@Iain, For focal, after we merge this SRU: https://bugs.launchpad.net/ubuntu/+source/alsa-utils/+bug/1899745, we will have this bug too. But for focal, the #1899745 will not be in the iso, so users will not notice this problem. If we merge #1899745 to 20.04.2 iso, users will meet this bug.
So for focal, this fix is not very urgent, even we merge the #1899745, it will not introduce this issue immediately. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-lib in Ubuntu. https://bugs.launchpad.net/bugs/1897934 Title: [SRU][Intel HDA] The initial sound level is set to zero (muted) Status in Release Notes for Ubuntu: New Status in alsa-lib package in Ubuntu: Fix Committed Status in alsa-lib source package in Focal: Incomplete Status in alsa-lib source package in Groovy: Fix Committed Bug description: [Impact] Fail to run '/usr/sbin/alsactl restore' on the HDA-Intel machines, this results in the failure on setting the init mixer values for HDA sound card, and users experience the mute of audio after installing the 20.10. [Fix] Backport a patch from the latest alsa-lib (v1.2.3+) [Test] Without the patched alsa-lib, rm ~/.config/pulse/*;sudo rm /var/lib/alsa/*; sudo sh -c "echo b > /proc/sysrq-trigger", after booting up, the audio is muted. Install the patched alsa-lib, rm ~/.config/pulse/*;sudo rm /var/lib/alsa/*; sudo sh -c "echo b > /proc/sysrq-trigger", after booting up, the audio is not muted. [Regression Potential] This could make the ucm audio fail to initialize, but this possibility is very low, since this patch is from upstream, and I tested on a ucm based machine, the audio is good. On boot into the live session - or on first install the sound level is muted. I have to use GNOME Control Center - Sounds to change to an appropriate level. Once changed the level chosen is correctly retained between reboots. This appears to be a regression from 20.04 where the sound level was set to - I guess - 80% on the live-session/first install ProblemType: BugDistroRelease: Ubuntu 20.10 Package: pulseaudio 1:13.99.1-1ubuntu11 ProcVersionSignature: Ubuntu 5.8.0-20.21-generic 5.8.10 Uname: Linux 5.8.0-20-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu48 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu-budgie 5041 F.... pulseaudio CasperMD5CheckResult: pass CasperVersion: 1.452 CurrentDesktop: Budgie:GNOME Date: Wed Sep 30 16:03:08 2020 LiveMediaBuild: Ubuntu-Budgie 20.10 "Groovy Gorilla" - Beta amd64 (20200930) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bashSourcePackage: pulseaudio UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 02/15/2016 dmi.bios.release: 15.31 dmi.bios.vendor: Insyde dmi.bios.version: F.1F dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: 80BF dmi.board.vendor: HP dmi.board.version: 95.16 dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.chassis.version: Chassis Version dmi.ec.firmware.release: 95.22 dmi.modalias: dmi:bvnInsyde:bvrF.1F:bd02/15/2016:br15.31:efr95.22:svnHP:pnHPNotebook:pvr:rvnHP:rn80BF:rvr95.16:cvnHP:ct10:cvrChassisVersion: dmi.product.family: 103C_5335KV G=N L=CON B=HP dmi.product.name: HP Notebook dmi.product.sku: N9S73EA#ABU dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1897934/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
