Public bug reported: Hello,
When in terminal, with my header on, if I press alternatively the "tab" key or the backspace key when there is no text, I get parasitic noise that come and go, in addition to the error sound. The parasitic noises are most often not loud, but they're here although they definitely shouldn't. Sometimes, it's quite loud too. The bug is not deterministic. Sometimes the tone is higher/lower. Sometimes it disappear on the first time I re-press one key among tab and suppress. Sometimes it requires more key pressing. I'm not sure whether the sound ends up by disapearing after a few retries, or if it just becomes too quiet for me to hear it. The bug doesn't occur when the sound is deactivated I feel like this has something to do with the error sound that is played when I delete and there is no character to delete It is not a big deal in itself. But maybe this very benign symptom hides a more serious issue idk. The sound comes out of my graphic card (nvidia gtx 980 ti) through a Samsung TV. I don't think the problem comes from either the graphic card or the TV, because it only happens in ubuntu, never in windows ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 5.8.0-50.56~20.04.1-generic 5.8.18 Uname: Linux 5.8.0-50-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27.16 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: guillaume 1669 F.... pulseaudio /dev/snd/pcmC1D0c: guillaume 1669 F...m pulseaudio /dev/snd/controlC2: guillaume 1669 F.... pulseaudio /dev/snd/controlC0: guillaume 1669 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Mon Apr 26 14:04:04 2021 InstallationDate: Installed on 2021-01-06 (110 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (20200731) PackageArchitecture: all ProcEnviron: PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=fr_FR.UTF-8 SHELL=/bin/bash SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:NVidia successful Symptom_Card: GM200 High Definition Audio - HDA NVidia Symptom_Jack: Digital Out, HDMI Symptom_PulsePlaybackTest: PulseAudio playback test successful Symptom_Type: None of the above Title: [hostname-M.2, Nvidia GPU 70 HDMI/DP, Digital Out, HDMI] Playback problem UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/17/2018 dmi.bios.release: 5.13 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: F23d dmi.board.asset.tag: Default string dmi.board.name: A320MA-M.2-CF dmi.board.vendor: Gigabyte Technology Co., Ltd. dmi.board.version: x.x dmi.chassis.asset.tag: Default string dmi.chassis.type: 3 dmi.chassis.vendor: Default string dmi.chassis.version: Default string dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrF23d:bd04/17/2018:br5.13:svnGigabyteTechnologyCo.,Ltd.:pnA320MA-M.2:pvrDefaultstring:rvnGigabyteTechnologyCo.,Ltd.:rnA320MA-M.2-CF:rvrx.x:cvnDefaultstring:ct3:cvrDefaultstring: dmi.product.family: Default string dmi.product.name: A320MA-M.2 dmi.product.sku: Default string dmi.product.version: Default string dmi.sys.vendor: Gigabyte Technology Co., Ltd. ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal third-party-packages -- 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/1926153 Title: [hostname-M.2, Nvidia GPU 70 HDMI/DP, Digital Out, HDMI] Playback problem in terminal Status in alsa-driver package in Ubuntu: New Bug description: Hello, When in terminal, with my header on, if I press alternatively the "tab" key or the backspace key when there is no text, I get parasitic noise that come and go, in addition to the error sound.
