I'm using the tlv320dac23 device in usb master mode. The data format is DSP format and 'fs' selected is 32 Khz.
I feed the device with MCLK = 12 MHz.
I set and send the following control register:
- x"0000" (left line input).
- x"0200" (right line input).
- x"047f" (left channel headphone volume control).
- x"067f" (right channel headphone volume control).
- x"0812" (analog audio path control).
- x"0c07" (power down control).
- x"0e43" (digital audio interface format).
- x"1019" (sample rate control.
- x"1201" (digital interface activetion).
my DSP send data steps of 1 Khz tone for each 'LRCIN' pulse according to the data sheet requirement.
still no audio come out from the headphone.
please advice?
