[SOLVED]: alsa and hda-nvidia guidance

[Member techore]

I am seeking guidance on how to use alsa without pulseaudio on a computer using a discrete NVidia GPU.

Details:

1. Disabled the system board audio in BIOS
2. nVidia GPU installed using ddm-mx -i nvidia
3. alsa-set-sound-card reports only one card detected, “NVidia: HDA-Intel – HDA NVidia
4. alsamixer displays the HDA NVidia device and five(?) spdif (MM); depressing “m” results with (00)
5. EDIT: testing applications including aplay, qutebrowser, and firefox-esr result with no sound
6. Audio works after installing pulseaudio, pulseaudio-utils, and pavucontrol with no further changes

Both antix-core and antix-base exhibit the same symptoms on the computer.

My feeling is I have failed to configure alsa correctly, but that is a guess.

Hi techore, very quiet here, probably no helper has a similar setup
in usage.

I do have NVidia graphics (back at last) but use an audigy soundcard,
bit shy of experimenting too much, was unable to connect to NVidia sound
in a quick check..

Best suggestion I can make is to start with a full antix version and get
sound working with that than transfer knowledge, or slim down the full version,
something I have found much easier than building from base.

If you can get and set sound with the controll center application it should
enable easy transfer of sound related settings such as alsarc etc.

I gave a antix-base a go but I didn’t give antix-full a try. Simple enough to download, install on USB, and test. An excellent suggestion. *fingerscrossed*

Hello techore.

6. Audio works after installing pulseaudio, pulseaudio-utils, and pavucontrol with no further changes

Some people are getting the audio following this thread Pipewire to manage audio in antiX 21.
I don’t own two audio cards like you, but I got some good results with PipeWire, but in some specific cases I needed to install PulseAudio, as the computer got very slow after installing PulseAudio, I disabled it from antiX startup 21. When I need PulseAudio, I click on the menu PulseAudio Activator and Deactivator

Olá techore.

6. Audio works after installing pulseaudio, pulseaudio-utils, and pavucontrol with no further changes

Algumas pessoas estão obtendo o áudio seguindo este tópico Pipewire to manage audio in antiX 21.
Eu não possuo duas placas de áudio como você, mas consegui alguns bons resultados com o PipeWire, mas em alguns casos específicos, eu precisei instalar o PulseAudio, como o computador ficou muito lento depois da instalação do PulseAudio, eu o desativei da inicialização do antiX 21. Quando eu preciso do PulseAudio, clico no menu Ativador e Desativador do PulseAudio

It chaps my hide that I don’t have sufficient knowledge to get alsa working for the descrete GPU. Works fine on my other four boxes using built-in system board audio chips. I am determined to get alsa working, however, pipewire would be a acceptable alternative while I figure it out.

Thank you for the suggestion.

Hi techore, maybe some help in

https://bbs.archlinux.org/viewtopic.php?id=186597

Hard to understand how setting one card can push the default to the GPU
but worth a try.

Agreed. Doesn’t make sense. I’ll read it again and check my assumptions.

Thank you, @Moddit.

After reading it again, my take away is the poster is dealing with two sound devices and wants to use the second device as the default. Interesting reading and “emeres” knows his stuff.

I will keep digging and appreciate the reference.

Hello,

On my desktop with antiX Full, I use the sound of the motherboard to connect my 2.1 stereo speakers with subwoofer in addition (it’s Logitech). I don’t use the sound provided by my NVIDIA GTX960 graphics card on my 2 monitors which also have speakers.
I don’t think it’s interesting to disable the sound on a motherboard from the bios. I have no problem with Alsa.

Best regards,
Wallon

@wallon, not suggesting folks not use onboard audio chips and, yes, they are, generally, easy to setup with alsa.

The computer with the audio issue is a home theater system, so it makes sense to send the two-channel digital audio using the hdmi to the receiver in “direct” mode. A decade ago, I used good quality audio boards with optical out to serve the same purpose. An option, I would prefer to avoid ($$$).

Hi Techore, the posts do make sense to me although seem confusing.
You also have 2 sound devices.

 cat /proc/asound/cards
 0 [NVidia         ]: HDA-Intel - HDA NVidia

I have 3. Intel is off in BIOS but strangely still active. Audigy set to default.
cat /proc/asound/cards

                      HDA Intel PCH at 0xf7310000 irq 34

Maybe I can find time to try and get sound from my NVidia card over the weekend, might find some
clues to help with your issue.

@wallon, techore wants sound through his NVidia card.
There are many reasons for wanting to use a discrete card for sound.

Gamers or those working with video will want sound in synch with scenes and thus prefer
to use the Graphics card. I prefer my audigy card as the sound quality is vastly better
than onboard. But if for any reason a lot of frames drop in video sound is out of synch..

@ techore wondering if aplay -L will provide any clues.

Maybe worth trying, if you have not done so already, you will
need to insert correct device.

.asoundrc-device addition (my output device is hw:0,3):

pcm.stereo {
type plug
slave {
pcm { type hw card 0 device 3 subdevice 0 }
channels 2
}
}

I got it! and thank you, @Moddit.

Your response set me on a line of discovery that was fruitful.

Ultimately, I just needed to:

1. Set the default card, *device*, and control in /etc/asound.conf
2. Unmute the alsa device s/pdif1 using ‘alsamixer’
3. Save to persist across reboots using ‘alsactl store’ which updates /var/lib/alsa/asound.state

Step one may not stick on package updates and steps 2 and 3 are just awkward. However, it works!

head -15 /etc/asound.conf

Results:

# v4.0
# Requires alsa-utils libasound2-plugin-equal

# ***** Defaults *******************************************************

# Audio card/chip and device to use and control
# In most cases these settings should remain commented (#)
# When commented, card and device 0 are usually automatically selected
# When uncommented, the item corresponding to the number is selected
defaults.pcm.card 0
defaults.pcm.device 7
defaults.ctl.card 0

Some of the more useful references I found.

Good news Techore,
I find every layer on top of alsa makes sound
more murky and artificial, with a good audio setup that is
important.
Enjoy :-).

I think the setup problem may not have happened with a full version
of antiX as the control center tools generaly do the settings
reliably on a user to user basis.

Maybe worthwhile exploring the antiX scripts. The gui is only icing on
the cake so with little change they should be usable in the terminal
on more minimal systems.

My system wide default card setting with etc/asound.conf is
empty/commented out.
Asound.rc does the job for me as an individual user configuration.
Regarding asound not always sticking on updates, set it read only
which should help.

Thanks for links, especialy the first one sound from NVidia is well
written and easy to understand. Noted for future use.

Second user is for official work, endless hard to understand
forms churned out by German officials to show the masses how
powerless they are in the face of the state.
