Hello,
We are using TLV320AIC3204 audio codec with our device. When we are configuring the register mentioned below, it will start the noise in the speaker/headphone.
i2cset -f -y 3 0x18 0x00 0x00
i2cset -f -y 3 0x18 0x01 0x01
i2cset -f -y 3 0x18 0x0B 0x81
i2cset -f -y 3 0x18 0x0C 0x84
i2cset -f -y 3 0x18 0x0D 0x00
i2cset -f -y 3 0x18 0x0E 0x40
i2cset -f -y 3 0x18 0x3C 0x08
i2cset -f -y 3 0x18 0x00 0x01
i2cset -f -y 3 0x18 0x01 0x00
i2cset -f -y 3 0x18 0x02 0x00
i2cset -f -y 3 0x18 0x7B 0x01
i2cset -f -y 3 0x18 0x14 0x25

i2cset -f -y 3 0x18 0x0C 0x08
i2cset -f -y 3 0x18 0x0D 0x08
i2cset -f -y 3 0x18 0x10 0x00
i2cset -f -y 3 0x18 0x11 0x00
i2cset -f -y 3 0x18 0x09 0x30
i2cset -f -y 3 0x18 0x00 0x00
i2cset -f -y 3 0x18 0x3F 0xD4
i2cset -f -y 3 0x18 0x40 0x00
i2cset -f -y 3 0x18 0x00 0x01
i2cset -f -y 3 0x18 0x03 0xC0
i2cset -f -y 3 0x18 0x04 0xC0
In that sequence, when we are setting the highlighted register, it will give the noise. I am attaching the schematics for the audio codec part.
Please help us to stop the unwanted noise. Please do let me know, if anything else require.
Thanks and regards
