audio issue with custom i.MX6 board (TLV320)

[smaschy]

Hey Community, i'm working with a custom board based on an i.MX6 SoC from Phytec. My Problem is that i get no audio output from the headphone or speaker channel of the used TLV320AIC3007. Does somebody has any idea for me?

If i try to play an example audio file (1) i get this error (2) or if i try the speaker-test (3) i get the next error (4).

gst-play-1.0 gag.mp3
(gst-plugin-scanner:239): GLib-GObject-CRITICAL **: g_object_class_install_property: assertion 'class->set_property != NULL' failed

Hi smaschy

please check if clocks are present with oscilloscope and look at

imx6 - tlv320aic32x4 codec no data on I2S port 

Best regards
