Bug Description

[SRU Justification]

When using a bluetooth headset the ad2p profile is supported but the
hsp/hfp profile doesn't work.

Using the latest firmware with patch version 42 solves from commit
629a5e089e30 ("linux-firmware: Update firmware patch for Intel
Bluetooth 7260 (B5/B6)").

[Test Case]
Pair with headset/mobile phone with HSP/HFP support and try A/V

[Regression Potential]
Low. This upgrades only the firmware blob used by affected hardware,
and the proposed blob is also used by later releases.

========== original bug description ==========

--ubuntu release :
lsb_release -d
Description: Ubuntu 18.04.3 LTS

-- package :
apt show linux-firmware 2>&1 | grep -i "version:\|package:"
Package: linux-firmware
Version: 1.173.12

--hardware :
lspci -vnn | grep irel
03:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev bb)
 Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:4070]
lsusb -d 8087:07dc
Bus 001 Device 003: ID 8087:07dc Intel Corp.

--problem :
The bluetooth part of the intel 7260 wifi/bluetooth card needs a firmware file to operate.
The version of my card is reported in dmesg as :

Bluetooth: hci0: read Intel version: 3707100180012d0d00

this will load firmware file

Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.7.10-fw-

When using a bluetooth headset the ad2p profile is supported but the hsp/hfp profile doesn't work, I believe the version in the current linux-firmawre package is patch version 39.

--solution :
Using the latest firmware with patch version 42 solves the problem :


With this firmware the hsp/hfp profile is working, this means the microphone and the sound of the bluetooth headset are working correctly.

Yes, the latest revision of that blob in bionic branch has patch version 39: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux-firmware/commit/intel/ibt-hw-37.7.10-fw- . This should only affect Bionic because Cosmic and later releases have already patch version 42.

Hello <email address hidden>, or anyone else affected,

Accepted linux-firmware into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/1.173.13 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I confirm that the package fix the bug.

I downloaded it from :

I believe it may be necessary to halt, wait some seconds then start the computer after install (and not just restart the computer) as the firmware is loaded directly in the bluetooth adapter.
