Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::FMRadio, defect, P3)

Description

[Jason Smith [:jsmith]]

Build - 12/18/2013 Leo 1.4

STR

1. Insert headphones into your device
2. Open the FM Radio & start playing a station with sound & enable speaker mode
3. Put FM Radio in background
4. Call the phone with speaker mode active
5. When the incoming call appears, deny the call

Expected

Speaker mode in the FM Radio should resume playback of the FM Radio.

Actual

Nothing happens for a few seconds. Then, FM Radio will resume playback of the sound.

Note - it takes about 5 seconds to resume, which is bit too long.

Hi Pin, 
Is this the resume time of turn on FMRadio?

Apparently this reproduces outside of speaker mode.

I don't think FM radio could be paused/resumed, only could be turned on and off. Everytime the FM radio is turned on will take about 3-4 seconds. Is "turning off the playing-in-background FM radio when a call is coming and turning it back on when the incoming call is denied" a feature be designed? If not, I'm afraid it's a bug we need to find out.

Why can't we pause & resume specifically? Is this a limitation in the design of the FM Radio API?

Adding pause and resume to WebFM API is now one of the improvements proposal, please check bug 942727.

The audio competing between FMRadio and Telephony should be performed by just changing routing path from Device_FM_OUT to others so as I know FMRadio shouldn't have a power on/off transition.

Here's a link to general performance requirements, since "5 seconds is too long" is not really a useful requirement.
