Hi Sir,

 

We tested SPDIF OUT via TOSLINK SPDIF connector on i.MX6SDP board. (GPIO_17)

We measure i.MX6 SPDIF OUT pads have waveforms to work (red light is bright at TOSLINK SPDIF connector)

But it is not sound by headphone on LINDY SPDIF hardware.

 

LINDY spdif transform box information:

 

support freqence : 32 ~ 192KHz

support format : spdif, 24bit 2CH LPCM

input interface : TOSLINK

 

Below are test command :

 

aplay -D plughw:1,0 -N -M naim-test-2-wav-24-96000.wav

Playing WAVE 'naim-test-2-wav-24-96000.wav' : Signed 24 bit Little Endian in 3bytes, Rate 96000 Hz, Stereo

 

aplay -D plughw:1,0 -N -M big_441_24bit_2.wav

Playing WAVE 'big_441_24bit_2.wav' : Signed 24 bit Little Endian in 3bytes, Rate 44100 Hz, Stereo

 

root@freescale /wav$ aplay -l
