These magic numbers could be replaced by a symbol. I noticed a bunch
in this patch (256 and 256+2), and one more in the GetPropValue patch.

Another magic number here. Maybe instead, max_name_len * 4?

I find this API difficult to understand. At least a comment describing
what 'num' and 'devices' will contain on output would be nice.
If I understand it right, 'devices' will contain 2x'num'
null-terminated strings, right? Another way to represent that is with
a single array of null-terminated strings, with the end-of-array
sentinel being a zero-length string. That eliminates one of the param
fields, and simplifies the array creation and also the iteration side.
You could also split the 'device' and 'name' strings each into their
own arrays, to make the code easier to read.

The usage of "device" and "name" is very confusing in this patch. E.g.
note the 'device' parameter is called with a 'name' argument here, and
the 'name' param is called with 'description'.
Later, in AUDDRV_GetEndpointIDs, we're handling ids and devices and
names. It's pretty mixed up.
Could you use more descriptive terms, more consistently across the
entire codebase? E.g. you could use 'id' for an internal
representation, and 'friendly' for something user-visible?
