ALSA lib confmisc.c:768:(parse_card) cannot find card '0'

[spyrospph]

Hi,

Using all images that you have provided I get the following error:

  Test 1 - Desktop
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'

ALSA lib conf.c:4771:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2266:(snd_pcm_open_noupdate) Unknown PCM default

My configuration is:

1) DockerFile:

FROM cypress/base:10
RUN npm install --save-dev cypress

2) docker run command:

docker run -it -v=mye2e:mye2e -w="mye2e" <container name> /node_modules/cypress/bin/cypress run

Is there anything we need to do to surpass this problem?

[spyrospph]

Just a follow up on what i have seen.

this happens with the electron browser on the base images. It does not happen on the chrome image (cypress/browsers:chrome67) using the chrome browser.

Also needs ipc: host on your docker-compose file

[aldarund]

Same situation. Happens with electron

[kschingiz]

Any news here? How to solve this issue? What if this is happening in CI and I need electron browser that's the only supported browser can run headless?

[aldarund]

@kschingiz despite this error happens tests are going fine

[kschingiz]

@aldarund no, my tests was broken when this error was thrown.

I fixed this bug, electron browser required sound cards, but my virtual server doesn't have any physical sound card. If you see this bug happening, that means you have not setup ALSA in your OS. In case if you are using virtual linux server, that doesn't have any physical sound card, you should install dummy sound card. Here are instructions: https://www.alsa-project.org/main/index.php/Matrix:Module-dummy

And don't forget to add "jenkins" user to the "audio" group, in case if jenkins doesn't see any sound cards.

[aldarund]

For me tests not broken although this error printed on every test. although this solution will work in some cases, its wont work for all e.g. in hosted CI, since u cant add sound card in hosted CI

[aldarund]

@bahmutov is there a better way to workaround this?

[bahmutov]

Which website requires sound to work? We never hit this problem before, so would be interesting to see this.

[aldarund]

@bahmutov i dont use any of sound myself on my website but its still throwing this error. Maybe freshchat widget do smthing.. For example it happens on https://beta.tenantreport.net/auth/login ( when deployed on CI )

[12:21:05] Rendering url /auth/login/ ALSA lib confmisc.c:767:(parse_card) cannot find card '0' ...

[bahmutov]

@aldarund can you see why it would pass on our CI machines (https://github.com/cypress-io/cypress-test-tiny/pull/32) and not in your docker container?

[aldarund]

@bahmutov for me it pass too unlike the someone who said it crash completely. But it also print that error in output. https://i.imgur.com/GsUtIaz.png

[aldarund]

Maybe your ci have an audio device configured?

[aldarund]

Ye, it probably goes from freshchat since its loading https://wchat.freshchat.com/assets/audio/notif.mp3 But its loaded async so another option might be that during that short test it just dont have time to load

[bahmutov]

Excellent @aldarund I added cy.wait(10000) and see the error messages (although it does not fail the build on Circle) in https://circleci.com/gh/cypress-io/cypress-test-tiny/1037

and I see same errors on Codeship (also, not failing the build)

[aldarund]

Ye, exactly, for me it also just spam this error into console on wercker ci but build still successful and tests passed.

[bahmutov]

hmm, I wonder if there is a way to disable the sound completely to remove these errors, ughhh

[Francismb]

Getting this error on my local machine in WSL. It, however, does not prevent the tests from running, it just clogs up the logs.

[calaldees]

I was able to suppress these warnings by configuring ALSA to use a pcm.null destination. (This may not be ideal for all use cases because my assumption is that videos recorded with electron will not record with audio.)

example asound.conf

pcm.!default {
    type plug
    slave.pcm "null"
}

example .dockerfile

FROM cypress/browsers

COPY asound.conf /etc/asound.conf

[vicusbass]

@calaldees weirdly enough, I am still getting the warning ONCE using your trick :)

[vlodko]

is there a way to disable sound for cypress tests?

[wb-08]

You need to install pulseaudio or pulseaudio-alsa and run your container like docker run \ -v /run/user/1000/pulse/native:/run/user/1000/pulse/native \ -e PULSE_SERVER=unix:/run/user/1000/pulse/native \ -u 1000:1000 \

[GuillaumeBAECHLER]

Not sure if this is a good solution but here is what I just experienced:

Using docker image cypress/included:11.2.0 in jenkins. Running Electron in headless. I got the ALSA lib confmisc.c:768:(parse_card) cannot find card '0' error and also got libva error.

Tried to apply this comment workaround but then ALSA was complaining about the configuration file being old or corrupted. libva error was still there.

Took a look at Xvfb and tried to start X11 server before running cypress even if nothing is running in parallel.

Adding these commands before running cypress is what removed both libva and ALSA errors for me.

Xvfb :99 &
export DISPLAY=:99;

Hope this can help. If you think this is not a good solution I would be happy to know 😅

This is an old issue for versions which are no longer supported.

If the issue is still occurring, please open a new issue with details.
