No sound in notebook


I bought a used notebook and have no sound in it.

Mind you, I have checked everything I could. The output/window in alsamixer looks just fine. The sound card is correctly detected and I can tweak and adjust all controls. I also tried using a headphone, but that produces no sound either.

There is a small catch in my situation: the notebook came with Windows, which obviously enough, was removed and replaced with Linux immediately, and I forgot to check if sound was working in Windows.

However, I bought this machine from a store that specializes in refurbishing old notebooks and reselling them with a warranty. So it is possible that the sound card is defective, but I doubt it. The person who sold it to me assured me that everything was in working order and promised me to fix any problem that might come up within six months. I doubt they would have overlooked sound. Also, this purchase took place in another city, I can't afford to go back there to take care of this and I am sure they won't be too happy when they find that I replaced Windows with Linux. I definitely want to work with the theory that the sound card is fine and it's not working because... Linux.

I have removed Pulse Audio because I hate it, but I already had no sound before I removed it. I have ALSA and JACK2. What else can I do to troubleshoot this situation?

Verbal descriptions don't provide the definitive details needed to gauge what is wrong. The use of the alsa-info.sh diagnostic script is recommended - it can upload comprehensive ALSA/hardware information to an online server, and provide a link to it for others to review...
https://wiki.ubuntu.com/Audio/AlsaInfo

The speaker-test utility is good for testing audio hardware
https://www.systutorials.com/docs/li...-speaker-test/


A simple test to see if your sound works from a terminal...
Code:
speaker-test -Dplug:front -c2 -l5 -twav
If that test produces errors, try this simple test instead
Code:
speaker-test -c2 -l5 -twav
Any sound evident?

I dislike jack.

Usually on gentoo for many many years. pulseaudio + alsa. No jack-audio-connection kit.

open alsamixer

unmute anything in pulseaudio
change to your hardware
unmute anything

most guys forget to unmute pulseaudio or the hardware. Alsamixer is very bad designed in my point of view.

for myself on 3 different notebooks pulsaudio worked in the past 4 years on linux mint and gentoo.

Suggestion:

Boot up some livecd, no idea? Linux mint, knoppix? whatever, and test the sound. some card games come with some sound. e.g. pysol

and plesae try at least 4-5 different live-cds from different distros.
8 years ago pclinuxos was very awesome. knoppix is the same. than was there a linuxgamecd.

HI:

I'm not a sound expert but I have a few questions.
Does your sound card have a Realtek chipset?

If so look here:
https://wiki.debian.org/ALSA#Alternative_Method

https://wiki.debian.org/ALSA

If not what sound card do you have?
Run aplay -l to find out.

More links that may help.

https://wiki.debian.org/SoundConfiguration

Are the columns in alsamixer muted? <mm> means muted <00> is not muted.
