Comment 1 Vivien Nicolas (:vingtetun) (:21) - (NOT reading bugmails, needinfo? please) 2013-01-15 07:06:12 PST
It seems like this happens on every second launch of the application. I have this error in the console when the application is closed manually in the cards view:

E/GeckoConsole(  107): [JavaScript Error: "FMRadio message DOMFMRadio:getPowerState from a content process with no 'fmradio' privileges." {file: "resource://gre/modules/DOMFMRadioParent.jsm" line: 400}]
Comment 2 Randy Lin [:rlin] - Be Mozillian on 2015/01/26 2013-01-15 18:04:20 PST
Do you press the play button when after
1. open the fm app
2. plug-in headset
I found I need to press the play button and the fm radio works well. 
test on 1/15 mozilla-b2g18-unagi-eng 	15-Jan-2013 08:01 build.

*** Bug 831053 has been marked as a duplicate of this bug. ***
Comment 5 Marco Chen [:mchen] 2013-01-17 00:40:09 PST
In Bug 823798, it also modified for adding "". This will disable FM in analog mode in default so this bug should not be happened.

And this new property is stored at /system/build.prop so if you just update your phone via OTA then it just for gecko only. Please flash an entire newest system.img for that new property.
Comment 6 mlevin 2013-01-17 10:05:28 PST
Reproduced this issue on OTA Unagi to build 20130117070201, Kernel Dec 5. Was able to hear FM Radio the 1st time, then unplugged headset, then plugged it back in and reopened FM Radio and could not hear anything.

Hi Michael, 
I found the []: isn't include in b2g-18 nightly build on (17-Jan-2013 07:55)
As test with mchen and me, it seems need to clean build to fix this problem. Could you help to check?
Comment 8 Andrew Overholt [:overholt] 2013-01-18 10:37:10 PST
Randy, it looks like bug 823798 has landed the pref on b2g18.

Philikon, can you lend a hand here?
Comment 9 Randy Lin [:rlin] - Be Mozillian on 2015/01/26 2013-01-20 18:08:21 PST
compare with the  latest image, the []: [true] attribute is setting correctly and can't find this issue. But After checking the pvtbuild nightly one, the build.prop can't find this property, so as in device. Do the clean build in the pvtbuild build machine may helpful for this issue.

Comment 11 Joe Cheng [:jcheng] 2013-01-21 00:45:37 PST
perhaps :hwine can provide some help here?
Comment 12 Andrew Overholt [:overholt] 2013-01-21 10:27:14 PST
Chris Atlee can probably provide more info on the builds.
Comment 13 Chris AtLee [:catlee] 2013-01-21 13:42:52 PST
where in the build process should this pref be getting set? I can't find it in any of our builds.

can you give me the url of the build that you think has this pref set properly?
Comment 14 Randy Lin [:rlin] - Be Mozillian on 2015/01/26 2013-01-21 17:49:34 PST
1. This ROM on this url: is set correctly.

Can you fine this change on the "device/qcom/unagi" git Repository?

Comment 15 Naoki Hirata :nhirata (please use needinfo instead of cc) 2013-01-22 11:59:23 PST
To note when you get an incoming call, it also stops the radio from playing.  Not sure if this is related or a separate bug.
Comment 16 Naoki Hirata :nhirata (please use needinfo instead of cc) 2013-01-23 15:24:57 PST
Created attachment 705604 [details]

I see : 01-23 09:54:08.617: W/AudioFlinger(118): Thread AudioOut_1 cannot connect to the power manager service

Just wondering, didn't the audio go on a different channel now?  Or is that only for the music app?
Comment 17 Randy Lin [:rlin] - Be Mozillian on 2015/01/26 2013-01-24 02:30:04 PST
Hi Hal,
Test on
<full_unagi-user OPENMASTER eng.cltbld.20130124.020958 test-keys>
Still can't find the ""
Does the Bug 833410's fix land?
Comment 18 Andrew Overholt [:overholt] 2013-01-24 10:34:25 PST
If we get a new build from releng before rlin gets to the office, can you verify the fix, Naoki?

qawanted:  verify analog path pref fixes this bug
Comment 19 Naoki Hirata :nhirata (please use needinfo instead of cc) 2013-01-24 10:58:12 PST
Feed me!  ;)
Comment 20 Naoki Hirata :nhirata (please use needinfo instead of cc) 2013-01-24 11:01:09 PST
Oh and mark this needinfo on me again... I'll look at it asap.

