[alsa-devel] Transmitting ac3 content via spdif

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

root@imx6qsabrelite:~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sgtl5000audio [sgtl5000-audio], device 0: HiFi sgtl5000-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: imxhdmisoc [imx-hdmi-soc], device 0: IMX HDMI TX mxc-hdmi-soc-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0

Transmitting a wav file works fine though.

Any suggestions as to how provide the "IEC958 Playback Default" control?

Thanks,

Fabio Estevam
