I am using dm368 external aic3x codec to play and record, so i opend a capture and a playback device. whis the proposal of http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/p/138908/716905.aspx#716905
i chaged NUM_CHANNELS to 2,and capture device is runing,and can receive data from aic3x, but when i close the audio device, an error occurred as 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 ?
