Ubuntu distorts sounds at higher volume

cn flag

I recently (~2 weeks) switched to Ubuntu and the sound is crazy distorted at volumes higher than 50%. At 50%, the speaker volume is not high enough for regular usage. I've so far tried tweaking around with AlsaMixer and replacing PulseAudio with Pipewire and neither solved my problem.

How do i fix this?

To see a sample of the distortion, here's a 45 second video. You can skip ahead to 35 (-10) seconds / 15 (-30) seconds to hear the distortion.

Note - this isn't an issue with the speakers/hardware as they worked perfectly fine when I used Windows.

I own an Acer Swift 3 (2018 version) - SF314-52. Terminal Output of sudo lspci -v:

Updating: adding output of aplay -l:

Unfortunately there is not a great deal of actionable information here. Audio clarity is incredibly subjective, as a lot of people seem to think that listening to music from the speaker on their phone is “perfectly fine”. Based on your question, I’m going to assume that you know the difference between `.flac` and `.mp3`. With this in mind, could you [edit] your question to include the brand and model of your computer (or motherboard if it’s a custom-build), and the Terminal output of `sudo lspci -v` for the audio device? With this, a solution or more specific questions may be presented

Thanks, I've added device information and terminal output.

Hmm ... it may be necessary to explicitly name the driver to use in your `alsa-base.conf` file. Could you [edit] your question (again) to include the output of `aplay -l`? This will show which specific drivers are currently assigned.

I've added this information too. Is HDA Intel PCH the driver?

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.
