[Solved]Audio works, but is not set as a default device

I have a fresh install of arch linux with xfce and lightdm installed and working.  The PC is a Intel NUC with only 2 HDMI ports for audio and video. I'm connected to port 0 HDMI.  aplay -L shows:

null
    Discard all samples (playback) or generate zero samples (capture)
hdmi:CARD=PCH,DEV=0
    HDA Intel PCH, HDMI 0
    HDMI Audio Output
hdmi:CARD=PCH,DEV=1
    HDA Intel PCH, HDMI 1
    HDMI Audio Output

I have sound if I play a video with vlc, but only if I change the device in vlc from default to HDMI 0

None of the speaker-test stuff from the wiki works.  From other post I saw why alsa-state.service was not running and fixed that with adding the ! in ConditionPathExists=!/etc/alsa/state-daemon.conf

I also added the file /etc/asound.conf

pcm.!default {
    type hw
    card 0
}

ctl.!default {
    type hw
    card 0
}

So what am i missing??

can you repost that without any adjustments in any config files? And

aplay -l

as well please

That change is misguided and incorrect (there are 2 files for 2 distinct, but separate and incompatible, ways of resetting mixer state, that conditional exists precisely to prevent both of them running at the same time), and also irrelevant to your problem even if it wasn't.

I also added the file /etc/asound.conf

pcm.!default {
    type hw
    card 0
}

ctl.!default {
    type hw
    card 0
}

As mentioned in the wiki this is an overriding, and breaking way to change your default, and really shouldn't be used as is if your entire intention is to only change the default device.

The least invasive fix is to change the defaults node as explained in this section Without seeing your aplay -l I can't tell you the exact line but interpeting from what we have, should be something like

defaults.pcm.subdevice 3 #Check that number against aplay -l

instead of your current config

Re: [Solved]Audio works, but is not set as a default device

I have removed my /etc/asound.conf file and removed the "!" from the alsa-state.service file and rebooted.  Below is the results of aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Ah that really is the entirety of your sound card support? That reads weird, however in this case use

defaults.pcm.device 3
defaults.ctl.device 3

as your  /etc/asound.conf

Re: [Solved]Audio works, but is not set as a default device

Thanks, that solved it. Now with vlc set to automatic audio it will play with either Default or HDMI 0

Also speaker-test -c 2 works
