After MO is connected, auto play an audio.
how to implement: auto play an audio to remote mobile phone?[em01]

Which platform do you work on?

bowringshine · 发表于 2009-9-15 08:27:44

MTK![em07]

eastvenuslee · 发表于 2009-9-15 09:15:44

Easy,you can play an audio when you accept a call.
Key words:gAcceptIncoming

ths, eastvenuslee!

Good question! But the answer was rather bad! You should know something about PCM! That's the solution! You know, not only the music ,either the background noise would be transmit through the mircophone!

Maybe you can give us a better answer!
We wait your rather good answer ……Pls,dollfacedboy!

solution 1: after mo call is connected, play audio in loud speaker to make MIC can get sound.
solution 2: after mo call is connected, make audio output to baseband(hardware must support line switch between mic and audio output)

Excellent at 8th Floor:good idea!
Hi bowringshine,Which mtk platform do you work on?
If you work on MT6226,I suggest you use the second option.

bowringshine · 发表于 2009-9-16 15:31:57

MT6223

eastvenuslee · 发表于 2009-9-16 16:49:26

Oh, I am wrong:play audio in loud speaker,not receiver.
You can try any one of the two methods. [em01]

dollfacedboy · 发表于 2009-9-16 22:37:03

I told you the solution! First,you may get a baseband datasheet of mtk series. And then search "PCM". Read the reference,and you'll get a figure about the solution! Well, how to figure it out! You know, the analog audio signal were convert to digital signal and tansmit after encoding! So, I'm sorry to say that none of your solutions works! A clue for you is that you should skip the a/d convert! It's not a easy work if you know nothing about the intermedia layer which include audio and other media decode/encode procedure! Oh my god, I talked too much about the topic, God fogive me![em14]

这个论坛的都说洋文啊。厉害厉害。

如果是26,27平台，可能要从硬件上下功夫，做一个从音频输出到MIC输入的可控通路；
其他平台应该可以通过软件实现，
打开 1) BACKGROUND_SOUND　＝　TRUE
2) 如果是比较新的版本的话，查找__MMI_AUTO_ANSWER_MACHINE__，估计就差不多能实现你说的功能了。

eastvenuslee · 发表于 2009-9-18 14:46:58

__MMI_AUTO_ANSWER_MACHINE__ 答录机？
我在26平台上做的时候碰到这个问题——播放提示音时没声音……

bowringshine · 发表于 2009-9-18 18:10:01

我现在就打算参考一下 BACKGROUND_SOUND 来完成
