Sound stops after a while

[george1792]

Hello,

I am in unhappy position because my Lenovo thinkpad T510 , stops sound after a while from speakers, when using headphones it works correctly. I have searched and apply some of the online ubuntu solutions but nothing works. I run Ubuntu20.04.4LTS / Kernel 5.13.0-41-genneric. Let me know if u need some more info.

Thank you

I would appreciate if anyone could help me .

How are you connecting the speakers , via a dock for the laptop , the headphone output or are they built in?

[george1792]

I use the laptops built in speakers, when I plug in the headphones is working properly with no stops.

When it stops, run:

dmesg | tail

What is the output please?

I"m having similar sound issues. I'm not a sophistated terminal-wizard so I can't offer those kind of solution possibilities. As for me, I'm trying the below suggestion that I read yesterday in Distrowatch (see last line of quote) to see if this applies. I'll let you know if it helps. Maybe it might help you.

"Some people running the new 22.04 version of Ubuntu have reported a problem with the way the distribution now handles low memory situations. In the past, Ubuntu (like most Linux distributions) would allow processes to consume as much memory as they wanted. This would sometimes result in applications gobbling up memory and then swap space, resulting in more disk access and poor performance. Ubuntu now employs the systemd out of memory (OOM) service which will kill processes when memory gets close to full. Somepeople are feeling the side effects of this change, specifically finding applications (and their related processes) are suddenly terminating without warning. "Ubuntu 22.04 comes with the systemd-oomd service enabled by default, which has been 'helpfully' killing my IDE and/or terminals whenever I try to compile an application using an abundance of threads/memory. What is the right way to either turn this off, or configure the service to not shoot random processes in the face while I'm using them?" The new behaviour can be turned off using the command "sudo systemctl disable --now systemd-oomd" and a bug has been filed for this issue."

With pulse audio, sometimes the program crashes. Restarting it often make it work again. PulseAudio is brought to us by the same people behind SystemD, FYI.

The commands to restart it are

/usr/bin/pulseaudio -k
/usr/bin/pulseaudio -D

I've made many assumptions which may not be true in the situation on your system.
