Dear Technical Support Team,
I have some questions about AIC3254.
Q1.)
I'd like to mute DACs if I2S input data is nothing from master.
Could you suggest the way with music_detect on pure path?
My idea is below. I think music_detect's output connects GPIO and host CPU/MCU receives it.
Then host should control volume mute register of AIC3254 through I2C.
The volume component doesn't have mute port , so I didn't connect music_detect's output to volume directly.
If you have more better solution, please let me know.
I worry about unexpected behavior like hung up,
because Master sometimes stops and restarts I2S on some condition of system.
Q2.)
If I2S data from master stops, then BCLK and WCLK stops ,too.
What clocks are used for miniDSP? For example, music_detect needs to operate during I2S stops(BCLK and WCLK stop).
Dose miniDSP operate with MCLK then ?
Best Regards,
