Hi Joseph -- I installed the linux-image and -extra debs, rebooted, chose 4.4.0-36 from the advanced menu, and things work as expected. Installation was fine as well.
Testing performed: * No frequency polling errors in kern.log (notice nothing since Sep 12 when I was running the ubuntu unpatched kernel, and it's now Sep 15): Sep 12 15:10:14 helo kernel: [ 50.823782] usb 2-1.2: 3:1: cannot get freq at ep 0x83 Sep 12 15:10:19 helo kernel: [ 55.827676] usb 2-1.2: 3:1: cannot get freq at ep 0x83 dpb@helo:~[0]$ date Thu Sep 15 16:57:29 MDT 2016 * Hangouts starts right up, no pausing upon launch * Sound can be selected in `pavucontrol`, no weird pauses or hangs * Sound file can be played from the command line fine, no pauses when starting.

These sample rate polls don't seem to keep happening. After waiting for maybe 30 seconds after sound is playing, future interactions will again trigger the pause. This 10 second pause can introduce other subtle problems. For instance, google hangouts will sometimes timeout waiting for the sound device to respond, and the browser tab will crash or not fully load as a result. The sound panel often also will not display the device in the list of choices, and you will have to close it out. Sometimes restart pulse audio to get it to recognize the headset again. == The solution == It is simple, add this USB ID to the sound/usb/quirks.c:snd_usb_get_sample_rate_quirk function. case USB_ID(0x1395, 0x740a): /* Sennheiser Officerunner */ version signature: Ubuntu 4.4.0-36.55-generic 4.4.16 # lsusb |grep Senn Bus 002 Device 004: ID 1395:740a Sennheiser Communications # zcat /var/log/kern.log.2.gz | grep 'cannot get' | tail -4 Sep 2 11:26:56 helo kernel: [908040.937098] usb 2-1.2: 2:1: cannot get freq at ep 0x4 Sep 2 11:27:01 helo kernel: [908045.941168] usb 2-1.2: 2:1: cannot get freq at ep 0x4 Sep 2 12:18:44 helo kernel: [911149.006318] usb 2-1.2: 3:1: cannot get freq at ep 0x83 Sep 2 12:18:49 helo kernel: [911154.010268] usb 2-1.2: 3:1: cannot get freq at ep 0x83 --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC3: dpb 12893 F.... pulseaudio /dev/snd/controlC2: dpb 12893 F.... pulseaudio /dev/snd/controlC1: dpb 12893 F.... pulseaudio /dev/snd/controlC0: dpb 12893 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=a9a39ff3-c97d-471e-a0b3-518b4db8685c InstallationDate: Installed on 2015-03-18 (544 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Alpha amd64 (20150306) MachineType: Hewlett-Packard HP Z620 Workstation NonfreeKernelModules: nvidia_uvm nvidia_modeset nvidia zfs zunicode zcommon znvpair zavl Package: linux (not installed) ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.4.0-36-generic.efi.signed root=/dev/mapper/vgroot-lvroot ro console=tty0 console=ttyS4,115200 nosplash nomdmonddf nomdmonisw ProcVersionSignature: Ubuntu 4.4.0-36.55-generic 4.4.16 RelatedPackageVersions: linux-restricted-modules-4.4.0-36-generic N/A linux-backports-modules-4.4.0-36-generic N/A linux-firmware 1.157.3 RfKill: 0: hci0: Bluetooth Soft blocked: no Hard blocked: no Tags: xenial Uname: Linux 4.4.0-36-generic x86_64 UpgradeStatus: Upgraded to xenial on 2016-02-16 (210 days ago) UserGroups: adm cdrom dip docker libvirtd lpadmin lxd plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 05/27/2015 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: J61 v03.88 dmi.board.asset.tag: 2UA41528ZC dmi.board.name: 158A dmi.board.vendor: Hewlett-Packard dmi.board.version: 0.00 dmi.chassis.asset.tag: 2UA41528ZC dmi.chassis.type: 6 dmi.chassis.vendor: Hewlett-Packard dmi.modalias: dmi:bvnHewlett-Packard:bvrJ61v03.88:bd05/27/2015:svnHewlett-Packard:pnHPZ620Workstation:pvr:rvnHewlett-Packard:rn158A:rvr0.00:cvnHewlett-Packard:ct6:cvr: dmi.product.name: HP Z620 Workstation dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1622763/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
