Checking a bit more, I've realized the following: - After a reboot, the microphone is not detected and nothing is proposed in pavucontrol
- If I plug any headphone (3-pins without mic) then the "Internal microphone" device appears. Which doesn't also don't work (neither output nor input). After unplugging the headphone, sometimes the mic starts working despite manually selecting it. I cannot find the combination to make the mic work all the time. - If I plug a headset with (4-pins including mic) when the Input device is changed to Port: Headset Microphone (plugged in) in pavucontrol, and I get sound on the headphones only on the left channel. Strangely enough if I change the microphone setting I lose the sound again, why the input should affect the output. - USB headset with microphone works both ok. -- 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/1877580 Title: [Latitude 7490, Realtek ALC3246, Black Headphone Out, Front] No sound at all Status in alsa-driver package in Ubuntu: New Bug description: After upgrade from 19.10 to 20.04 (xubuntu) I've lost the sound on the headphones. The internal loud speakers works ok when the headphones are not plugged in. More specifically: If I open the pavucontrol without the headphones plugged in I see that is correctly mentioning the output as Port: "Speakers (plugged-in)" and everything works ok, I have sound from the speakers. The moment I plug in the headphones, for a fraction of a second I can hear sound on the headphones, and then the output port switches to "headphones" which is the moment I lose the sound. The fraction that I hear the sound is when the jack is half-inserted and I get the sound on one channel only. When is fully inserted, the computer detects it and makes the switch. I've tried also in alsamixer all possibilities I could imagine, playing with mute/unmute and gain of each channel, with no success ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 5.4.0-29.33-generic 5.4.30 Uname: Linux 5.4.0-29-generic x86_64 ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: bnv 1312 F.... pulseaudio bnv 21367 F.... alsamixer /dev/snd/pcmC0D0c: bnv 1312 F...m pulseaudio /dev/snd/pcmC0D0p: bnv 1312 F...m pulseaudio CasperMD5CheckResult: skip CurrentDesktop: XFCE Date: Fri May 8 15:41:08 2020 InstallationDate: Installed on 2019-08-08 (274 days ago) InstallationMedia: Xubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:PCH failed Symptom_Card: Built-in Audio - HDA Intel PCH Symptom_DevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: bnv 1312 F.... pulseaudio bnv 21367 F.... alsamixer /dev/snd/pcmC0D0c: bnv 1312 F...m pulseaudio /dev/snd/pcmC0D0p: bnv 1312 F...m pulseaudio Symptom_Jack: Black Headphone Out, Front Symptom_Type: No sound at all Title: [Latitude 7490, Realtek ALC3246, Black Headphone Out, Front] No sound at all UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 11/08/2019 dmi.bios.vendor: Dell Inc. dmi.bios.version: 1.13.1 dmi.board.name: 0KP0FT dmi.board.vendor: Dell Inc. dmi.board.version: A00 dmi.chassis.type: 10 dmi.chassis.vendor: Dell Inc. dmi.modalias: dmi:bvnDellInc.:bvr1.13.1:bd11/08/2019:svnDellInc.:pnLatitude7490:pvr:rvnDellInc.:rn0KP0FT:rvrA00:cvnDellInc.:ct10:cvr: dmi.product.family: Latitude dmi.product.name: Latitude 7490 dmi.product.sku: 081C dmi.sys.vendor: Dell Inc.
