    Audio Uplink Problem

    Hello Developers

    I am creating a thread which has a priority EPriorityLess, in that thread
    I am creating a active object which gives an incoming call event and I want
    to play sound to audio uplink. I am using CMdaAudioRecorderUtility for
    playing sound created as

    iRecorder = CMdaAudioRecorderUtility::NewL(*this, NULL, EMdaPriorityMax,
    EMdaPriorityPreferenceTime);

    Everything works fine if I use it in the App. But Now I want it in the
    background ( recogniser ). Everything works fine .. I get the call event ..
    it playes the sound to the local device specker for 3-4 times ( I am looping
    the sound play ) and then playes to Audio uplink. Isn't it strange?

    If I change that EMdaPriorityMax to some value like 80 or 90, it playes the
    sound only to device specker just once ( No looping this time even if I am
    looping it) and the sound is not played completely. just for 2-3 seconds and
    stops playing it.

    What should be the problem? is it a thread priority issue?

    I am playing sound as ...

    if( iCallStatus == RCall::EStatusAnswering )
    {
    if (!iAudio)
    iAudio = CAudioEngine::NewL();
    iAudio->PlayFileL();
    iLine.NotifyStatusChange(iStatus, iCallStatus);

    }


    Thanks in Advance.

    which phone are you testing this on ?

    Have you checked if the player's call back function is called with an error, when the sound is interrupted ?

    Hi Yucca,

    Thanks for your reply.

    Yes, I already checked the error codes .. its KErrNone. and I am testing it on 7610.

    Anyways .. the problem is solved now. Instead of playing sound from my mdl .. I am playing it from my UI app. It works fine there.

    thanks again.

    Re: Audio Uplink Problem

    Hi Kiran,

    I'm doing a similar application here, I want to make an IVR application, I need to play wav when call active. In 6600, it works well but the wav also played loud in the local speakr (it is suppose to play in the telephony uplink only), but in 6680, the wav could not play through phone uplink, only through local speaker (with tiny voice too)...do you know what's wrong?

    What do you mean by "instead of playing sound from my mdl, i'm playing it from my UI app"

    I already set the device mode into ETelephonyNonMixed, it is supposed to play wav only through telephony uplink, not the device speaker....confusing...or does anyone out there know bout this?? Yucca? please share your knowledge with us....

    Thank you very much

    Re: Audio Uplink Problem

    you could do some searching on this forum, since this issue is addressed in plenty of many posts already. So one more time:

    With OS 6.1 phones, there is usually no problems on playing audio on phone line.

    With 7.0s phones you need to set priority to 80 to be able to play audio to the phone line.

    with 8.0 -> you need to contact your nokia business contact to get special information on how to achieve this functionality.

    With some phones such as 6620 there are HW problems that will prevent usage of this functionality completely.

    Question Re: Audio Uplink Problem

    Thank you Yucca,

    Yes, I have searched the forum about this problem, I've read Symbian known issues too about this problem. I have set the priority to 80 too.

    In the Symbian known issues, it didn't mention that this kind of problem occur in 6680, that's why i'm confused, and the WAV did play in 6680 (but with tiny voice in local speaker)

    I've tried playeradapter too, but failed.

    So Yucca, do you have any idea what's going on? or maybe you could lead me to someone that knows better about this problem?

    Thank you very much
