But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed. ** Changed in: alsa-driver (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1838071 Title: Recording sound is impossible on Dell Latitude 7350 [broadwell-rt286] Status in alsa-driver package in Ubuntu: Won't Fix Bug description: Since Ubuntu 16.04, it is impossible to use the microphone of headsets (those which come with 4 ring jack connector). The main microphone is sometimes usable (I think it's okay with Ubuntu 18.04). With Ubuntu 19.04, neither the embedded (main) microphone nor those on headsets are functional, I thus cannot record any sound. I've read many things, tried many modifications of /etc/modprobe.d /alsa-base.conf in order to let the Internal Broadwell audio card be seen before HDMI audio, for example. Here is the Alsa diagnostic I ran : http://alsa- project.org/db/?f=06e98f49dcfaf88991b4a992e66409b71976f038 I also verified everything was fine with alsamixer -c1 (broadwaell- rt286 is second by default). I also tried to use pavucontral, as under Ubuntu 18.04 it helped me to "start" the embedded microphone. With this tool, under Ubuntu 19.04, I see strange settings : there is an "internal audio main microphone + handset microphone" entry, there once were 2 entries. And the handset microphone is always "plugged in" and the "main microphone" is always unplugged.
