Sound stops after a couple seconds. Audio device disappears and reappears. Pulseaudio SIGABRT. Intel i7-10510U

Dear All,

I am having trouble with the audio on a lenovo e14 with i7-10510u. I can’t reproduce any media, opening youtube videos gives me: “Audio renderer error. Please restart your computer.” after a couple seconds. I was facing problem with an USB-C dock from lenovo and got it fixed through a kernel patch, unrelated to audio, I even tried booting an older, LTS kernel (5.4.58-1) to see whether it improved things, but no success. I tested on Ubuntu through live usb with 5.4 kernel and it works normally, but I would really like to keep Manjaro.

If I click the volume button a few times I can only hear the first ones, so it is the same behavior as youtube: audio stops working after a couple seconds, shortly after this, the popup for audio device is shown at the center of screen

Dmesg shows an abort signal for pulseaudio:
[ 4237.956842] audit: type=1701 audit(1598371072.930:243): auid=1000 uid=1000 gid=1000 ses=3 subj==unconfined pid=12190 comm=“pulseaudio” exe="/usr/b

Any help will be greatly appreciated, thanks!

This could be a solution/workaround:

I managed to install pulseaudio-git through the terminal, but upon booting with it I had no sound devices available. Then I tried reverting to pulseaudio13 and following up with the configuration from the link, but it failed just as before, after a couple seconds there is an audio device pop-up and the audio stops.

What puzzles me is that audio works normally in Ubuntu.

Would be interesting if there can be something found in the source of ubuntu. Maybe there is a special patch or script?

Could you provide more information?

For example: sudo inxi -MAxxxa

and alsa-info.sh would be useful as well.

My idea about it is now, that the autoprobing of the HDA Intel driver was wrong and you need to set it manually.

Could you try to downgrade pulseaudio? Maybe there is a problem?

sudo pacman install downgrade
export DOWNGRADE_FROM_ALA=1
downgrade pulse

choose 12.99.3

I will try that later, but meanwhile, I figured the alsa info from ubuntu, where audio works, would also be useful. It is available at:
http://alsa-project.org/db/?f=dfbe2f57948ce0cdcc70fd94f50285e4a75635f6
The differences from usb_audio are because I had the dock connected in Manjaro and disconnected in Ubuntu, as I haven’t patched Ubuntu’s kernel for a dock bug, but the issue occurs in Manjaro even with the dock disconnected in an unpatched kernel.
Oh, and I also checked the pulseaudio version for ubuntu:

ubuntu@ubuntu:~$ pulseaudio --version
pulseaudio 11.1

Unfortunately that didn’t work, I tried both 12.99.3 and 12.2, both still present the same problem.

I ended up opening an issue at pulseaudio:

sorry for the link, it seems that the forum is weird, I could post links yesterday, but now I can’t.

I was thinking, maybe I should open a bug report on Manjaro itself, as the issue seems to be isolated to this distro. Anyone could give me the directions to it?

an update: I tried Manjaro live XFCE and the sound worked flawlessly. Issue seems isolated to KDE.
