An alternative would consist in low-cost I2S devices, like the Adafruit I2S Stereo Decoder - UDA1334A. I don't know anything about the sound quality, but it's a stereo DAC below 10€. I'm not sure how many I2S devices you can plug at a raspberry. But since there are ALSA driver available, this would would provide a starting point to possibly connect several of those devices. This could be a low budget route. Presumably there are I2S DACs with more channels. In addition, last December there was a thread on "recommendations for output-only audio devices", where a < https://www.minidsp.com/products/usb-audio-interface/u-dac8 > was mentioned.
