Wolfson Audio Card and alsamixer

hi,

with the command

alsamixer -c0

it is possible to get access to all paramaters of the card. Is there any documentation available about configuring these parameters (e.g. the use of the 5-band-equaliser)?

The command 'alsamixer' gives access to a GUI with sliders for the Mic Inputs, Equalizers, etc. They don't seem to be active for the Wolfson.

Does anybody know how to set them up?

Thanks

I don't have the card yet, but I hope all settings are exposed in the alsa mixer. The names of controls are pretty the same as those in datasheet, so it is easy to guess what they do.
For some functions you have to first enable them (*_ENA), for some (like EQ) you need to know the coefficients and you need to setup the audio path to actually use it.

For the EQ, check my blog post Wolfson audio paths & how to use EQ and LHPF
