Jack and HDMI audio doesn't work


Hi everyone,
Foremost, I’m a new user of this kind of OS, I always had a Windows.

I’m trying to connect a Jack and a HDMI wire but the audio signal doesn’t pass through.
Even when I route it to the right Output via PulseAudio.

Am I the only one?


Pulse audio is not the default sound system

can you type --> about <-- then paste here?


How are you routing it to the right output in PulseAudio?..

Maybe i’m wrong, graphical interface let me choose the output of audio signal. This graphical tool is PulseAudio, isn’t it?


How can I install the audio driver shaped for my audio card?

What is the output of this command:
$ pciconf -lv |grep -B 3 -A 1 multimedia




Here is the output:

hi, I’m interested in this issue treat because I’m having more or less same on my new 18.12 installation, similar to what I had in previous 18.03 system. 3 different output sound devices appear in my Mixer Tray : pcm0 Intel Broadwell (HDMI/DP 8ch) , pcm1 Realtek ALC282 (analog) and pcm2 again Realtek ALC282 (analog). None of those device gives an hearable sound to speakers or hearphones, although the devices appear active/selectable and with their volume settings level in the Mixer. In my previous 18.03 installation I could workaround this lack by plugging in a cheap usb sound board which, once detected, appeared in addition of those three devices in the output audio gadget and could play sound connecting the audio jack to it. With 18.12 nothing happens when I plug it in, it does not appear at all among the audio devices.
However, if this can give useful indications about what is happening in my audio device section, here below is my output after the command line you suggested:

hdac0@pci0:0:3:0: class=0x040300 card=0x80c2103c chip=0x160c8086 rev=0x09 hdr=0x00
vendor = ‘Intel Corporation’

vendor = ‘Intel Corporation’
device = ‘Wildcat Point-LP High Definition Audio Controller’
class = multimedia
subclass = HDA

thank you

# cat /dev/sndstat



Installed devices:

No devices installed from userspace.


Oh wait! My jack output is now working.
More news about my HDMI soon.


is that random or you made something specific?
I’m also starting to believe that the reason of the missing usb sound device detection could be a matter of permissions, maybe also having to do with the missing main HD volume (Windows) detection with Insight file manager…


Nothing specific.
Came back into the mixer after I’ve selected the Realtek (0x0668) (right headphones analog).
“Recording…” and " Default tray…" on “vol” -> “TEST” It works now.

vol/pcm/igain/ogain? What is it?

EDIT: HDMI audio doesn’t work… and the video that I put on the second screen (HDMI) doesn’t play anything other than an error message that invites me to reboot my device if the video doesn’t start in a little while…
