Yes, A@@0001 is 8329-specific. Thanks for suggestion, it works.

With additional entry, the detection code can be simplified (see patch).

Unfortunately not. Mixer elements enabled by defining ENABLE_SB_MIXER do not
work. I don't know anything about mixer element arrangement in the I/O space.
The 3D and loudness switches have no effect as they're probably supported
only on CMI8330 (that's why it's called CMI8330/C3D).
Add basic support for CMI8329 cards. Makes PCM and OPL3 work.
Does not break CMI8330 (tested).
