Condat audio_Init(): rm setting of sidetone level
The default sidetone level in the absence of audio mode loading
is just that, a basic default without any promises of good tuning.
In the original TCS211 code this default sidetone level was set in
two places: first in L1 init of ABB-via-DSP registers (set to -17 dB),
and then initialized again in Condat audio_Init(), this time set to
-5 dB. The present change removes the redundant second initialization.
The default sidetone level is now -17 dB instead of -5 dB with this
change, but again it is just the default; all serious users are now
expected to use audio mode config files.

State of blobs in FreeCalypso firmware ====================================== FC Tourmaline is almost completely deblobbed. Only the following very small components exist in the form of blobs (prebuilt binary objects for which we have no exact corresponding source) in the standard Tourmaline build: * OSL and OSX glue components of GPF: 14992 bytes of code * TMS470 compiler's RTS library (libc/libgcc equivalent): 13152 bytes of code For OSL and OSX we do have reconstructed C code written based on disassembly of the blobs, but I (Mother Mychaela) do not consider the current state of this C reconstruction to be fit for production use - hence standard Tourmaline fw builds use blob versions of these components. However, our configuration and build system gives you the freedom to select which version of each component you would rather use; the selection is made with Bourne shell config variables on the configure.sh invokation line: OSL=0 use the blob version of OSL OSL=1 use the reconstructed C version of OSL OSX=0 use the blob version of OSX OSX=1 use the reconstructed C version of OSX The current default is OSL=0 and OSX=0. RTS library =========== We do have source code for some versions of the TMS470 compiler's RTS library, but they may not be exactly corresponding to the blob version from TCS211 which we are using. This area is deemed to be such a low priority that no real investigation has been done yet.
