18.15 AT^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.
