Title:
[ThinkPad X1 Carbon 6th] Crackling sound with HDMI
Status in linux package in Ubuntu:
Incomplete
Status in pulseaudio package in Ubuntu:
New
Bug description:
Hello,
I have a new laptop and I cannot manage to have a clean and stable sound with
HDMI.
It happens every time I play a track on Spotify (desktop and web), sometimes
from a VLC radio or a youtube video, never from a video with VLC yet.
I'm attaching a record of what I hear when I play a track from
Spotify.
I created two reports.
One during a Spotify playing, when it is crackling and after the sound
started to crackle everywhere:
http://alsa-project.org/db/?f=4e7d724718a48179fa2f3740d5f3e634ad75def9
Another after a fresh reboot, where the sound is correct with at least
YouTube:
http://alsa-project.org/db/?f=2ec68f888bb93a0de648d48fd720f54cee644564
Just after this last report, the sound is still crackling with Spotify
and VLC radio. Not with Youtube.
A diff on theses files gives some differences I find suspect. Are
there expected ?
Do you have an idea where the problem comes from ?
Thank you for your support !
Edouard
