[alsa-devel] Getting a driver to work

Apologies for asking this old chestnut ... but I have upgraded my busybox/buildroot setup on my Dreamcast and now the AICA driver fails - looks pretty much like a failure to load the firmware. Information on the internet seems rather mixed up and out of date - some of it referring to 2.2 kernels etc...

What is needed to load firmware - is it udev or hotplug (or is hotplug obsolete), and what role do the alsa libs have in all this?

I went through all this two years ago but have forgotten again :(

Thanks

Adrian
