LAUNCHXL-CC2640R2: White noise on CC3200AUDBOOST

Part Number: LAUNCHXL-CC2640R2
Other Parts Discussed in Thread: TLV320AIC3254, CC3200AUDBOOST

Dear Sir or Madam,

I'm using the TLV320AIC3254 and I found that there is some small white noise on the audio. This noise become a problem if I modify MICPGA_VOL_CTRL_REG or some other register which are supposed to upgrade the sound of the voice.

Depending on the value I can hear or not the white noise if it's clos to 0x00 I hear nothing but the voice is very low if it's close to its maximum 0x5F I can hear my voice but if I don't speak I hear some white noise even if the microphone is not plugged.

Do you know what could be the problem ?

Have a nice day,

Kind regards,
