No HDMI Sound OpiPC/Armbian

[DeterminedOpier]

Hello all.  

 

Try as I might, I can't get HDMI sound on my OpiPC.  

 

orangepi@orangepipc:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: audiocodec [audiocodec], device 0: SUNXI-CODEC sndcodec-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: sndhdmi [sndhdmi], device 0: SUNXI-HDMIAUDIO sndhdmi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

 

I originally had no asound.conf, but I made one:

 

pcm.!default {
   type hw
   card 1
}

ctl.!default {
   type hw
   card 1
}
 

Looking around, I see an unanswered question on this from '16.  HDMI on the TV does work with a Meego stick. 

 

I did have audio through the headphone jack before I went and added the asound.conf and edited the alsa config file. But HDMI just refuses to work.

HDMI sound works for me on a legacy desktop version with Orangepi PC.

Whenever reporting some malfunction, provide as much useful data as possible. We operate too many boards.

Yea it didn't make any sense to me. That was why I tried it with another board and it worked fine.

I actually see hdmi.audio=EDID:0 but I have no idea how to change that to 1.

Hi again Igor. Thanks for explaining the utility. I hope at some point you'll come back.  I have a new development.  Burned an image of retrorangepi and lo and behold, the HDMI sound works.

 

So I may try to make this image do what I need it to do for my main project. But I'd still like to get the base image working correctly.

mine has one line more - on many different Pi-computers - doesnt know if this line does the magic:

 

pcm.!default {
    type hw
    card 1
    device 0
}

ctl.!default {
    type hw
    card 1
}

 

because

card 1: sndhdmi [sndhdmi], device 0: SUNXI-HDMIAUDIO sndhdmi-0 []

Thanks. But didn't work.  I also tried copying the asound.conf from the HDMI sound working image from retrorangepi and that didn't work either. They have this whole dmixer thing going on there, and I did an apt-cache search on dmixer and got nothing. Wish I could get the dongle to work on the other image at least. It's like a circle. One does one thing I want and the other one does the other thing, but ner the two shall meet.

Lol I didn't give any information and my methods have failed.  Just tried to burn a fresh image for the opipc and same issue, sound through headphones but not through hdmi. Fortunately the TV has an 1/8" audio in.  It looks like on the retrorangepi image they used some fancy software footwork to get the hdmi to work.

Igor replied in the opi board. 

 

I have no idea how to switch from analog to HDMI.

It is very simple and it works. I just checked on latest Ubuntu desktop image with legacy kernel. Click to audio settings/icon in upper right corner and switch "Default sink" to sndhdmi analogue stereo

I tested playing this video http://samplemedia.linaro.org/H2 ... fps_7200K_short.MP4

Those are logs from image: http://sprunge.us/WUDf where HDMI audio was tested successfully. Board is Opi PC+
