Re: please review alsaconf patch

[Martin Habets <errandir_news@mph.eclipse.co.uk>]

Roland,

Thanks for the info. I guess you must have an "audio" device on the
ebus then, and I failed to check for that in my original patch.
Could you try the patch attached in stead of the original one, please?

This patch may also work for the AMD7930, and I would be gratefull if
someone with an AMD7930 could test it.

Thanks,
	Martin
