As noted in a previous commit, the E-MU Digital Audio System cards don't try very hard to be Sound Blasters. This commit takes it further and introduces a module option to switch to a completely separate mode.
In that mode: - The regular PCM playback/capture devices are removed - The EFX playback/capture devices get index 0 - Consequently, the regular mixer controls are also completely removed. This is no real loss, given the expected use with a sound server. - The voice send routing+amount & attenuation controls are also removed, as they are just another mixer. The routing is redundant with the FPGA channel routing, and amounts/att'n can be done in software. The latter are also incompatible with 32-bit playback, which we'll add support for later. - A_EXTOUT is now also free for multi-channel capture, so we use that instead of A_FXBUS2 - this will later simplify using both at once. - For the same reason, the FX outputs are not listed in /proc anymore - The device name is changed, so mixer settings don't get mixed up
This continues the pre-existing design with a single multi-channel device where the channels are routed by manual mixer controls from/to the physical ports. De-/multiplexing must be done by the sound server if independent streams are to be used.
An alternative design would be exposing each physical port as a separate device and automatically setting up the routes. This would be a somewhat radical departure from the status quo, and I don't know whether it would be a net benefit. It certainly would be harder to implement, as it would require sync start of streams and a channel allocator (the latter would have the added benefit of properly reporting EMU32 & EDI bus over- allocation, which the mixer does not). There is only one big multi- channel capture engine, so streams would have to be de-multiplexed by the driver in software - which seems a bit counter-productive if the sound server would re-multiplex them again.
