** Description changed: After first install of Ubuntu 14.04.2 LTS on brand-new HP Zbook 15 G2 I wanted to listen to music. Sound works. However, there is a constant, quite strong very annoying noise. This noise appears only when I use headphones. And the volume of this noise seems to be independent of the volume I chooses on the system. It is there permanently. (it's really annoying, making this perfect machine unusable in this regard) I am using the normal analog 3.5mm headset port on the right hand side. I can confirm, that it is not a problem of the headphones, I tested it with 3 different ones. Same result. Annoying noise. It seems to be a mix of white noise and some other varying frequencies. Also, if I run the volume all the way down to mute, the noise stops. (which seems to confirm a software/driver problem right?) HP claims to support Ubuntu 14.04 on this brand-new workstation ! - More info here : http://askubuntu.com/questions/599539/noise-on- - headphones-on-hp-zbook-15-g2-with-ubuntu-14-04-2-or-14-10 + More info here : http://askubuntu.com/questions/599539/noise-on-headphones-on-hp-zbook-15-g2-with-ubuntu-14-04-2-or-14-10 + --- + ApportVersion: 2.14.1-0ubuntu3.7 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: eric 1560 F.... pulseaudio + /dev/snd/controlC1: eric 1560 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=5565fff9-d47c-465c-9ef6-7bb37610caca + InstallationDate: Installed on 2015-03-21 (0 days ago) + InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) + MachineType: Hewlett-Packard HP ZBook 15 G2 + Package: linux (not installed) + ProcFB: 0 radeondrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-31-generic root=UUID=81792a20-09a6-47d9-be7f-0a6de44a41dd ro quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 3.16.0-31.43~14.04.1-generic 3.16.7-ckt5 + RelatedPackageVersions: + linux-restricted-modules-3.16.0-31-generic N/A + linux-backports-modules-3.16.0-31-generic N/A + linux-firmware 1.127.11 + RfKill: + 0: phy0: Wireless LAN + Soft blocked: yes + Hard blocked: no + Tags: trusty + Uname: Linux 3.16.0-31-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 02/26/2015 + dmi.bios.vendor: Hewlett-Packard + dmi.bios.version: M70 Ver. 01.07 + dmi.board.name: 2253 + dmi.board.vendor: Hewlett-Packard + dmi.board.version: KBC Version 03.10 + dmi.chassis.type: 10 + dmi.chassis.vendor: Hewlett-Packard + dmi.modalias: dmi:bvnHewlett-Packard:bvrM70Ver.01.07:bd02/26/2015:svnHewlett-Packard:pnHPZBook15G2:pvrA3008CD10003:rvnHewlett-Packard:rn2253:rvrKBCVersion03.10:cvnHewlett-Packard:ct10:cvr: + dmi.product.name: HP ZBook 15 G2 + dmi.product.version: A3008CD10003 + dmi.sys.vendor: Hewlett-Packard ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1434963/+attachment/4352024/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434963 Title: Noise on headphones with 14.04.2 on HP Zbook 15 G2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1434963/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
