Hi,
I have a respeaker (2 mic array) for my rhasspy and I would like to combine the same hardware for snapcast to play music.
My requierment is to have it power efficent as I dont want to pay electricity for something that will not be used 24/7.
So I have been looking at speakers that I can power over usb & use the 3.5mm plug but the quaility have been horrible, it could work for rhasspy but no way for any type of music.
So I was looking at a AMP hat to power the speaker from the rpi with some hope (nothing confirmed) that it would use less power or if I would be able to turn it off when not used. The idea was to combine the respeaker hat & amp but looks like the pins are over lapping besides the i2c when I check https://pinout.xyz/pinout
As an alternative to skip the extra hat I would also be OK if there would be any good quality speakers that would turn on automatically (without me needing to have a extra AMP hat) when there is sound over 3.5mm so I can reuse the respeaker, I am a bit sceptic to solve this my self by adding relays to the rpi.I got a tip on system audio’s SA saxo series that would automatically turn off after 20 min but I am not sure if it will automatically turn on. The best answer on a speaker I found so far is is from audioengine (Support Inquiry — Audioengine).
Is there anybody that built a power efficent setup with good audio quality or have any idea on how I should go forward?
