Intel [8087:07dc] Bluetooth headset only works in A2DP mode on Dell Latitude E5440

[Po-Hsu Lin]

CID: 201307-13941 Dell Latitude E5440

The Bluetooth HSP/HFP mode does not work on this system,
however, this chipset, 8087:07dc, works fine on 201307-14037 with the same kernel.
lsusb -v output for this device slightly different on these two system
(difference in the bus number and device number)

Steps:
1. Install 12.04.4 + update (3.11.0-19), boot to desktop
2. Pair with a Bluetooth headset
3. Set this Bluetooth headset as Input / Output source in "Sound Settings"
4. Speak into your headset, use "Sound recorder" to record with HSP/HFP mode
5. Test playback functionality in HSP/HFP mode
6. Switch to A2DP mode, play sound to test it.

Expected results:
* Bluetooth headset works fine in HSP/HFP and A2DP mode

Actual results:
* It only works in A2DP mode, unable to record and play a sound in HSP/HFP mode.

The difference between these two system could be found in lsusb -t result, for this one, it's on level 3, with a hub driven by ehci-pci driver.

[Adam Lee (adam8157)]

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.

[Adam Lee (adam8157)]

#3 was a mistake. Sorry.

Last SRU cycle including lts backports starts the 24th of July, so we still have plenty of time.

[Adam Lee (adam8157)]

@Po-Hsu, could you please test the new firmware in #3(same name but different binary)? thanks.

[Po-Hsu Lin (cypressyew)]

Hello Adam,
after replacing the ibt-hw-37.7.10-fw-1.80.2.3.d.bseq in /lib/firmware/intel
this issue still exist

Steps:
1. Install 12.04.4 + update (3.11.0-20), reboot
2. Pair with a Bluetooth headset, make sure this issue still exist.
3. Stop Bluetooth by using the hardware switch
4. Replace the ibt-hw-37.7.10-fw-1.80.2.3.d.bseq
5. Re-activate the Bluetooth, test the headset again.
6. Reboot, test the headset again.

Expected result:
* Headset in HSP/HFP mode should be not working properly before step 4 or 6
* Headset in HSP/HFP mode should work on step 6

Actual result:
* Headset in HSP/HFP mode didn't work properly at all.

[Adam Lee (adam8157)]

@Po-Hsu, how about the cold boot? I also have another question, why the usb hub routing config is different between two OS version? Could you please reset BIOS to default and cold boot to test? Thanks.

[Po-Hsu Lin (cypressyew)]

Hello Adam,
You mean the config is different between 201307-13941 and 201307-14037?

After BIOS reset and cold boot, this issue still exist
(after replacing ibt-hw-37.7.10-fw-1.80.2.3.d.bseq)

[Adam Lee (adam8157)]

@Po-Hsu, can this system's BIOS route all usb ports to usb3.0? like a option "USB3 Mode", if it exists, please try to set it to Enable and test

[Adam Lee (adam8157)]

@Po-Hsu, could you please test this one?

[Po-Hsu Lin (cypressyew)]

Hello Adam,
there is only an option called "Enable USB3.0 Controller", and it is enabled by default.

And...
this firmware works!

Steps (3.11.0-20 on 201307-13941):
1. Disable the Bluetooth, replace the /lib/firmware/intel directory
2. Reboot, enable the Bluetooth and test the headset

Expected result:
* Headset works in both HSP/HFP and A2DP mode

Actual result:
* Bluetooth headset works as expected.

Thanks!

[Adam Lee (adam8157)]

@Po-Hsu, great, but that firmware is not in upstream yet... will push the maintainer

[Adam Lee (adam8157)]

linux-firmware upstream has not seen any new development activity for two months, I'm still pushing.

[Adam Lee (adam8157)]

new firmware shows up in upstream, patch is sent to kernel-team@

[Brad Figg (brad-figg)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-saucy' to 'verification-done-saucy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Adam Lee (adam8157)]

Could anyone open the Trusty branch? Certification team wants that.

[Adam Lee (adam8157)]

The fix(new firmware) is already in Trusty and Utopic.

[Po-Hsu Lin (cypressyew)]

Hello Adam,
Could you tell me which version of the firmware is?

Verified on 201307-13941 with 14.04 + update(3.13.0-29), with firmware version (1.127.2)
But it's still not working (HSP/HFP)

Also, firmware in #10 somehow does not work with 12.04.4 stock image on 201307-13941 as well.

[Adam Lee (adam8157)]

Trusty 1.127.3, Utopic 1.131, seems the status of trusty should be "fix committed", sorry.

[Tim Gardner (timg-tpi)]

Saucy is going EOL soon. Only critical CVEs until then.

Series nominated for Precise.
Bluetooth HID devices are not stable on 201303-13111 as well, the Bluetooth mouse / keyboard works for the first time, but they're not working now.

@Adam, could we backport this fix to Precise?
To see if it can fix the BT HID devices issue.

[Adam Lee (adam8157)]

@Po-Hsu, you could install linux-firmware from trusty directly to test.

[Adam Lee (adam8157)]

@Po-Hsu, 12.04 or 12.04.5? I don't see a chance that kernel-team will accept a new driver feature(intel patchram) into 12.04.

[Po-Hsu Lin (cypressyew)]

Hello Adam,
I installed the .deb file from https://launchpad.net/ubuntu/+source/linux-firmware/1.127.4/+build/6132013

After cold boot, this issue does not exist anymore.

We would like to have it fixed in 12.04.5
(I think Precise all use the same linux-firmware? no matter it's 12.04 or 12.04.5?)

[Adam Lee (adam8157)]

patches for precise have been sent to kernel-team@

[Chris J Arges (arges)]

Hello Po-Hsu, or anyone else affected,

Accepted linux-firmware into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/linux-firmware/1.79.18 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 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 to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

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

[Po-Hsu Lin (cypressyew)]
