This problem has started to occur since the day I installed Ubuntu on my laptop. I installed first Ubuntu 18.04 LTS and this problem occurred. The problem is that whenever I turn my laptop on then sound turns on and off automatically during boot time and the time I use this laptop and while turning it off also. I have recently installed Ubuntu 20.04 LTS in this laptop in a bid to get my problem solved but it went in vain and the problem still exists. Please help me out as it really troubles me a lot. Please find a solution to this problem as soon as possible.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
