According to the device-tree, it seems to be a snapper (tas3004),
maybe we don't set some i2s registers properly, I don't know.
The device-tree also imply that it supports 2 sample rates,
it's possible that the sample rate or format on i2s side doesn't
match what is configured in the texas chip.

The remaining problem seem to be the same as desktop r9000's with ADC
connector, that is a palette issue. According to Ani, the DACs are
physical (that is, regardless of CRTC1 or 2 usage, the DACs for each
output is fixed, and we may not be configuring the palette in the
proper one).
