1, it's a known issue with some old version firmware(ref: http://www.spinics.net/lists/linux-bluetooth/msg39377.html), please upgrade to this one: https://git.kernel.org/cgit/linux/kernel/git/firmware/linux- firmware.git/tree/intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq
2, it's not possible to fix this on lts-quantal, lts-raring and lts- saucy, they are all EOL or missed the last day for kernel commits for last cycle. So, I will close linux-lts-saucy branch as Won't fix. Feel free to reopen it on Trusty or further version if your testing result is negative. ** Changed in: linux-lts-saucy (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310558 Title: Intel [8087:07dc] Bluetooth headset only works in A2DP mode on Dell Latitude E5440 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-saucy/+bug/1310558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
