Hi Sebastian and Russell,
I tried it on my Cubox (<&si5351 2>), and I have problems with HDMI
output and some audio streams like webradios with sample rates 32 or
22.05 kHz.
According to the Dove specification, the audio controller works with
the samples rates 44.1, 48 and 96 kHz, so, I don't see the usage of the
external clock, except when using the two audio controllers with
different sample rates.
But, BTW, as the kirkwood-i2 driver is written, this last case does not
work: for 44.1, 48 and 96 kHz, the external clock is never used and
there is only one DCO.
