Re: [alsa-devel] [question] Sample rate IC followed by DAC

I have a sample rate converter IC, which is followed by a DAC. This kind of setup :

SoC chip -> Sample rate conv. chip -> DAC chip

What is the purpose of the converter? What problem does it solve?

How do you construct a machine driver for this setup ?

The original DAC driver will not work correctly, as far as sample rate settings are concerned.

Unfortunately the silicon only supports an older 3.14 kernel.

You mean, you paid for _no support_? And now are asking here instead? (Not that a newer kernel version would help ...)

Well, if your goal isn't a proper driver for upstream, just hack the existing DAC driver to access the other I²C device, when needed.
