[Dell Latitude E5550] Microphone mute key does not work on this system

This change was made by a bot.

OEM project bug: LP #1284036.

I'm not familiar with the hotkeys, just a bit with the LEDs that could be physically located on them. Could you reassign to a hotkey expert perhaps?

Please install this dkms and test again.

After add the " /etc/udev/hwdb.d/60-dell-mic-mute-hotkey.hwdb" and update the database, the mic mute hotkey can work.

The above dkms (in the comment #5) is for fixing the mic mute led problem. Please test it.

And about this problem "(Also the icon is not correct, which show a speaker instead of a mic)", it seems this is a unity-settings-daemon's bug. After apply the patch below, the problem disappeared.

Hello Hui,
the DKMS file you provided here could not make the LED work.

Steps:
1. Create an entry at /etc/udev/hwdb.d/60-dell-mic-mute-hotkey.hwdb with the following content:
# Dell platform kernel driver
keyboard:name:Dell WMI hotkeys:dmi:bvn*:bvr*:bd*:svnDell*:pn*
 KEYBOARD_KEY_150=f20 # Mic mute toggle

2. Update it with
sudo udevadm hwdb -u

3. Install the DKMS file provided in comment #5

4. reboot and test the mic mute key.

Please test this dkms, let us see if the led problem can be fixed by this dkms.

in this dkms, I use SND_PCI_QUIRK(0x1028, 0x062c, "Dell", ALC293_FIXUP_DELL_WMI_MIC_MUTE_LED) to fix the mic led problem.

Hello Hui,
The new DKMS file you provided in comment #9 could make the mic LED work.
Thanks!

    ALSA: hda - fix the mic mute led problem for Latitude E5550

    The microphone mute led on the Latitude E5550 can't work. We need to
    apply DELL_WMI_MIC_MUTE_LED quirk to this machine.

    The machine uses alc293 codec and already applied the quirk
    ALC293_FIXUP_DELL1_MIC_NO_PRESENCE through pin_fixup_tbl[].

    Here we just let DELL_WMI_MIC_MUTE_LED be chained to
    ALC269_FIXUP_HEADSET_MODE, then the machine will have these
    quirks ALC293_FIXUP_DELL1_MIC_NO_PRESENCE-->
    ALC269_FIXUP_HEADSET_MODE-->ALC255_FIXUP_DELL_WMI_MIC_MUTE_LED.

    ALSA: hda - move DELL_WMI_MIC_MUTE_LED to the tail in the quirk chain

    We have one more Dell machine needs DELL_WMI_MIC_MUTE_LED quirk, but
    the machine uses alc293 instead of alc255. So if
    DELL_WMI_MIC_MUTE_LED still chain ALC255_FIXUP_DELL1_MIC_NO_PRESENCE,
    the machine can't use this quirk.

    To change this situation, let the DELL_WMI_MIC_MUTE_LED to be a
    standalone quirk, and let other quirks chain it.

    After this change, this quirk can be chained to any existing quirks,
    and as a result, it is possible that this quirk is applied to
    a non-Dell machine or a Dell machine without mic mute led on it, but
    it is still safe since alc_fixup_dell_wmi() will return an error in
    these situations.

    And remove the quirk for machine with subsystem id 0x6010 and 0x601f,
    these two machines will fall back to the quirk
    ALC255_FIXUP_DELL1_MIC_NO_PRESENCE-->ALC255_FIXUP_HEADSET_MODE-->
    ALC255_FIXUP_DELL_WMI_MIC_MUTE_LED through pin_fixup_tbl[].

Hi Po-Hsu,

And about the icon problem, when you press mic mute hotkey, the osd shows the speaker icon instead of microphone icon, i think this is a bug for unity-settings-daemon, and the patch in the comment #7 can fix it.

Please open a unity-settings-daemon bug to track this problem and involve the desktop development team in.

@Hui, can you also SRU the U-S-D patch?

Still waiting it, please refer to the email below:

Hello Seb,

The option 2 is fine, it is best that two fixes to be SRUed together.

Thanks,
Hui.

@Hui, sorry for the delay, I'm doing a SRU of that change to trusty

@Sebastien, Thank you very much, I have an OEM bug (#1414553) still waiting this change.

Hello Po-Hsu, or anyone else affected,

Accepted notify-osd-icons into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/notify-osd-icons/0.8+14.04.20151016-0ubuntu1 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!

Verification failed. It seems we need to fix this problem not only in notify-osd-icons but also in unity-settings-daemon.

The steps I performed verification as below:

I Installed 14.04.3 LTS to a lenovo laptop
enabled -trusty-proposed source from Software&Updates
run Software Updater to update all packges
run dpkg --list to check notify-osd-icons, this package is not updated
download the this package from https://launchpad.net/ubuntu/trusty/amd64/notify-osd-icons/0.8+14.04.20151016-0ubuntu1
manually install it
run dpkg --list to verify this package is installed
reboot
test microphone mute, the osd icon is still speaker rather than microphone.

So it looks like we need to upgrade the unity-setting-daemons for trusty as well.

Hello Po-Hsu, or anyone else affected,

After install the unity-settings-daemon_14.04.0+14.04.20151012-0ubuntu1_amd64.deb on a lenovo machine, reboot, then test the microphone mute hotkey, the OSD icon is correct (now it is microphone icon, then it is speaker icon) now.

So the unity-settings-daemon_14.04.0+14.04.20151012-0ubuntu1_amd64.deb fixed the problem on trusty.

change the verification-needed to verification-done-trusty
