I'm so new to HiFiBerry and the DSP topic, that I'm not even sure I can phrase my problem correctly. But I'll try my best.
I bought a DAC+DSP for the purpose of creating a Raspberry box that takes a toslink input, applies some filters (with Stereo Tools) and plays the modified sound on the toslink output. So, basically doing the DSP functions via software. Now, the problem I face is that whatever I send in through TOSLINK IN, goes out on TOSLINK OUT unchanged. If I understand correctly, this is due to the default programming of the DSP. How can I change this, so that the signal path is TOSLINK IN -> ALSA/JACKD+Stereo Tools -> TOSLINK OUT?
