Issue on AIC codec with IPNC V2.6

hi,

I really thanks for your sharing. Do you have some experiences to the AIC audio gain? By this modification, the audio worked but the audio volumn adjustment may not affect.

Thank you so much!

You can change the audio volumn of left and right channel as below.

<audio in>

amixer -c 0 sset 'Left MIC to Left Input',0 100%

amixer -c 0 sset 'Right MIC to Right Input',0 100%

<audio out>

amixer set 'PCM' 100%

hi TaeHo Kim89108, I met the same problem with bioz ,Under your proposal,I changed NUM_CHANNELS to 2, audio data can be reiveived, but there is a new problem. When I delete audio task,there is an error below: Alignment trap: av_server.out (568) PC=0x401aba28 Instr=0xe591300c Address=0xfec 77b47 FSR 0x001 and once the error occored, I cann't begin audio task again. Is there someting else to be changed except NUM_CHANNELS ? In this program, i opend a capture and playback audio device, is that playback device caused this problem? NUM_CHANNELS of playback device should be set to 1 or 2?

hi, Pen Zeng1

Did you delete the audio task except the video task?

I think the problem is memory reference error...but I don't know why right now.

I will reply to you if I find a solution.

Good luck..!

You're welcome.. late reply..

I'm a Korean. But I live in Daejeon :D

Thank you for your kindness.

Good luck~!

I have just gone to Boryeng Mud festival last weekend :).

Glad to know you and hope to see you one day.

Hi,TaeHo Kim89108

When I run 

OSA_tskSendMsg(&gAUDIO_ctrl.audioTsk, pTsk1, AVSERVER_CMD_CREATE, NULL, OSA_MBX_WAIT_ACK); nad 

OSA_tskSendMsg(&gAUDIO_ctrl.audioTsk, pTsk1, AVSERVER_CMD_START, NULL, OSA_MBX_WAIT_ACK);

to create and start audio task, the capture device is running, but when i DELETE the audio tast,that is

OSA_tskSendMsg(&gAUDIO_ctrl.audioTsk, pTsk1, AVSERVER_CMD_DELETE, NULL,OSA_MBX_WAIT_ACK);

an error occored as below:

AUDIO: Received CMD = 0x0301

AUDIO: Delete...
AUDIO_audioTskDelete
*** glibc detected *** ./av_server.out: free(): invalid next size (normal): 0x00380d28 ***

And I print the  gAUDIO_ctrl.inputBuffer pointer which is created by AUDIO_audioTskCreate() the pointer value is just 0x00380d28.

The video task is allways running when start up and not closed.

int AUDIO_audioTskCreate()
{
int ret = OSA_EFAIL;
DRV_AudioConfig Audioconfig;

Audioconfig.deviceId = 0;
Audioconfig.numChannels = NUM_CHANNELS;
Audioconfig.samplingRate = SAMPLE_RATE;
Audioconfig.buff_Of_Samples = NUMSAMPLES;

ret = DRV_audioOpen(&gAUDIO_ctrl.audioHndl, &Audioconfig);
if( ret != OSA_SOK )
{
return ret;
}

gAUDIO_ctrl.streamId = ALG_AUD_CODEC_G711;
gAUDIO_ctrl.encodedBuffer = (short *)OSA_cmemAlloc(ENCODEDBUFSIZE,32);
if (gAUDIO_ctrl.encodedBuffer == NULL)
{
OSA_ERROR("Failed to allocate encodedBuffer\n");
return OSA_EFAIL;

}

/* Allocate input buffer */
gAUDIO_ctrl.inputBuffer = OSA_memAlloc(INPUTBUFSIZE);
if (gAUDIO_ctrl.inputBuffer == NULL)
{
OSA_ERROR("Failed to allocate input buffer\n");
return OSA_EFAIL;
}
return OSA_SOK;
}

int AUDIO_audioTskDelete()
{
DRV_audioClose(&gAUDIO_ctrl.audioHndl);
if( gAUDIO_ctrl.inputBuffer )
{
OSA_memFree(gAUDIO_ctrl.inputBuffer);
}

if( gAUDIO_ctrl.encodedBuffer )
{
OSA_cmemFree((Uint8 *)gAUDIO_ctrl.encodedBuffer);
}

return OSA_SOK;
}

hi， I am working with DM368 IPNC. We are using V2.6 software，to. For your change we modified ehe kernel config as yours，and change NUM_CHANNELS from 1 to 2，but the record is wrong . My MCLK is from CLKOUT1，24MHZ，MIC in use MIC2. Can you tell me where am I wrong???
