Part Number: TLV320AIC3105
I get the issue with tlv320aic3105 when I test playback and recording. I turn on the audio board, configure the tlv320aic3105, I test playback and recording, and they look good; but after I test playback and recording, tlv320aic3105 stops working, I must reset the tlv320aic3105 to get playback and record to work again. I don’t know why tlv320aic3105 stops working.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Below are the captured register values:
Page 0/Register 3: 0x20 (P=8, Q=4, PLL is disabled)
Page 0/Register 4: 0x04 (J=1)
Page 0/Register 5: 0x0
Page 0/Register 6: 0x0 (D=0)
Page 0/Register 11: 0xC1 (ADC overflow)
I checked that the system clock is 24576000, FS ref (sample rate) is 48000.
It looks that ADCs are overflow. I was doing software reset (write 0x80 to page 0/register 1) and it doesn’t work, I must shut down the system (host processor am335x and tlv320aic3105) and restart to get them to work again.
When the codec playback and record work, record has loud background noise.

TLV320AIC3105 is working fine right now, I re-configured the chip to fix ADC overflow issue.
