<Solved>LM 20.2 Getting Sound out of onboard HDMI

[solarbear]

I want to use my motherboard HDMI to send signal to TV, but the sound isn't working although the video signal is working good. I have sound through my Nvidia card HDMI , but it is signaling to my 1920x1080. the motherboard is Intel 6 Series/C200 Series Family High Definition Audio

here is my inxi:

Hi solarbear,

Let's get a look at your sound setup with this command:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

The last line of output will have a URL pointing to the info. Pasting that URL is all I need.

It's a bit overkill for this, but that one prevents me from needing to keep asking for new outputs.

[solarbear]

ok, i think it executed properly..

[MrEen]

Well, nuts!

I'm not seeing a second HDMI option that I was expecting to see:

Card #1
Name: alsa_card.pci-0000_00_1b.0
Driver: module-alsa-card.c
Owner Module: 8
Properties:
alsa.card = "0"
alsa.card_name = "HDA Intel PCH"
alsa.long_card_name = "HDA Intel PCH at 0xfb300000 irq 36"
alsa.driver_name = "snd_hda_intel"
device.bus_path = "pci-0000:00:1b.0"
sysfs.path = "/devices/pci0000:00/0000:00:1b.0/sound/card0"
device.bus = "pci"
device.vendor.id = "8086"
device.vendor.name = "Intel Corporation"
device.product.id = "1c20"
device.product.name = "6 Series/C200 Series Chipset Family High Definition Audio Controller"
device.form_factor = "internal"
device.string = "0"
device.description = "Built-in Audio"
module-udev-detect.discovered = "1"
device.icon_name = "audio-card-pci"
Profiles:
input:analog-stereo: Analog Stereo Input (sinks: 0, sources: 1, priority: 65, available: no)
output:analog-stereo: Analog Stereo Output (sinks: 1, sources: 0, priority: 6500, available: no)
output:analog-stereo+input:analog-stereo: Analog Stereo Duplex (sinks: 1, sources: 1, priority: 6565, available: no)
off: Off (sinks: 0, sources: 0, priority: 0, available: yes)
Active Profile: off

Try looking in your BIOS to see if there's anything audio related you can try changing there.

I doubt this will help, but let's also look for errors with this command:

Code: Select all

dmesg | grep -C1 -E 'ALSA|HDA|sof|HDMI|snd[_-]|sound|hda.codec|hda.intel'

[solarbear]

apologies,

My motherboard HDMI takes precedence during boot and sends the signal to the TV first for post screen and then grub also so i unplugged it, but i also have a 26 inch monitor with built in speakers so i will plug the mobo HDMI into that for the reading because the TV is busy right now...brb

here is the updated inxi with the mobo hdmi plugged in

I will look in BIOS for audio settings, but this being a Dell PC, the options are kind of limited, although, the integrated video option is a sweet deal, combining mobo video outs with the video card.


i just did a audio check, low and behold, the mobo hdmi is sending sound to my 26 inch monitor, it wasn't doing that with the TV, it just read dummy output

[MrEen]

I know this will sound silly, but did you check the TV's volume when you were plugged into that?

[solarbear]

That is something that actually does vary like wild... different signals , different volumes. I have to adjust the TV volume all the time with the different inputs (DVD player, airwaves, streaming, etc)

When i looked in sound properties, i saw dummy output so i knew the signal wasn't complete.

[MrEen]

Okay, the Dummy Output was probably because you turned of the built-in sound card, and the Nvidia card for some reason wasn't working audio-wise.

The best thing I have at the moment is to run pulseaudio -k in the terminal the next time that happens and see if that kicks it into gear.

[solarbear]

ok, i will keep that in mind, thanks for the assist, this topic can be tagged as solved

[MrEen]

You're welcome.
