Title:
[Latitude 7440, Realtek ALC289, top speakers and headphones play at
same time
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
The laptop has 2 speakers on the bottom and 2 speakers on the top.
When plugging headphones into the 3.5mm jack, the bottom speakers are
auto-muted as they are supposed to be (confirmed this in alsamixer);
the top speakers however continue to output sound- the headphones work
fine, but the top speakers play at the same time.
If you go into alsamixer to play with levels, you will note that
changing "headphones" volume also changes the volume of the speakers
on the top. In fact, even with the headphones unplugged, alsamixer
shows a "headphones" section (which will control top speaker volume).
The bottom speakers which are muted properly are called "Speakers" in
alsamixer. It seems this is a pin issue- it seems that the headphones
and the top speakers are linked in some way.
The headphone plug action properly mutes all speakers on Windows 11,
so this seems to be a software issue.
In case it helps: I have reproduced this behavior on Ubuntu 23.10's
live installer, and also on Fedora 39 Workstation's live installer. My
Ubuntu 22.04 install is completely up-to-date.
