[SOLVED] No audio output using pulseaudio

I wonder whether anyone can advise an audio noob...

* I have a new Arch installation, running just Openbox as the WM - there is no desktop environment. 

* My machine uses speakers embedded in the monitor, so I believe the video card doubles up as a sound card and the speakers are fed via the HDMI video connection.  Using the controls on the monitor, the speaker volume is set at 100% and they are unmuted.  I know that the speakers work, because I can use them if I boot into Windows. 

* I have an NVidia GeForce GTX 1650 video card, also known as a TU117. 

* I have installed the pulseaudio and pulseaudio-alsa packages. 

* I can get no audio output, either from Firefox (YouTube videos) or by using 'speaker-test -c2' (obtained by installing the alsa-utils package). 

* I have:

$ cat /proc/asound/cards
 0 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xf7080000 irq 59
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf7400000 irq 61

I guess one is the video card and the other an audio output on the motherboard. 

* I also have:

$ pactl list sinks
Sink #2
	State: SUSPENDED
	Name: alsa_output.pci-0000_29_00.1.hdmi-stereo
	Description: HDA NVidia Digital Stereo (HDMI)

		alsa.subdevice_name = "subdevice #0"
		alsa.device = "3"
		alsa.card = "0"
		alsa.card_name = "HDA NVidia"
		alsa.long_card_name = "HDA NVidia at 0xf7080000 irq 59"

		device.bus_path = "pci-0000:29:00.1"
		sysfs.path = "/devices/pci0000:00/0000:00:03.1/0000:29:00.1/sound/card0"
		device.bus = "pci"
		device.vendor.id = "10de"
		device.vendor.name = "NVIDIA Corporation"
		device.product.id = "10fa"
		device.string = "hdmi:0"
		device.buffering.buffer_size = "352768"
		device.buffering.fragment_size = "176384"
		device.access_mode = "mmap+timer"
		device.profile.name = "hdmi-stereo"
		device.profile.description = "Digital Stereo (HDMI)"

		alsa.components = "HDA:10de0094,10de1f82,00100100"
		module-udev-detect.discovered = "1"
		device.icon_name = "audio-card-pci"
	Ports:
		hdmi-output-0: HDMI / DisplayPort (priority: 5900, available)
	Active Port: hdmi-output-0
	Formats:
		pcm

...so the sink appears to be suspended. 

* If I run:

$ pactl suspend-sink alsa_output.pci-0000_29_00.1.hdmi-stereo false

.. the command has an exit code of 0 and it produces no output, but the sink still shows as suspended (and there is still no audio output). 

* I have tried following the advice on the pulseaudio troubleshooting page of deleting my ~/.config/pulse directory, but this seems to make no difference.  (I don't have the files ~/.pulse and ~/.pulse-cookie that are mentioned in the same place on that page.) 

* I've tried Googling this, to no avail.  The nearest I've seen is a suggestion to disable suspend-on-idle in /etc/pulse/default.pa.  I tried this, and it made no difference. 

Can anyone suggest what I should investigate next?  Knowing nothing about audio, I'm pretty stumped.

Re: [SOLVED] No audio output using pulseaudio

Try to install pavucontrol. Launch a video on Youtube, start pavucontrol and see the browser which output sink is using. Try to switch between available sinks, I think you should use HDMI.

Re: [SOLVED] No audio output using pulseaudio

@digitalone that's the reason I request these outputs for.

Judging from those everything on the pulse chain does indeed seem correct, baring as misdetection and you actually having to use a HDMI port that's marked as unavailable, the hdmi port has state running and firefox is pushing audio data out.

Do you see any error messages in dmesg or so?  Did you double check compare in windows that it indeed uses the first "0" display port for pushing audio data? While we're on the topic is fast boot disabled ?

If have a faint memory that there used to be HDMI audio bugs in recent times with certain nvidia/kernel combinations but to my knowledge these should be fixed in the versions we currently have in the repos.

Thanks @digitalone.  I installed pavucontrol, and everything looked as I would have expected - my HDMI output was 'available', and, playing a YouTube video showed the volume meter going up and down.

Thanks @V1del.  Not sure what to look for in dmesg.  After trawling through it, the following three areas look relevant:

I wonder whether the nouveau message 'DRM: failed to create kernel channel, -22' could be relevant?  (Googling suggests not.)  I also wonder whether a lack of sound support is a "feature" of the nouveau driver, and that I would get on better with the proprietary one? 

Within my Windows installation, I checked the fast boot setting, and it was enabled.  I have now disabled it, but this has not cured this sound problem. 

Windows shows three sound sources:
- Speakers / 4 - Realtek(R) Audio / Not plugged in
- NVIDIA Output / NVIDIA High Definition Audio / Not plugged in
- PL2483H / NVIDIA High Definition Audio / Default device
The 'PL2483H' is actually the model number of my iiyama monitor.  Both the 'NVIDIA Output' and the 'PL2483H' show in their properties that they use 'NVIDIA High Definition Audio' as their controller.  Its properties in turn show it has a location of 'Location 0 (Internal High Definition Audio Bus)', which I guess matches up with what you describe as 'the first "0" display port'.

Re: [SOLVED] No audio output using pulseaudio

Yes I am slightly amazed that nouveau might've progressed far enough that someone can use it on a Turing based card and the only thing they notice to be off to be audio support (unless you are on a laptop and actually running on intel, though evidence so far seems to point to that not to be the case).

I'd definitely suggest you try the proprietary drivers.

No, I'm on a desktop PC with an AMD CPU. 

I revisited https://nouveau.freedesktop.org/wiki/FeatureMatrix/, and I see now that it includes 'HDMI Audio' in its list of 'TODO' features for the Turing/NV160 series cards.  I should have taken more notice of that the first time I looked at it...

I've removed the nouveau package and installed the nvidia one.  Sound now seems to be working fine, so problem solved - thanks for pointing me in the right direction.

Re: [SOLVED] No audio output using pulseaudio

Hello,

I am facing a similar problem. I check everything listed in the post but alsamixer seems to be different. I can't change the volume using alsamixer.

Re: [SOLVED] No audio output using pulseaudio

Please don't necrobump  a year old solved thread. Since audio issues can have a variety of causes it's almost never "same" issue.

Please open a new thread including the outputs from my post in #2  and how you intend to use the audio device (i.e. do you actually want to use HDMI or do you intend to use a different card?)

Closing this old thread.
