In short, the sound card I have is behringer fca610. Then I have an Analog to digital converter. when I connect the ADC to the sound card, even if I do not turn on the audio, there is still noise, crackling. I connect via ODT Toslink.
Audio goes through the chain, but still a lot of noise.
Maybe you need to configure the asio buffer or sample rate. Or where there is so much noise, or you can’t insert the converter into the sound card. And you need to insert into the amplifier or av reviser?
By the way, the sample rate of the ADC is 48,000 hertz. And the output audio is LPCM
