Thanks, the pinmux was not set correctly, and I added the "default". [snip] > What about trying to get 48kHz working first? Does it work with > internal DCO and 48kHz?

How can you have a > different input audio rate tested with 44k1 output rate? The internal dco permits only 44.1, 44 and 96 kHz, so, vlc translates the input rates smaller than 44.1 kHz to 44.1 kHz. > Have you ever tested your audio equipment with something different than > 48k and 44k1 SPDIF PCM?

I have no optical S/PDIF. Well, I did more tests: - i2s or s/pdif input by the tda998x work fine with the internal dco - the pinmux seems correct: device f10b4000.audio-controller state default type MUX_GROUP (2) controlling device f10d0200.pin-ctrl group mpp_audio1 function i2s1/spdifo device f10b4000.audio-controller state default type MUX_GROUP (2) controlling device f10d0200.pin-ctrl group mpp13 function audio1 - I tried both <&si5351 1> and <&si5351 2>, and I get no sound with the external clock. - when running vlc with the external clock, the flux towards the kirkwood driver is blocked and there is no sound interrupt. 47: 0 main-interrupt-ctrl 21 kirkwood-i2s -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
