I think I found out what's happening. When the machine boots, and the login screen is displayed The sound is not immediatly initialized and working If, when it's not yet ready, I press the cut volume/volume up/volume down It puts the sound card and/or Pulse into a state where it gets stuck...
If I wait a little after login, say 5 seconds or so The sound card finishes its initializatino thing (or Pulse, no idea) And then I have no problem with sound Not sure this is really a bug... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1894881 Title: [XPS 13 9300, Realtek ALC289, Speaker, Internal] Pulseaudio fails to detect card Status in linux package in Ubuntu: Incomplete Status in pulseaudio package in Ubuntu: New Bug description: kernel 5.4.0-47-generic #51 upgraded today to this new kernel sound is now totally broken kern.org and syslog are filling with those messages every second, in loop, with no end to it : Sep 8 19:42:34 orion kernel: [ 147.398030] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x20970500 Sep 8 19:42:35 orion kernel: [ 148.410043] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x20a70500 Sep 8 19:42:36 orion kernel: [ 149.413955] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x20b70500 Sep 8 19:42:37 orion kernel: [ 150.421890] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x201f0500 Sep 8 19:42:38 orion kernel: [ 151.453799] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x204f0015 Sep 8 19:42:39 orion kernel: [ 152.461793] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x204f0015 Sep 8 19:42:41 orion kernel: [ 153.473734] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x2043b000 Sep 8 19:42:42 orion kernel: [ 154.477653] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x20470740 Sep 8 19:42:43 orion kernel: [ 155.481576] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x204f0015 Sep 8 19:42:44 orion kernel: [ 156.489620] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x204f0015 Sep 8 19:42:45 orion kernel: [ 157.497553] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x2043b000 Sep 8 19:42:46 orion kernel: [ 158.509530] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x20470740 Sep 8 19:42:47 orion kernel: [ 159.513471] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x204f0015 Because of this, machine has become very slow and response time is awful Login into the machine, even trying to launch a simple program can take up to 30 seconds of wait before anything happens.
