Audio not working and no sign of problem/error

I don't hear any sound from any application, however speaker-test runs fine, without any error.

[jay@alienware ~]$ speaker-test 

speaker-test 1.1.2

Re: Audio not working and no sign of problem/error

Do you have pulseaudio installed?
If yes, do you have pulseaudio-alsa installed?

Re: Audio not working and no sign of problem/error

I tried the following two things

https://wiki.archlinux.org/index.php/Pu … dio_device
everything is at level 00,

and
https://wiki.archlinux.org/index.php/Ad … ter_reboot
I got this

[jay@alienware ~]$ alsactl restore
alsactl: state_lock:125: file /var/lib/alsa/asound.state lock error: File exists
alsactl: load_state:1683: Cannot open /var/lib/alsa/asound.state for reading: File exists
alsactl: sysfs_init:48: sysfs path '/sys' is invalid

Found hardware: "HDA-Intel" "Creative CA0132" "HDA:11020011,10280708,00100918 HDA:80862809,80860101,00100000" "0x1028" "0x0708"
Hardware is initialized using a generic method


I tried to alsactl restore with sudo too, it doesn't gave any error yet no sound.

Re: Audio not working and no sign of problem/error

alsactl needs to be run as root , not as user.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

yes it is running, but don't know why there are two such processes

Re: Audio not working and no sign of problem/error

Do you get sound from that speaker-test? Or does it just run and no sound?

Is this a Creative Soundcore 3D or similar? They don't have any official drivers, there's somewhat of a chance that your headset port might work, but for cases where it works the pin layout is hardcoded for specific hardware, if your hardware is not in that list you are somewhat screwed. One thing you can try is trying to get a correct setup with hdajackretask and/or loading the snd_hda_intel module with the position_fix=1 parameter with an entry in modprobe.d

If I'm misinterpreting and you actually get sound from the speaker-test post 

pacmd list-cards
pacmd list-sinks
pacmd list-sink-inputs #While playing something

(Side-info: You should run fuser commands as root/with sudo, otherwise you will only find applications where your own user has access, which is mostly useless in debugging problems that could arise from multiple users accessing a soundcard)

Re: Audio not working and no sign of problem/error

no I am not getting sound when doing speaker-test but it also doesn't show any error.

yes it is Creative soundcore3d, this is spec from dell site

Creative Sound Core3D-EX Audio with Creative Soundblaster Pro Studio Software
2.0 Speaker configuration
Audio Powered by Klipsch®
7.1 Digtial Audio out using HDMI out connection

that 3.5mm jack port(headphones) is not working too, but that is the problem since installation, inbuilt speakers were working, but they accidentally stopped few days ago.

Re: Audio not working and no sign of problem/error

Have you installed pavucontrol  ?  It is a handy tool that, unlike many GUIs, does a good job of being discoverable and intuitive.  That tool has several controls you can quickly tweak to try to get sound.  More importantly, it will show you all the programs that are trying to produce sound, show you an individual volume control for each program, and will show an audio level indicator for each audio source.

Fire that program up and ensure your sound generating programs are represented, and that their audio meters are "bouncing".  Once that is working, if there is still no audio, there are similar controls for the back end.

Re: Audio not working and no sign of problem/error

Just from pulse's side, you are currently playing to the SPDIF output which is unlikely to be what you want, switch that 

pacmd set-card-profile alsa_card.pci-0000_00_1f.3 output:analog-stereo+input:analog-stereo

Further than that I second the notion on getting familiar with pavucontrol.

Re: Audio not working and no sign of problem/error

Thanks V1del switching with

pacmd set-card-profile alsa_card.pci-0000_00_1f.3 output:analog-stereo+input:analog-stereo

worked.
what is the difference between analog-stereo and SPDIF. I read about SPDIF on wikipedia but it is still not clear.
Still head-phones are not working, after plugging it sound still comes from internal speaker.

Re: Audio not working and no sign of problem/error

Headphones not working is likely a limitation of the drivers for this card. SPDIF is for digital output, often for external audio appliances (big surround systems for example) that want the audio in digital format and convert them to analog themselves. But the speakers in your laptop are hooked to the card with analog, so you want to have the profile set to analog.

If the thread is solved for you, don^t forget to prepend the title with [SOLVED] or similar.

Re: Audio not working and no sign of problem/error

it stopped working again, even though sink is analog-stereo (instead of SPIF).
haven't updated the system.

Re: Audio not working and no sign of problem/error

That looks correct, do you get a DSP initialization failure or similar in dmesg? Another thing, since the stream starts corked, do you have some kind of recording software open that might cork your streams? What does 

pacmd list-sources
pacmd list-source-outputs

give?

Re: Audio not working and no sign of problem/error

check your dmesg next time this happens, there's a chance that the driver fails to load the DSP module and it's somewhat random when/if this happens and might be mitigated by rebooting or similar. As mentioned this driver is highly finicky and unless creative starts to help out I don't see this changing anytime soon.

Re: Audio not working and no sign of problem/error

Hi all,

I didn't want to open a new topic with the same problem and since it appears the original problem was solved, I thought maybe I can hijack this one.
Today I lost all HDMI sound output from my PC after an update. Normally I get sound from NVidia HDMI Audio to my monitor's speakers. It used to work.
I feel like it is something about the configuration but I am not expert enough to understand the details.

I had pulseaudo-equalizer installed and thought that may be the source of the problem and uninstalled it.
Nothing changed. I have pavucontrol installed. When I play a video in firefox, pavucontrol shows a "cubebutils" stream
and the signal bar is acting like normal. However I hear no sound.

When I do left/right speaker test from the sound control dialog, I hear nothing.

When I plug speakers to the analog output, and switch the sound output from HDMI to analog, I can hear sound from
the speakers. When I switch back to HDMI, I get no sound at all without any warnings or errors.
Oh, and the monitor's sound levels are at maximum and nothing is muted smile

Here are some possibly helpful outputs:

Re: Audio not working and no sign of problem/error

Please don't hijack threads, your problem has nothing to do with the OPs problem, and make sure to use code tags instead of quote tags.when you open a new topic. Post the information I've asked for here as well.
