Re: [ANNOUNCE] headset-control : Make the headset button actually manipulate tracks.
 

That would explain why my usage of inotify-tools didn't help much...

thp uses a GIOChannel to monitor /sys/devices/platform/gpio-switch/headphone/state and headphoned sleeps for most of the time so I guess using one to monitor the file cb42 told us about wouldn't do any harm...

@jaeezzy, that's a good idea. Will come up with logical ways to handle that one

There's a brainstorm about this also: http://maemo.org/community/brainstor..._input_reader/

Re: [ANNOUNCE] headset-control : Make the headset button actually manipulate tracks.
 

I hacked a bit on the headphoned code adding another watch for the file /sys/devices/platform/nokia-av/detect but it doesn't detect any change

Then I've tried with inotifywait for both files /sys/devices/platform/nokia-av/detect and /sys/devices/platform/gpio-switch/headphone/state
I've been surprised to see that a change is detected only for the latter. So I think there's no other way than polling the file.

Indeed. Nokia's ****ish behaviour regarding this is pissing me off. I'm tempted to upload a nokia-av.ko file that doesn't disable the button.

I've figured out what happens: When inserting a headset, /usr/lib/ohm/libohm_accessories.so will register it to the system as plain headphones. Plain headphones do not have a button, so why would pressing it do anything? When the policy changes to "phone", this file will re-register the headset as a - *gasp* - headset; this is why (if you monitor HAL) you "see" the headphones being "removed and reinserted".

Making a replacement /usr/lib/ohm/libohm_accessories.so that would register the headset in the first place as a headset wouldn't be hard work (riiiight...) thanks to IDA Pro and the examples of plugins found in the OHM package but there's no point when you can just modify nokia-av.ko to not disable the button, which is what I will be doing soon. **** you, Nokia, and your stupid decisions.

Re: [ANNOUNCE] headset-control : Make the headset button actually manipulate tracks.
 

Yeah, that's what I thought of doing originally, but then after playing around a bit more (my kernel hacking knowledge is pretty much limited to printk's) I realized that all sysfs does is call a relevant piece of code in the driver, that value doesn't exist until you actually read it.

I looked over nokia-av.c and I probably missed the code that actually handles the disabling... I ended up wading through twl-madc before eventually going to bed. It would be awesome to finally be able to use the damn button... Good luck :)

Hi:

I am completely new at this, but I would like that when I press the button of the headset, the song changes (instead of pause it)... how can I do this?

Any help would be appreciated...

Thanks!

Re: [ANNOUNCE] headset-control : Make the headset button actually manipulate tracks.
 

At the moment, it is impossible to even get events from pressing the button, so it can't be done at the moment (not even pausing). Unless you have an N810 / N800.

Re: [ANNOUNCE] headset-control : Make the headset button actually manipulate tracks.
 

This only works on the standard black inear headset (with the white plugs)

It does not work with the AD-43 & HS-45 Stereo Headset, then it returns 0 :confused: I'd do anything to help with this issue. Unfortunately i have no experience in linux kernel programming. :(

Re: [ANNOUNCE] headset-control : Make the headset button actually manipulate tracks.
 

any luck with this ?

Re: [ANNOUNCE] headset-control : Make the headset button actually manipulate tracks.
 

Oh, yes, baby; you bet your *** there's progress!

Here's how to enable it:
Open the file /usr/share/policy/etc/current/alsaped.conf and replace "jackbias-off = jack-bias: off" with "jackbias-off = jack-bias: on"; reboot and watch the System bus.

I will be uploading an "enabler" package to extras-devel later on today along with a quick daemon that pauses/plays a track in the Media Player. Ultimately, if thp allows it, I'd like to get it into headphoned but thp uses libdbus and I like dbus-glib...
