Sorry for my English. I have N550JV ASUS laptop.

I connect laptop to TV for HDMI. The image see in TV, but it listen sound in TV. I install oem-audio-hda-daily-dkms and active sound-hmdi exists in sound-control, with hdmi5.1 and hdmi-stero options. I select whatever options, but no sound in TV. I see alximer, but no mute sound.

aplay -l

The laptop uses two graphic cards, Intel and NVidia, but I see it uses Intel card for video and sound.
