[Bug 1896782] Re: Sound card stops working suddenly

[Surya Kiran]

What I found was every now and then the audio device profile is getting
turned off, which is resulting in no audio.

Title:
  Sound card stops working suddenly

Status in ubiquity package in Ubuntu:
  New

Bug description:
  Ubuntu 20.04 latest update. 
  With the latest update the sound goes off all of a sudden. Rebooting helps, but only for an hour or so. I tried re-installing alsa-base et al. No luck. PulseAudio Volume Control is not listing my soundcard at all.

  I'm using NVIDIA GEForce GTX 1660Ti with NVIDIA 450.57 driver.
