apport information ** Tags added: apport-collected package-from-proposed running-unity third-party-packages
** Description changed: 1) The release of Ubuntu using Ubuntu 12.10 64-bit. 2) The version of the package used linux-image-3.5.0-26-generic 3) What you expected to happen Audio being played smoothly without breaks and cracking sound. 4) What happened instead After upgrading to Linux kernel 3.5.0-26-generic, one of my USB DAC (Digital Audio Codec) suddenly started to produce constently discontinous sound. Whenever there is audio being played by the system, the outcome would be always accompany with regular, stable, 5 to 6 times per second breaks. Both the system sound and songs from media player failed. One of my USB DAC works under Asynchronous Mode (USB device host clock), the other one works under Synchronous Mode (Motherboard host clock). The Synchronous one worked as usual after the updrade, while the Asynchronous one did not. - I downgraded the package to the previous 3.5.0-26-generic, then - everything went back to normal. + I downgraded the package to the previous 3.5.0-26-generic, then everything went back to normal. + --- + ApportVersion: 2.6.1-0ubuntu10 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: tysontan 2117 F.... pulseaudio + /dev/snd/controlC1: tysontan 2117 F.... pulseaudio + /dev/snd/pcmC1D0p: tysontan 2117 F...m pulseaudio + CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found. + DistroRelease: Ubuntu 12.10 + HibernationDevice: RESUME=UUID=8545c3e2-caba-4eaa-8fa4-2fbebcc2d9bb + InstallationDate: Installed on 2013-02-15 (14 days ago) + InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) + IwConfig: + eth0 no wireless extensions. + + lo no wireless extensions. + MachineType: LENOVO 0053A11 + MarkForUpload: True + Package: linux 3.5.0.26.32 + PackageArchitecture: amd64 + ProcEnviron: + TERM=xterm + PATH=(custom, no user) + XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.5.0-26-generic root=UUID=8c60a142-505f-4d74-afa0-37686558e86e ro quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 3.5.0-26.40-generic 3.5.7.6 + RelatedPackageVersions: + linux-restricted-modules-3.5.0-26-generic N/A + linux-backports-modules-3.5.0-26-generic N/A + linux-firmware 1.95 + RfKill: + + Tags: quantal package-from-proposed running-unity third-party-packages + Uname: Linux 3.5.0-26-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + dmi.bios.date: 10/11/2012 + dmi.bios.vendor: LENOVO + dmi.bios.version: 6QET70WW (1.40 ) + dmi.board.name: 0053A11 + dmi.board.vendor: LENOVO + dmi.board.version: Not Available + dmi.chassis.asset.tag: No Asset Information + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: Not Available + dmi.modalias: dmi:bvnLENOVO:bvr6QET70WW(1.40):bd10/11/2012:svnLENOVO:pn0053A11:pvrThinkPadX201Tablet:rvnLENOVO:rn0053A11:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: + dmi.product.name: 0053A11 + dmi.product.version: ThinkPad X201 Tablet + dmi.sys.vendor: LENOVO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1136110/+attachment/3553684/+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/1136110 Title: Asynchronous USB DAC cracking sound in Linux kernel 3.5.0.26 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
