Headset buttons sometimes not working, double tap at the same time, too.

[piwats]

Headset controls (buttons) for volume up/down sometimes stop working.

Coincidentally, double tap stops working at the same time.

When I turn on the display by the power on button, and reconnect the headset again, all is fine and everything seems to work again.

This odd behaviour I haven't seen in CM12.

I guess that double tap and headset controls are controlled by input, so this is the way to go. I'll try to logcat/dmesg it, if possible.

This is on cm-13-20160131.

I have a way to reproduce it:

Prerequisites:

turn off music player, headset not inserted.

insert headset.

Action 1: Volume Up:

logcat:

02-01 16:50:22.774  1138  1411 I vol.Events: writeEvent active_stream_changed STREAM_RING
02-01 16:50:22.776  1138  1411 I vol.Events: writeEvent key STREAM_RING 5
02-01 16:50:22.784  1138  1138 I vol.Events: writeEvent show_dialog volume_changed keyguard=false
02-01 16:50:22.922  1688  1688 D EmojiAltPhysicalKeyDetector: onKeyUp() : KeyEvent { action=ACTION_UP, keyCode=KEYCODE_VOLUME_UP, scanCode=258, metaState=0, flags=0x8, repeatCount=0, eventTime=1484501, downTime=1484341, deviceId=2, source=0x101 }
02-01 16:50:22.922  1688  1688 D EmojiAltPhysicalKeyDetector: onKeyUp() : Not Mapped: 24
02-01 16:50:25.782  1138  1138 I vol.Events: writeEvent dismiss_dialog timeout
02-01 16:50:25.784  1138  1411 I vol.Events: writeEvent active_stream_changed UNKNOWN_STREAM_-1

Action 1 result: Volume goes up. (Telephone symbole and volume shifter are shown)

Action 2: Middle button/pause or call button:

02-01 16:53:49.922  1688  1688 D EmojiAltPhysicalKeyDetector: onKeyUp() : KeyEvent { action=ACTION_UP, keyCode=KEYCODE_HEADSETHOOK, scanCode=256, metaState=0, flags=0x8, repeatCount=0, eventTime=1691501, downTime=1691311, deviceId=2, source=0x101 }
02-01 16:53:49.922  1688  1688 D EmojiAltPhysicalKeyDetector: onKeyUp() : Not Mapped: 79

Action 2 result: Nothing happens.

**Action 3: Volume down:***

Pressing the volume down button results in no action in logcat. However dmesg gives this out:

[ 1644.644592] arizona 1-001a: Failed to get valid MICDET value
[ 1645.364963] arizona 1-001a: Failed to get valid MICDET value
[ 1645.694965] arizona 1-001a: Failed to get valid MICDET value
[ 1645.983800] arizona 1-001a: Failed to get valid MICDET value
[ 1646.404150] arizona 1-001a: Failed to get valid MICDET value

This is logged every time the volume down button is pressed.

Now I start the built in music player. No music is played at this moment.

Action 1: Volume Up: Music volume goes up (A note symbol with a shifter is shown)

Action 2: Pause button: nothing happens A long pressing of this button results in this in dmesg:

02-01 17:04:36.033   741  1718 I ActivityManager: START u0 {act=android.speech.action.WEB_SEARCH flg=0x10800000} from uid 1000 on display 0

Action 3: Volume down: nothing happens However a long pressing on the volume down button results in this in dmesg:

[ 2269.713889] arizona 1-001a: Button level 64 out of range

Now I let the player play a music track.

Action 1: Volume Up: works.

Action 2: pause: nothing.

Action 3: Volume Down: suddenly it starts to work. Logcat:

02-01 17:07:52.156  1138  1411 I vol.Events: writeEvent level_changed STREAM_MUSIC 4
02-01 17:07:52.161  1138  1411 I vol.Events: writeEvent active_stream_changed STREAM_MUSIC
02-01 17:07:52.163  1138  1411 I vol.Events: writeEvent key STREAM_MUSIC 4
02-01 17:07:52.174  1138  1138 I vol.Events: writeEvent show_dialog volume_changed keyguard=false
02-01 17:07:52.183  1688  1688 D EmojiAltPhysicalKeyDetector: onKeyUp() : KeyEvent { action=ACTION_UP, keyCode=KEYCODE_VOLUME_DOWN, scanCode=261, metaState=0, flags=0x8, repeatCount=0, eventTime=2533761, downTime=2533571, deviceId=2, source=0x101 }
02-01 17:07:52.184  1688  1688 D EmojiAltPhysicalKeyDetector: onKeyUp() : Not Mapped: 25
02-01 17:07:53.668  1138  1138 I vol.Events: writeEvent dismiss_dialog timeout
02-01 17:07:53.669  1138  1411 I vol.Events: writeEvent active_stream_changed UNKNOWN_STREAM_-1

Now, if I disconnect the headset and connect it again, the very same behavior comes up, that is the volume down button doesn't work, the arizona 1-001a: Failed to get valid MICDET value error can be seen in dmesg, and if you start the steps from playing music all over you should get the idea, it repeats.

[piwats]

In recent builds double tap seems to work without any flaws. Thus I have to assume the problems with double tap were upstream related.

[piwats]

seems to be somehow fixed by upstream.

closing :)
