org/showthread.php...025#pid1069025
    Editing .asoundrc file with hw:1.0 also worked


    So I can use both now with auto mute also working. But still unable to get audio working over HDMI even when video display over HDMI works fine.
