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

They work for me. You need to use F6 to select the hw:0 device or the snd_rpi_wsp device. The real problem is that there are well over 400 controls and it is not a realistic option for regular use. Ragnar's scripts are the best bet, atm.

I am half way through writing a Python based simple mixer based on the alsamixer and the amixer programs. It will include the white noise and tone generators as fixed sources, but the current version misses the compressors, high pass and low pass filters and the equalisers.

I build a kernel (make last about 15 hours). After cp the kernel.img in de boot dir. I was able to manupilate alsamixer only once the wolfson audio card. After a reboot I only see the bcm2835 audio . F6 don't show no the wolfson card.
Do I have to configure more things??
