1. Headset analog gain:

   Enable/Disable:

   echo on/off > /sys/kernel/wcd9320/headset/hplana_gain echo on/off > /sys/kernel/wcd9320/headset/hprana_gain

   Gain: Max=0 Default=5 (Lower is louder)

   echo 5 > /sys/kernel/wcd9320/headset/hplana_gain echo 5 > /sys/kernel/wcd9320/headset/hprana_gain
2. Headset digital gain:

   Enable/Disable

   echo on/off > /sys/kernel/wcd9320/headset/hpldig_gain echo on/off > /sys/kernel/wcd9320/headset/hprdig_gain

   Gain: Default=0 , Don't set this value too high, 24 is the maximum recommended

   echo 16 > /sys/kernel/wcd9320/headset/hpldig_gain echo 16 > /sys/kernel/wcd9320/headset/hprdig_gain
3. Speaker on/off:

   You can turn off speaker only instead of muting all sound in system.

   echo off > /sys/kernel/wcd9320/speaker/spkdrv_on
4. Speaker digital gain:

   Enable/Disable

   echo on/off > /sys/kernel/wcd9320/speaker/spkdig_gain

   Do not set this value too high, in order to protect the speaker,

   enabled booster by default

   echo 3 > /sys/kernel/wcd9320/speaker/spkdig_gain
5. Headphone UHQA(Ultra High Quality Audio) mode: UHQA mode allows to have high performance audio, and it's enabled by default. Have better turn off/on music to switch the amplifier for HPH path.

   Enable/Disable

   echo on/off > /sys/kernel/wcd9320/headset/hph_uhqa
