I recently bought the Dell MH3021P speakerphone. I want to use it for hybrid meetings and for recording audio during lectures. Dell doesn’t say the device supports Linux, so I was curious to see how much of the device works. Google didn’t have an answer so I bought the device to test it for myself.
Thankfully I can say all the important parts work very well out of the box on Ubuntu 22.04!
What works on Linux
- Using the speaker and microphone from the device for calls. The audio is very clear and picks up everyone’s voice when it’s sitting in the middle of the table.
- Using the internal USB-C docking station. HDMI output, regular USB ports and USB-c ports all work as expected!
- Charging your laptop from the speakerphone. Connect your charger to the speakerphone, connect the speakerphone to your laptop and your laptop starts charging!
- The volume buttons on the speakerphone change the volume of my Ubuntu laptop (with GNOME).
What does not work on Linux
- The mute button does nothing. I tried it with both Zoom and Microsoft Teams, and it doesn’t seem to work. Moreover, it doesn’t even mute its own microphone.
- The “accept call” and “hangup” button don’t do anything either. I also tested this with Zoom and Microsoft Teams.
If you are interested in figuring out why these things don’t work and how to get them to work, let me know in the comments or send me an email!
Appendix: device logs and info
In case this is of interest or useful to anyone, these are some logs that give a bit more information about the internals of the device.
