@Hui Wang My problem is different from the comment you provided, LOL. 1. I'm using Kubuntu. Kubuntu DOESN'T HAVE the POPUP-DIALOG because KDE environment uses PulseAudio to manage audio system. When a user plug in a headset there are no options to choose from, the program sets it automatically. It's the same problem in Xfce4 of Xubuntu. 2. Before I plug in, the capture is the internal one. But when I do, the settings automatically changes to 'Microphone' or 'Headset Microphone', in both situation my headset is unable to work.(KDE envionment, all these settings are accessible in PulseAudio) Only after I've change the setting to 'Internal Microphone' manually could I hear the voice. 3. I installed Ubuntu Desktop and tested the problem in the environment. The POPUP-DIALOG shows with the 3 options when I plug in headset. 'Microphone' option can make my headset work. 'Headset' option makes the same problem as KDE&Xfce4 one. 4. Does the Dell laptop you got have the 2 x 3.5mm Headset Jack or the 1 x 3.5mm Headset Jack which is same as my laptop? Or there is something different in the circuit design or audio device firmware settings that makes the differences appear.
Anyway, thank you for your help. Without it I can't dig in the problem and find something. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1873384 Title: [Dell Inspiron 5577] Headphone has no sound out Status in linux package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Computer: Dell inspiron 15 5577 Gaming intel i5 7300HQ version System: Kubuntu 20.04 Bug: Plug-in headphone has no sound out, meanwhile computer's speaker is okay when unplugged the headphone.
