Public bug reported:
The sound just is extremely distorted after update to 18.04. Like an old
radio that's not picking up the station right. I saw a webpage about the
same device I am using and tried their solution. That didn't help at
all. Hope I didn't make things worse.
I saw a page that mentioned the lspci command. Based on that, I guess I
am using an Intel 82801 JD/DO audio card. One site said that requires an
snd_hda_intel driver, but all I could find in Synaptic Package Manager
was that an alsa driver and pulse audio were installed. Could the
correct driver have been removed with the new installation?
This computer has been kind of buggy as of late, but the audio had been
working. I had problems installing this OS. Mostly it seems to be
working otherwise though.
1) Description: Ubuntu 18.04.1 LTS
Release: 18.04
2) N: Unable to locate package pkgname
3) What you expected to happen: sound to work properly
4) What happened instead: sound distorted
Hope my attempt to fix it doesn't screw up the bug report.
