17.8 AT^SAIC Audio Interface Configuration
Description: AT^SAIC configures the interface connections of the active audio mode. The write
command is usable in audio modes 2 to 6 only.
If AT^SNFS=1, any attempt to use the AT^SAIC write command is rejected with and
returns an error reponse. This is because all default parameters in audio mode 1 are
determined for type approval and are not adjustable.
To allocate a specific audio mode to one of the audio interfaces, first select the audio
mode with AT^SNFS and then choose the interface using AT^SAIC.
Note: Only audio interface 1 is supported.

Notes:
• The factory defaults of AT^SAIC vary with the selected audio mode.
If AT^SNFS=1 or 4 or 5, then AT^SAIC=2,1,1.
If AT^SNFS=2 or 3 or 6, then AT^SAIC=2,2,2.
AT^SNFD can be used to reset the factory defaults.
• For use after restart of the ME, you are advised to store the settings of AT^SAIC and AT^SNFS to the audio
profile saved with AT^SNFW. Otherwise, audio mode 1 (AT^SNFS=1) and audio interface 2 (AT^SAIC=2,1,1)
will be active each time the ME is powered up.
• Only audio interface 1 is supported. Always use AT^SAIC=1)
