TLV320AIC3204: AGC Target Level runtime modification

kishan patel14

Part Number: TLV320AIC3204

Hi,

Can I change AGC Target Level value runtime for TLV320AIC3204? Specifically Right channel AGC control register D6-D4. The registers are getting modified runtime and I have verified that the changes take place but I don't see its effect in resultant audio when I set 6= -20dB, 4= -14dB, 2 = -10dB. The input audio is 1KHz sine wave tone. Also See the attached snap of audio which is not changing according to Target level changed at runtime.

Thanks,

Kishan

Hi,

You can't change that or volume on the fly even though the registers transaction is successful when AGC is enabled as this is all running in the AGC hardware.

Regards.
