Please upload a complete dmesg with the kernel you updated on 19/03/2024 (dummy output).
And could you also test the latest upstream mainline kernel or ubuntu 24.04 (just put the iso to usb flash drive, boot from it and try ubuntu 24.04, no need to install). https://kernel.ubuntu.com/mainline/v6.8/ And also, it looks like a hardware issue to me. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/2051570 Title: [Vostro 3400, Cirrus Logic CS8409/CS42L42, Speaker, Internal] Underruns, dropouts or crackling sound Status in alsa-driver package in Ubuntu: New Bug description: Since the last three weeks' updates, I have encountered several challenges with the audio functionality on my system. Primarily, upon starting my laptop, the audio often fails to work, displaying "Dummy Output." To resolve this, I find myself needing to restart the laptop two or three times before the audio becomes functional. Even when the audio is working, I've noticed a recurring issue where, after playing video or audio for approximately 2-3 minutes, the sound starts crackling and buzzing. The intensity of these distortions gradually increases, resembling the static interference on a radio station with a weak signal. This issue persists even when using 3.5mm headphones, requiring the use of a USB headset or Bluetooth headphones to enjoy distortion-free audio. Furthermore, I have observed that, regardless of the Ubuntu version (ranging from 22.04 to 22.04.3), I face difficulties changing the microphone output settings when an external audio peripheral, such as a USB headset, 3.5mm headphones, or Bluetooth headphones, is connected. The OS appears to exclusively utilize the microphone from the connected peripheral, making it impossible to switch to the laptop's built-in microphone. For your reference, here are the specifications of my laptop and the Ubuntu version I am currently using: Laptop: Dell Vostro 3400 CPU: 11th Gen Intel i5-1135G7 GPU: Intel TigerLake-LP GT2 Iris Xe Memory: 2490MiB / 19720MiB Resolution: 1920x1080 OS: Ubuntu 22.04.3 LTS x86_64 Kernel: 6.5.0-14-generic DE: GNOME 42.9 Shell: bash 5.1.16 Sound Card: Card: HDA Intel PCH, Chip: Cirrus Logic CS8409/CS42L42 **UPDATE 12/02/2024 Noticed that every time my laptop fan starts spinning the crackling sound appears, after fan stops the crackling sound disappear. **UPDATE 19/03/2024 I did a software update to the linux kernel 6.5.0-26, now i get a dummy output in sound even if i restart the system many times, and if i use my Bluetooth headphone i can't use the mic, neither the mic of the laptop or of the headphone (there is no option is the settings to choose from) it's all blank.
