Identical symptoms, package version, distro version, also ALC298, also tried windows, only difference is computer model (Lenovo T570). Confirmed on two identical computers with identical setups. Sorry, don't know how to generate a new report or add debug info.

No option to go above 100% in volume settings. Download pulse audio volume control to raise application and output volume to 153%, which helps to some extent, but then leads to distortion. Was running windows 10 on same system and audio was loud enough! Also after this morning s update, the volume keys no longer work, even after re-mapping them in shortcuts.3 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 4.15.0-13.14-generic 4.15.10 Uname: Linux 4.15.0-13-generic x86_64 ApportVersion: 2.20.9-0ubuntu4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jatin 2098 F.... pulseaudio CurrentDesktop: Budgie:GNOME Date: Sun Apr 8 22:50:04 2018 InstallationDate: Installed on 2018-03-23 (17 days ago) InstallationMedia: Ubuntu-Budgie 18.04 LTS "Bionic Beaver" - Alpha amd64 (20180307.1) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:PCH successful Symptom_Card: Built-in Audio - HDA Intel PCH Symptom_Jack: Speaker, Internal Symptom_PulsePlaybackTest: PulseAudio playback test successful Symptom_Type: High background noise, or volume is too low Title: [20HCS06601, Realtek ALC298, Speaker, Internal] Background noise or low volume UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/03/2017 dmi.bios.vendor: LENOVO dmi.bios.version: N1VET36W (1.26 ) dmi.board.asset.tag: Not Available dmi.board.name: 20HCS06601 dmi.board.vendor: LENOVO dmi.board.version: SDK0J40697 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN1VET36W(1.26):bd10/03/2017:svnLENOVO:pn20HCS06601:pvrThinkPadP51s:rvnLENOVO:rn20HCS06601:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad P51s dmi.product.name: 20HCS06601 dmi.product.version: ThinkPad P51s dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1762314/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
