[meta-fsl-arm] imx-audio not up-to-date?

[Erik Botö]

Hi,

When running the imx-audio setup script on a sabrelite board I get:

root@imx6qsabrelite:~# /etc/init.d/imx-audio start
imx-audio: setting default mixer settings.
amixer: Unable to find simple control 'Playback',0

root@imx6qsabrelite:~#


Does someone have a working set of parameters for amixer that enables
the headphone jack, it was not obvious (too me atleast) how to set it
up. :)

Cheers,
Erik

While the SGTL5000 doesn't have a "Playback" control,
the imx-audio script should be sufficient to set the
volume (via the "Headphone" control).

If the volume isn't sufficient, you can set it manually
like this:

	# amixer sset Headphone "100%"
	# aplay blah.wav

Things should come up at boot time without any calls to amixer.

Are you not hearing any audio?

Please advise,
