We can play music in a call, not sure what was the use for that, but my android does that too. ni ux for comment.

Comment 2

[Carrie Wang [New account: [e-mail]]]

My Iphone does this too (I can hear the music, but the other side can't), but I can't imagine the use case of the feature. In fact, if the music is playing, it's really impossible to continue the conversation. I'd suggest removing the function or can we ping anyone who planned the feature or knew the background story here? Thanks!

I can't imagine this use case, too. However, maybe there is somebody in the world who likes to play a background music during their conversion...

Dominic, how do you think?

Actually this is an expected behaviour and if I recalled correctly, we have this since v1.x. We didn't change anything and will not I guess, also this is already specified in the sound spec(bug 1068219), the content(Music) channel is able to play during the telephony(Callscreen) channel active, but it only happens when the app with content channel is in the foreground, which means it should be the user brought/launched the app to foreground, so we allow it to play audio.

But I don't know why when the phone gets close to face then it paused the music, I can inveterate this if it blocks something.

Comment 5

[Dominic Kuo [:dkuo]]

And this might be more suitable to put in the AudioChannel Component because Music app does not handle the audio channel things.

Comment 6

[Alastor Wu [:alwu]]

Hi, all,
Is it still a bug issue? As the Comment4, this behavior is allowed from our sound spec.
If user want to play music, we should not prohibit it.

Comment 7

[No-Jun Park [:njpark]]

I think the audio is automatically paused by the proximity sensor when the user puts his/her face close to continue the conversation.  One use case I can imagine is to let the other party hear the music that is currently playing.  

From the comments, it does not sound like it's an issue for anyone (1. it's according to the spec, 2. it does not block the user from performing intended task 3. this bug hasn't been touched for 3+ months) so I'll close it, and if others disagree, it can be reopened.

Hi, park
Accoring to the spec, Music should be abled to be played during a call, but I try to do the STR in comment 0 on iphone6, the music won't stop while we put the devie close to our face, maybe user want to hear the music during a call without headphone or speaker ? May I know your idea?

Hi Alissa, In the sound spec version 1.51 (bug 1068219), on page 12 *1, it says: 

"An active app can decide whether or not to pause sound coming from other inactive apps. An inactive app can decide whether or not to resume when the channel is no longer in use. - FM/Music: Paused and UI disabled during a call. FM/Music resumes after the call."

I think it pauses the music when face is close to the phone because the call app thinks 'channel is in use.' When face is not close to the phone, then it can be assumed that the user is not on call and music is resumed.  If what I think is true, then music should be always paused in speakerphone mode though. (I can't test this right now, but if this is not the case, then we should reopen this bug)

Hi, park
If we launch music and play a song in speakerphone mode, the song can be played in speaker, but if we exit playing page[or screen time out], music will be paused. After entering playing page again, music will continue automatically, the result seems to be the same as that when P-sensor is on: If music playing page is hid during a call, music will be paused.

I'm guessing the phrase "FM/Music: Paused and UI disabled during a call" (from the sound spec) means that 'during a call' is true only when the dialer app is active.  When the music app becames active, then the dialer app will become inactive in turn, and according to the spec the music will be played.  But then again, if I'm in a call on speakerphone mode, wouldn't I always be 'in a call?'  I think UX can make a judgment here, ni?ing tif on this matter to determine whether it's an UX inconsistency or not.  (i.e., whether placing my face close to the phone == music app inactive, AND opening music app deliberately while in a call != during a call)

Comment 12

[Tiffanie Shakespeare [:tif]]

There's a lot of inconsistencies going on here. As pointed out in previous comments, just because dialer app is not in the foreground  (multi-tasking!!) or the phone isn't next to my face (speakphone, putting the phone down for a second, etc) doesn't mean I'm not in a call.

We should determine whether or not to play music while a call is active and implement that consistently rather than trying to guess the user's intent and failing. 

I can imagine this scenario - I'm on the phone and my ear is getting tired so I want to switch sides. I pull the phone away from my face, I do not want music to randomly start playing and then stop again when I put the phone to my other ear.

NI'ing Harly to make the call (no pun intended!) for music to be paused during a call or not.

Thanks!

Comment 13

[Harly Hsu[:harly]]

I think is either we let user listen to music while during a call(should still play music when the phone is next to user's face). Or we don't allow user to play music during the call(disable music controls).

Ni Tori to loop, as she will be the UX owner for audio compete.
