When the jack is inserted the internal speakers stop making sound and the only analog out is the jack, as it’s common on laptops. But I want to address the two analog output individually so that I can:

• Still select the speakers when headphones are plugged
• Have different sounds come from headphones and speaker
• Mix them with carla or other audio software

My alsa/pipewire settings are all default, I’m on a thinkpad t480s with fedora 38. My sound card is an intel hd audio card, with a realtek ALC257 analog chip.

I tried disabling auto_mute and rising the volume from alsamixer but nothing happens. Then I switching pipewire to “pro audio” but it doesn’t separate the analog outputs. I also tried setting the indep_hp hint from hdarackretask but it doesn’t change anything.

The hint enables a new “independent hp” option in alsamixer, but it can only be enabled by the cli and it doesn’t work either.

I can provide configuration files or other info if needed but since they are all pretty long I didn’t include them in the post. Also because I didn’t edit them so they are just fedora’s default.

Thanks
