[pulseaudio-discuss] Unable to create SPDIF profile (VT1828S)

[strykar at hotmail.com]

Hi,

I have an onboard sound card which has an SPDIF output via motherboard
header that I cannot get Pulseaudio to detect and manage.
ALSA sees it, (https://i.imgur.com/p4TdEAl.png) and it works fine under
Windows 10, though for some reason PA does not and instead lists a
Digital HDMI Profile on the card (in pavucontrol) when there is no HDMI
connector on the motherboard.

I have tried all the troubleshooting steps on the Arch linux wiki and
then some: https://termbin.com/w9do
alsa-info.sh log:
http://alsa-project.org/db/?f=d4b7b6cbf6b3b83cc42cc209a38a62b598332b6b

The card name is (alsa_card.pci-0000_00_1b.0) and 'aplay -l' lists it
as a VT1828S chip using the snd_hda_intel kmod.
If I try to manually add it with 'set-card-profile', PA fails to start.


Looking at termbin log, under "!!HDA-Intel Codec information" it shows:

I had managed to get this working a long time ago based on some tips
from #archlinux, but since it was a bit buggy, I stuck with the analog
line out and did not save that config sadly.
It was definitely on a 4.x kernel if that makes any difference.

What am I missing here?


Thank you,
S
