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 !
