Sound Output Coming From Headphones and Internal Speakers

[kisun]

Instead that is a driver problem have you take a look if “Auto Mute” is enabled in Alsamixer?

You can start ‘alsamixer’ from terminal, choose the right soundcard with ‘F6’ and navigate to the right to the “Auto Mute”-option.

Headphones, Speaker playing simultaneously

Hi, I am new to linux, The speakers on my PC work fine, but when I plug in headphones (which also work fine) I expect the computer speakers to mute. They don’t. How can I get my speakers to mute automatically when I plug my headphones into the jack?

or this:

Sound playing from headphones and speakers

The sound is playing from my speakers and headphones, In Linux Mint I used HDAjackretask to fix this issue but it doesn’t appear to be available for Arch.

Perhaps it helps.
