18.15AT^SNFS Select audio hardware set

The AT^SNFS write command serves to set the audio mode required for the connected equipment.

AT^SNFS can also be used in conjunction with AT^SAIC. This is useful, for example, if the audio interfaces are operated alternatively to benefit from different devices. Each audio mode can be assigned a specific interface. To do so, first select the audio mode with AT^SNFS, then activate the audio interface with AT^SAIC and finally enter AT^SNFW to store the settings to your audio profile. To switch back and forth it is sufficient to use AT^SNFS.
