Hi Team,
There is a setting problem on the TAS5822 demoboard, Tweeter mode has output, but Woofer mode has no output
In Mono 1.1 mode,
Input 200Hz from SPDIF into NO Cross Over
LRCK=48Khz Tweeter & Woofer have output
LRCK=96Khz Tweeter & Woofer no output
Hi Jack
It means the DSP will use 48KHz to do the calculation for this process flow. It doesn't affect you to input 96KHz, because there's SCR block in every process flow, it will transform input sample rate, downsampling 96KHz into 48KHz.
Hi Shadow,
Here is register status for 0x70 and 0x68.

Hi Ken
It seems they are changing the sample rate during PLAY. Do we have the real using requirement in the products?
Please follow the guidance in the datasheet if we need to do this. The clock Halt is a must have.
Hi Shadow,
Okay, I can get the 96Khz output at OUT1A(Tweeter) and nothing output at OUT1B(Woofer) as below setting.
There is only Left channel at I2S data output.
If change the Output Crossbar to as below setting, then, I can get nothing output at OUT1A, and get 96Khz output at OUT1B.
There is only Right channel at I2S data output.
You can duplicate this issue by yourself with TAS5822MEVM and select Mono 1.1 mode via optical in with 96KHz sample rate and playing 1KHz sine tone.
Best regards
Ken
