About DM365IPNC Audio control

Hi all：

        Using DM365IPNC program, I had deleted the function of Audio and related function;

  //AUDIO_audioCreate()
//gAVSERVER_UI_config.audioSampleRate = AUDIO_GetSampleRate();
//OSA_tskSendMsg(&gAUDIO_ctrl.audioTsk, pTsk, AVSERVER_CMD_CREATE, NULL, OSA_MBX_WAIT_ACK);
//OSA_tskSendMsg(&gAUDIO_ctrl.audioTsk, pTsk, AVSERVER_CMD_CREATE, NULL, OSA_MBX_WAIT_ACK);
//OSA_tskSendMsg(&gAUDIO_ctrl.audioTsk, pTsk, AVSERVER_CMD_CREATE, NULL, OSA_MBX_WAIT_ACK);

   But when I run system_server like this, it show the following error:

# ./system_server &

I don't know which function will case the ALSA error. Anybody can help me?

    Hi,

    The "amixer" app is called from system_server. This is done to initialize the input audio volume or the input DAC source before AV server starts. You can see that it is being called from ipnc_app/sys_server/src/av_server_ctrl.c

    If you dont want audio at all in the system, you can remove the calls for amixer from the above file.

    Regards,

    Also from the logs it looks like the DDR is set to 243mhz, for dm365 you can run upto 270mhz.

    There are new ubl and uboot available with 2.0, you can upgrade to that.

    you can look at functions setaudioinvolume and setaudiooutvolume to disable amixer call

    Hi:

         Thanks you very much, I have got it.

    #if 0
    SetAudioInVolume(pConfig->audioinvolume);
    SetAudioOutVolume(pConfig->audiooutvolume);
    SetAudioParams();
    #endif

        BTW, I have rebulid ubl, the clock of DDR is update to 330MHz.  Thanks again.
