Hi,

I am trying to transmit ac3 content via spdif on a mx6 (on a yet non-mainlined driver).

Tried to force non-audio mode via iecset:

# iecset audio 0 control "IEC958 Playback Default" (index -1) not found

Ok, need to pass "-c 1" option to iecset:

$ iecset -c 1 audio 0 Mode: consumer Data: non-audio Rate: 44100 Hz Copyright: permitted Emphasis: none Category: general Original: 1st generation Clock: 1000 ppm root@imx6qsabrelite:/home# aplay -D hw:1,0 -f dat /home/mcxpk_audio_capture.ac3 Playing raw data '/home/mcxpk_audio_capture.ac3' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Thanks,
