[Kernel-packages] [Bug 1430696] Re: Bluetooth audio instability: Bluetooth: hci0 SCO packet for unknown connection handle
Same problem here on a DELL Latitude E7440 with Linux Mint 17.3 (based on Ubuntu 14.04 LTS) installed. When I use a Plantronics Voyager which connects directly to the notebook's internal bluetooth chip, I get these dmesg entries: $ dmesg | grep -i Bluetooth [3.994061] Bluetooth: Core ver 2.21 [3.994078] Bluetooth: HCI device and connection manager initialized [3.994082] Bluetooth: HCI socket layer initialized [3.994085] Bluetooth: L2CAP socket layer initialized [3.994095] Bluetooth: SCO socket layer initialized [4.014377] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [4.014381] Bluetooth: BNEP filters: protocol multicast [4.014384] Bluetooth: BNEP socket layer initialized [4.017044] Bluetooth: RFCOMM TTY layer initialized [4.017049] Bluetooth: RFCOMM socket layer initialized [4.017054] Bluetooth: RFCOMM ver 1.11 [4.119489] Bluetooth: hci0: read Intel version: 370710018002030d37 [4.119491] Bluetooth: hci0: Intel device is already patched. patch num: 37 [ 32.154782] Bluetooth: hci0 SCO packet for unknown connection handle 0 [ 32.164817] Bluetooth: hci0 SCO packet for unknown connection handle 0 [ 32.164821] Bluetooth: hci0 SCO packet for unknown connection handle 0 [ 572.934811] Bluetooth: hci0 SCO packet for unknown connection handle 0 [ 572.934815] Bluetooth: hci0 SCO packet for unknown connection handle 0 [ 572.934817] Bluetooth: hci0 SCO packet for unknown connection handle 0 [ 641.073418] Bluetooth: hci0 SCO packet for unknown connection handle 0 [ 646.105832] Bluetooth: hci0 SCO packet for unknown connection handle 257 [ 646.105837] Bluetooth: hci0 SCO packet for unknown connection handle 257 [ 646.105839] Bluetooth: hci0 SCO packet for unknown connection handle 257 The headset is not correctly recognized. Sometimes works, sometimes doesn't (sound output works better than input, microphone seems not available). In VMware Player, the headset is not recognized to add as a removable device into the VM. However if I use an almost identical headset, also a Plantronics Voyager but with a bluetooth usb dongle, I get no problems at all and I am able to add it as a removable device into the VM. So same OS, same hardware but different handling of internal bluetooth vs. bluetooth dongle. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1430696 Title: Bluetooth audio instability: Bluetooth: hci0 SCO packet for unknown connection handle Status in linux package in Ubuntu: Confirmed Bug description: (I'm creating a new bug as instructed at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/898347/comments/29) I havea Nokia BH-216 bluetooth headset.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.0 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[Kernel-packages] [Bug 1430696] Re: Bluetooth audio instability: Bluetooth: hci0 SCO packet for unknown connection handle
I'd like to add that i have now a different laptop (Lenovo E540) than previously, so the bug most probably isn't in the general bluetooth hardware drivers. Other people suffer from the bug with a large variety of hardware. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1430696 Title: Bluetooth audio instability: Bluetooth: hci0 SCO packet for unknown connection handle Status in linux package in Ubuntu: New Bug description: (I'm creating a new bug as instructed at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/898347/comments/29) I havea Nokia BH-216 bluetooth headset.
