Comment 0 for bug 2049628

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:
