All sliders are up in alsamixer, sound is around half-volume compared to the Windows install. ALSA Driver Version: k4.14.67-1-MANJARO. these did not help: https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture/Troubleshooting#Volume_is_too_low

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
