Dear TI support,
I have a small 2.1 channel Home Theater (HTIB), that uses two TAS5611 chips. One for the front channels and the other for the sub. They work in master/slave mode that is the front amp is the master and the sub is the slave.
The problem is the whistle (teapot like) sound that is occasionally heard from the sub when playing music. The whistling stops after few sec when the music stops. It sounds like an AM interference, but not sure.
The front chip uses a 10K resistor on the FREQ_ADJ leg, but there is no whistling on the main channels. How can I avoid the whistling on the sub in this configuration ? Change the resistors to 20K for lower freq would help ?
Thanks,
Zoltan
