HDMI sounds

Hi,
I am using Arch Linux i3,
I have problems with audios. I want to play audios with my HDMI devices, but it does not have sound. (I tried to play some youtube video with firefox)
I am following https://wiki.archlinux.org/index.php/Ad … s_not_work.

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC1220 Analog [ALC1220 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1

  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 11: HDMI 5 [HDMI 5]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I found the following code word, and I can hear sounds
aplay -D plughw:1,9 ../../usr/share/sounds/alsa/Front_Center.wav

Then I changed my .asoundrc file to the format that wifi specified.
I tried all methods in the wiki, but none of it works.
1. I tried .asoundrc as

pcm.!default {
    type hw
    card 1
    device 9
}

and

defaults.pcm.card 1
defaults.pcm.device 9
defaults.ctl.card 1

and

pcm.!default {
    type plug
    slave.pcm "hdmi"
}

Can anyone help me?
Thank you so much.

Re: HDMI sounds

Post your .asoundrc and which program you are using that you have issues with. Do you use pulseaudio? Post the .asoundrc wrapped in and change your existing post to use [ code ] [ /code ] tags without spaces for pasting output

Re: HDMI sounds

What does pulseaudio for? I don't think I am using similar software.
