antix live - how to set sound output to hdmi

[Laurentius]

Hello.
I have connected my tv to hdmi on netbook.
I could get display output fine but no luck with the sound. I can t find how to set the sound output to hdmi.
after trying on control centre I have installed pulseaudio and pavucontrol. If I launch pavucontrol, in the configration tab says "no cards available for configuration".
May be some step is missing.
Do I need pulseaudio for this or is it possible with default antix and alsa alone?
The card is HDA intel PCH.

And this is the output of aplay -l

So, I think I should use device 3 as output. But I don't know how to do that.

Looks like you have one device:

Audio:
Device-1: Intel Atom Processor Z36xxx/Z37xxx Series High Definition Audio
vendor: Elite Systems driver: snd_hda_intel v: kernel bus ID: 00:1b.0
Sound Server: ALSA v: k4.9.160-antix.1-amd64-smp

Control Center and choose hardware See attached image
Choose Sound card, if you have hdmi capabilities it will show up in "Sound Card Chooser" and you can test the sound -
You might need some powered speakers with volume control or maybe you already have a descent wired headset

See my antix sound problems in thread: viewtopic.php?f=107&t=45796&start=10 Message # 13 from Jim how to set sound in the mixer...

Oh, yes. There is only one sound card on that netbook (card 0: PCH [HDA Intel PCH]), I was referring to the aplay -l output. where Hdmi is related to device 3. I don't know what that means.

"Only one sound card was found PCH: HDA-intel - HDA intel PCH Nothing to do" That's what the "Set default sound card" window at the Control Center says.
Nothing about HDMI there.
While in Antix, I can hear sound through analog stereo (speakers and headphones). But I haven't been able to get sound through HDMI with Antix.

The device has HDMI capabilities. It works with MX (selecting hdmi on the pavucontrol window). But I was trying to use it with antix (and, if possible, without pulseaudio).

Thank you namida12 for your reply!

I have the same issue, any help would be appreciated.

There is some finagling needed to get the hdmi output correct. Once you have it setup you can make a udev rule to automatically switch the sound outputs on inserting an hdmi cable. Myself I have used arandr to setup the video output, saved the video output (which is a script). Then added the commands to switch asoundrc files around and restart alsa. That way I can run the script to set the video and it also sets the audio (and one for back to normal).

The arch wiki has a nice quick guide for figuring out the alsa hdmi output.

Thanks for the reply and the link.
Unfortunately in my case it seems I may need to patch the kernel (something which I have no clue how to do):

PCM through HDMI does not work (Intel Gfx)
To make it work in Linux 3.1 you need to apply the following patches:
drm: support routines for HDMI/DP ELD
drm/i915: pass ELD to HDMI/DP audio driver
