For example:
Read:
AT+QAPS=0,4,0
// Read audio parameters of normal audio mode (software channel 0).
+QAPS: 4,0,"96.253.16388.31.57351.31.400.0.80.4325.99.0.20488.0.0.8192"
OK
AT+QAPS=0,4,1
// Read audio parameters of headset audio mode (software channel 1).
+QAPS: 4,1,"96.253.10756.31.57351.31.400.0.80.4325.99.0.16392.0.0.0"
OK
AT+QAPS=0,4,2
// Read audio parameters of loudspeaker audio mode (software channel 2).
