HifiberryDAC+ and usb-mixer for analog audio in

Hi, I have got already a Hifiberry DAC+. Is it possible to use a second usb-mixer in Zynthian?
Alsamixer shows both devices to me. But how can i configure Zynthian to use the usb-mixer for analog input? I mean Audio out should use then DAC+ and Audio In should use then external usb-mixer.
Thanks a lot!

It’s not straightforward. Jack can usually only use one audio device due to its precise timing requirements. There are a number of ways to go about it but I would configure jack to use the Hifiberry, then use pulseaudio with the jack sink to manage audio from the mixer into jack.

Note: there are further issues regarding usb audio devices with the rpi documented on this forum.
