my plan is to use a volumio powered board (am not decided yet) as a controller and digital music streamer for a input selector/mastervolume controlling preamp to feed my dsp amps inside of my speakers.
Inputs would be a phono preamp and two aux devices.
I see two options:
First is to use a simple board like a raspberry b+ with dac as just another analogue source into an all analogue signal channel and its GPIO pins for controlling digital potentiometers (master volume) and some relays for changing channels.
Second is to use a more powerfull board and feed it with digitized analogue sources and use volumios software volume control as mastervolume and have spdif outputs, which would be better for connecting my amps.
I have an TA ADC module with up to 24bit/96kHz i2s output already working well with an minidsp ministreamer and my pc. The ministreamers chip seems to be working well as an ALSA device:
alsa-project.org/main/index. … Vendor-ESI
Tenor TE7022L is the chip
Is there a software mixer in voumio where i could enable/disable the ministreamers input and stream it live to spdif output via ministreamer again with software controlled volume?
i hope my question is clear, since i have no board where i can install volumio and test this myself. I need to decide between boards first, either a raspberry b+ or some cubieboard
