Set/report volume for each voice volume level in Rx direction
Set the volume for each OTA (over the air) voice ‘volume level’ in the Rx direction.
Volumes range from -50 dB to 12 dB and are applied to PCM voice packets after
they have been decoded by the vocoder.
The setting is stored in non-volatile memory and persists across power cycles.
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.
