When my laptop is docked, I expect the internal speakers to cease functioning to let the monitor speakers take over. Instead, both the laptop and monitor speakers play audio at the same time.
Laptop is a Dell Latitude E6420 and the docking station is a Dell PR03X. Monitor speakers are connected to the 3.5mm jack on the dock.
In MATE's Sound Preferences: The hardware tab lists "Built-in Audio; 1 Output/2 Inputs" and "Webcam C270; 1 Input". For profiles I have Analog Stereo Duplex, Output, Input, and Pro Audio; none of which only outputs to the monitor speakers. | The Output tab lists one device "Built-in Audio Analog Stereo". I have 3 options in the "Connector" drop down menu; Line Out, Headphones, and Speakers. "Headphones" produces no audio at all, "Line Out" and "Speakers" produces audio from both internal and monitor speakers.
I've installed pipewire; partially as a troubleshooting step(which seemed to change nothing of the issue), and partially because I'm ornery about audio clarity from software. I plan on keeping pipewire.
There is no change in # dmesg when plugging or unplugging the 3.5mm jack from the dock. There is only one analog audio device listed in aplay -l; all others are HDMI which there are no HDMI devices in this setup.
Code:
~$ aplay -l
