Hi alsa devels,

Thanks for your suggestions.

Here is the patch for the register default values.
The defaults are chosen for minimal gain settings of the input and output
devices of the CODEC.

If asked for i can send the details of each register.
I will format and send the other patches soon.

The patch is as follows:

[PATCH] Register default values for gain, path selection for various input
and output devices
