!AVCODECSTG
Supporting chipsets (voice-
enabled devices only):
• MDM6200
• MSM6290 (min f/w rev:
K1_0_2_0ap)
• QSC6270 (min f/w rev: S2.0)
Set/report CODEC sidetone gain
Set the CODEC sidetone gain for the specified audio profile. Sidetone gain is the
portion of audio from the microphone that gets routed back to the user’s speaker.
This prevents the user from speaking too loudly by making them aware of the volume
of their own voice.
The gain range is chipset-dependent:
• QSC6270: -96dB to 0dB
• Other chipsets: -84dB to +12dB
This setting is stored in non-volatile memory and persists across power cycles.
Note: (MSM6290, QSC6270) This command has no effect when PCM audio is
being used.
Device-specific details:
• MSM6290 (Firmware revisions K2_0_7_8ap and lower):
• The change takes effect the next time the modem restarts.
• All other chipsets/firmware revisions:
• The change takes effect immediately for the specified profile.
