 Posted: Tue May 09, 2023 1:07 am Post subject: ALSA error unable to open slave |
 |
|
Hello there my fellow Gentooers!
I have been caught offguard by this random error after I ran emerge --ask --depclean to clean my system (I checked the packages before, btw)
but apparently something has managed to slip through my watch and now ALSA is broken!
whenever I try to play a file in VLC this happens:
| Code: |
ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.9/work/alsa-lib-1.2.9/src/pcm/pcm_dmix.c:999:(snd_pcm_dmix_open) unable to open slave
[0000559fc10aafd0] alsa audio output error: cannot open ALSA device "default": Arquivo ou diretório inexistente //leaving a note here, for those wondering this is the default 'No such file or directory' error
|
and I can confirm that indeed /var/tmp/portage/media-libs doesn't exist!
Another very interesting thing to note is that the /etc/modprobe.d/alsa file is also absent.
I tried to update my use flags, my system and my kernel settings, but to no help!
what should I do  |

Try recreating /etc/modprobe.d/alsa.conf with those lines (warning it's very trimmed, I removed all the OSS part)
| Code: | # Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# sound card slots, comma separated list
options snd slots=snd-driver1 |
Replace snd-driver1 by your main soundcard driver (for onboard realtek chips/HDMI outputs it's usually snd-hda-intel ), then reload the sound driver module.
It should work unless your cleaning also removed essential alsa packages. |

Does speaker-test work, or does it error our the same way?
Also, IMHO sound should be built into the kernel as you usually want sound to work at all times.

Nope, same thing with speaker-test
| Code: |
speaker-test 1.2.9
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.9/work/alsa-lib-1.2.9/src/pcm/pcm_dmix.c:999:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,Arquivo ou diretório inexistente // No such file or directory

Are you missing any of them?
Also, post the output of:

Do you have an asound.conf or .asoundrc?

The problem seems to be here:
| Code: | | openat(AT_FDCWD, "/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK|O_CLOEXEC) = -1 ENOENT (Arquivo ou diretório inexistente) |
You seems to be missing /dev/snd/pcmC0D0p.
Judging from the output of ls -lah /dev/snd, you have SND_DYNAMIC_MINORS=Y, so I don't know what minor number /dev/snd/pcmC0D0p should have.

Your ls /dev/snd makes me believe alsa detects 4 soundcards (controlC0 to 3).
Would you mind doing cat /proc/asound/cards ? |

Assuming you use udev or something similar, a temporary fix would be to mknod the proper /dev/snd nodes.
You could try different minor number to see if anything works.

Which one do you want to use?
If it's not the nvidia card, you will probably need an asound.conf
Here is mine:
| Code: | ctl.!default {
type hw
card 2
}
pcm.!default{
type asym
playback.pcm {
type plug
slave.pcm "dmix:CARD=2,RATE=48000"
}
} |
For you, something like this will probably do:
| Code: | defaults.pcm.card x
defaults.ctl.card x |
Replace x with the right number.

Try speaker-test -c2 -Dplughw:3
It if works, you should get sound from your headphones (careful about volume).
edit : kill your webbrowser (or any app that usually output sounds) before
PS : "Generic" might be your motherboard audio device. |

that did the trick (kind of)
while i can hear rhythmbox and vlc, i cant hear firefox (even after a restart and a re-emerge)
also if possible, i'd like to know how to change to pipewire...? (my system used pipewire before the --depclean broke everything)

I can't help you with pipewire as I don't use it.
I use alsa only and apulse for mic support in librewolf.
You may have dmix disabled. Does firefox not work even if it's the only app launched?
Why do you need pipewire?

nope

The audio quality is better imo (At least it sounds better and has less delay in my DAW)

As stefan1111 suggested, putting those 2 lines | Code: | defaults.pcm.card x
defaults.ctl.card x |
in a ~/.asoundrc or /etc/asound.conf (in your case with x=3) should be enough for you to get sound playback, firefox included.
Firefox devs dropped alsa support a few years ago. It can still work on a pure alsa system, but it's a bit touchy (I think it doesn't work with anything else than 16bit 48Khz stereo output).
One solution can be to install apulse and then change your firefox shortcut to apulse firefox.
I don't agree with better audio quality through pipewire, quality should be unchanged, or worse if e.g. pipewire does a resampling, and then pass the signal to alsa which does another resampling.
Afaik, many people using their computer to record music use JACK, maybe you should read about it (but then you will need more qualified people for proper help  ). |

firefox have jack support, and it is very easy to get all the ALSA applications into the JACK graph, that with the jack alsa plugin (media-plugins/alsa-plugins).
In my system, I have an old style /etc/modprobe.d/alsa.conf file. It have worked from years on several computers with very minor changes:
| Code: | # Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
alias snd-card-0 snd-aloop
alias snd-card-1 snd-intel
alias snd-card-2 snd-intel
alias snd-card-4 snd-usb-audio
## OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
alias sound-slot-2 snd-card-2
alias sound-slot-3 snd-card-3
##
# The alsa applications will use it:
options snd-aloop index=0
# for the model option, see the output of 'lspci -s ... -n'
options snd-hda-intel index=1 model=1002:1637
options snd-hda-intel index=2 model=1022:15e3
options snd-usb-audio index=3
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
## OSS/Free portion - card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
## OSS/Free portion - card #3
alias sound-service-2-0 snd-mixer-oss
alias sound-service-2-3 snd-pcm-oss
alias sound-service-2-12 snd-pcm-oss
## OSS/Free portion - card #4
alias sound-service-3-0 snd-mixer-oss
alias sound-service-3-3 snd-pcm-oss
alias sound-service-3-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
# Set this to the correct number of cards.
options snd cards_limit=3
|
The ~/.asoundrc file look like that:
| Code: | pcm.!default {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
ctl.mixer0 {
type hw
card 0
}
|
In cadence, it is just to select the ALSA -> JACK plugin, and the real sound hardware card for the alsa input and output devices. And for native jack support with firefox and other supported software, I put the "jack" USE flag directly into /etc/portage/make.conf. |
