[SOLVED] Audio issues in Arch

ultimatr · 2021-03-20 15:51:39

Hello,

I recently installed Arch on my Desktop PC which has a DisplayPort connection to my monitor, where my monitor connects to my studio monitor speakers. The display port is plugged directly into my NVIDIA Geforce GTX 1660 Ti.

Running speaker-test I get a playback error:

speaker-test 1.2.4

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

I verified I have alsa-utils installed and ran alsamixer and unmuted all channels on all devices.

I also tried installing asoundconf,

[will@arch ~]$ asoundconf list
Names of available sound cards:
PCH
NVidia
Device

Then I set my default device to my preferred (NVidia)

asoundconf set-default-card NVidia

I run speaker-test and I get the same error:

[will@arch ~]$ speaker-test

speaker-test 1.2.4

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory

How do I fix this?

Please use code rather than quote tags for outputs.

asoundconf tends to create broken configuration . Remove the config it generated then actually check which devices are available with

aplay -l

then follow https://wiki.archlinux.org/index.php/Ad … sound_card to change the actual devices you are using. HDMI cards are often on a different device rather than 0 so your config would look something like, if we picked the first option in the link I posted

defaults.pcm.!card Nvidia
defaults.pcm.device 3 #or 7 or 9 depending on which the driving device is.

You can test this without changing the configuration directly by using the -D option of speaker test like

speaker-test -Dhw:1,3 -c2

the -c2 here is important because HDMI devices often have issues with mono streams.

Take a look here [SOLVED] Audio not available in GNOME, this resolve the problem for me.

I removed asoundconf and its configs.

It looks like my NVidia device is card 2.

From the wiki and what you wrote, I edited my /etc/asound.conf

[will@arch ~]$ sudo cat /etc/asound.conf
defaults.pcm.card 2
defaults.pcm.!card NVidia
defaults.ctl.card 2

Still no success on sudo speaker-test -c2, nor sudo speaker-test -Dhw:2 -c2

speaker-test 1.2.4

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave

EDIT:

Adding

defaults.pcm.device 7

to my /etc/asound.conf made the speaker-test start playing, however, only out of my left speaker.

You didn't quite do what I wrote. You can leave defaults.pcm.!card Nvidia but you need to figure out the correct device for defaults.pcm.device where your choices are one of 3,7,8,9,10,11,12 that'll be a bit of trial and error with speaker test or parsing /proc/asound/NVidia/eld* to figure out which device actually has a monitor on it

Edit: Glad to hear, how did you invoke the speaker-test? If you do not add a -c2 you are only testing a mono channel.

Invoked the speaker-test with -c2 and sudo because before it seemed there was an I/O error.

sudo speaker-test -c2

Still only hearing the left channel through speaker-test.

Looked at /proc/asound/NVidia/eld* and found where monitor_present was 1.

cat /proc/asound/NVidia/eld#0.4
monitor_present		1
eld_valid		1
monitor_name		ED323QUR A

sad0_rates		[0xe0] 32000 44100 48000

EDIT: Right channel working. Just a loose cable connecting to my monitor.

Thank you, V1del!

Okay, reopening this thread because the problem came back after I formatted and reinstalled Arch.

/etc/asound.conf

defaults.pcm.card 2
defaults.!card NVidia
defaults.pcm.device 7
defaults.ctl.card 2

aplay -l

Actually the alsamixer just keeps muting my shit every time I boot. Goddamn it.

V1del · 2021-03-21 02:53:55

run

sudo alsactl store

after unmuting the relevant control, that will store the volume settings for the next boot.

I rebooted another time and my NVidia card switched from card 2 to card 1. This is possibly due to my other devices alsa is detecting like my mic and motherboard audio out/in.
I stored my settings in alsactl.

Set my /etc/asound.conf to

defaults.pcm.!card NVidia
defaults.ctl.!card NVidia
defaults.pcm.device 7

Hopefully that fixes this issue.
