Hi I a running Ubunto 12.04 on a HP PC with an onboard intel analaog sound card

(ALC662) and a HDMI connection into my TV.
I use this PC for Mythtv and Kodi using the sound over HDMI which works a treat in MythTV however I cannot get the sound to work on Kodi, Firefox or any other app which I presume is down to misconfigured ALSA setup, I had this working previously but it stopped and I am not sure why, possible updates.

Heres my /etc/asound.conf

pcm.!default hdmi_complete


Any help would be greatly appreciated as I dont fully understand ALSA and its

driving me up the wall :-)

Thanks

try running alsamixer from the a terminal and ensuring that you don't see MM on the master channel.

Hi

Yes have tried that and can confirm that no channels are muted, thanks for the reply.

TomC

Or any other channel, for that matter. The MM at the bottom would indicate it was muted. Use the right and left arrow keys to change which "slider" you have selected, and press the "M" key on your keyboard to unmute it.

Also, make sure no important-looking sliders are all the way at the bottom.

Hi

Can confirm that this is not an Alsamixer issue, it is down to config and asound.conf but what exactly I am not sure, many thanks for your help.

Ok I remember having a similar issue on another machine which had both HDMI and digital sound. The only way I could get it to work was using a pulseaudio graphical tool and selecting my hardware and testing. But that was under manjaro not sure if Ubuntu has the pulseaudio configuration tools installed.