Correct - the change was only landed at  2013-01-24 12:57:06 PT (see bug 833410 comment 7)

Only builds started after that will use the new gonk with the requested changeset.
Comment 23 Naoki Hirata :nhirata (please use needinfo instead of cc) 2013-01-24 16:48:05 PST
Hrm.  This is fixed now with the build:

- not having headset in and playing fm radio : message (as expected)
- plugging in headset and hit play : played radio through headset
- stopping fm radio : stopped
- started fm radio again : started up again ( slight delay ) **
- plugged out headset : stopped radio
- plugged in headset : started radio again
- gave a call : ringing sounded not through headset but through speaker; voice was through headset  ** need to report a bug
- ended call : fm radio played 
- quit fmradio through task manager : fm radio stopped
- started fmradio : fm radio played again (didn't memorize last location)
- placed radio in background : conintued to play
- unplugged headset : fmradio stopped
- plugged in headset : fmradio played 
- loaded music, played a song : fmradio stopped, music played
- stopped music : fmradio started playing
- played music again, waited til it hit the next song : ** music didn't go to the next song, fmradio played.
- played video : fm radio stopped while video played, fm radio started when it ended
went to camera, capture video : fm radio stopped completely even after finishing recording.  there was a crash that occurred not sure exactly what.  ** need to report a bug.
- launched browser, went to youtube, played a youtube vid: fm radio stopped, video played
- stopped youtube : fm radio continued
- set alarm : fm radio stopped... alarm sounds through speaker not headset... **
- closed alarm : fm radio started
- set alarm again, used snooze : after hitting snooze, fm radio started again.
- turned on all sounds in settings including keyboard typing, went to email,  composed an email : typing sounds go through headset while fm radio is playing; no email send sound like on uxbranch... is that a bug?
- snooze went off : fm radio stopped and when closing the alarm, fm radio started
- went back to browser, and went to : fmradio plays over  **
- : grooveshank : fm radio plays over grooveshark at the same time ** 
- unplugged while both were playing : fm radio stops, grooveshark still plays.

That was all in about 30 minutes of testing; session based.
Comment 25 Naoki Hirata :nhirata (please use needinfo instead of cc) 2013-01-24 16:49:22 PST
probably would have been faster if I wasn't documenting.  :)
Comment 26 Naoki Hirata :nhirata (please use needinfo instead of cc) 2013-01-24 17:22:28 PST
bug 796872 is fixed; bug 816118 maybe fixed?; bug 814054 is fixed; bug 817456 is fixed; bug 831481 seems fixed; bug 833989 seems fixed

bug 825817 <- noted the pause in this bug.
bug 830208 <- may have been my crash
Bug 834527 - incoming call rings through speakers instead of headset. 
Bug 834529 - [Music] If FM Radio is playing and you play a song in the music app, music app will not go to the next song
Bug 834532 - [Clock] Alarm does not play through headset
the last 2 are probably the same as bug 796514 where it's the web audios that keep playing...
Bug 834535 - FMradio beeps when you close it from the task manager
Comment 27 Andrew Overholt [:overholt] 2013-01-25 13:08:33 PST
Andrea/Marco, can you help Naoki sort out these issues?
Comment 28 Randy Lin [:rlin] - Be Mozillian on 2015/01/26 2013-01-27 22:15:31 PST
Test and verify on 1/27 pvt builds. The analog property is set on the ROM image  correctly. Change the status to fix ready.

  Not related to the build issue here. 

bug 816118 maybe fixed?; 
  It is invalid and not related to the build issue here.

> bug 814054 is fixed; 
  The report on comment 20 of 814054 should be fixed as Randy said here.
  But the original issue from 814054 is not fixed yet.

> bug 831481
  Fixed by the build issue here.
Comment 30 [:onecyrenus] 2013-01-31 02:13:07 PST
