Buzzing sound after 1.5 to 3 minutes playing audio or video

es flag

I have Ubuntu 21.10 installed on ACER Aspire switch 10 laptop/tablet. When I play audio or video using internal speakers for sound output, after 1.5-3 minutes I get buzzing sound from the speakers instead of played audio. Then I restart the application and it helps. This occurs for any application playing audio (vlc, mpv, firefox). But when I use Bluetooth audio as output everything works perfect. What should I check and where to look?

UPD:

I tested the internal speakers with installer USB in 'Try Ubuntu' mode.

Ubuntu 21.10 installer USB (try mode) - starts buzzing

Ubuntu 20.04 installer USB (try mode) - NO buzzing (i.e. works fine)

So I think this is clearly a software issue.

Also I tested external HDMI audio (TV) as output - NO buzzing (i.e. works fine)

So how do I find and check the sound settings ?

This might be a hardware issue. Can you see if the problem occurs when using a live CD?

Live CD: with 21.10 it starts buzzing, with 20.04 it works perfectly (i.e. NO buzzing). Now it is clear that this is software issue. Thank you. Now the question is - is it wrong settings or bug in code. So how do I find and check the sound settings ?

it looks like you have these issues vanished using external ac/dc plugged devices or own power source, have you tried some static extraction? (did u dissamblee your device previously?)

The problem (buzzing) with internal speakers in 21.10 did NOT vanish. All the described tests I did with AC adapter plugged in. What do you mean by 'static extraction'? I do not remember right now if I ever disassembled the device... Maybe I replaced a battery some time ago, but not sure. But how is it connected to the buzzing problem?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
