Ooops, looks like we missed this in the current DSP profile. We'll come back with a new one soon...
Can you try this one:

Unfortunately I didn't find the time for full testing, only tested that the input pass-trough is working at all. So no guarantee this works perfectly. If there are still problems, let me know and we'll look into this again next week. I just didn't want to let you wait over the weekend.
Cool! Now it works using arecord (arecord -d60 -fS16_LE -r44100 -c 2 s16_44.wav)
What it doesn’t work is with HifiberryOSalpha8 and alsaloop. It starts playing music but after 4 o 5 seconds stops. This is the journal log:

I’m not sure if it is useful, but is all I get.
Thanks!
Digging a little bit more, it seems to be something related to the Web interface of HifiberryOS because both:
/opt/alsaloop/alsaloop.py 0
And
alsaloop -r 48000 -C hw:0 -P hw:0 -l 256 -s 0 -U
Works fine.
Thanks!
Hmm, looks like a general bug in the loop application. Do you see the same problem without the DSP add-on?
Yes, same problem without the DSP add-on. “Start when signal detected” doesn’t work, and when I enable analog input manually, most times audiocontrol2.service restarts (seeing journal log) and in some occasions it starts playing input sound but only for few seconds.
However, executing alsaloop.py through ssh works perfectly after disabling the service (systemctl disable alsaloop)
