I have a strange problem with my ADAU1462 based custom HW:
The situation is:
I'm well connected to the HW through USBi (SPI), .dspproj is "link compile download" and the connection status is "Active: Downloaded. DSP processing is ongoing and i can listen to the processed audio.
But when i now try to change the parameters of specific filter types (e.q bypass on<->off), the connection fails.
So far, i tested the following and found these to cause the issue:
- Filters->Second Order->Single/Double Precision->Clickless HW slew->All three filter types
- Single/Double Precision->Clickless SW slew->All types tested except ext. triggered types
No issue happens when using the following:
- Filters->Second Order->Single/Double Precision->No slew->All four filter types
Beside of filters, i'm using several other DSP processing blocks like gains (with and without SW slew), mute, polarity, switches, dynamic processors (limiter/compressor), delay. All of these cause no problems.
Does anybody have an idea how to resolve this issue, or how to further debug it?
