Hi slimhase, I too had problems of noise from the pi analogue outputs ( builtin, self-built on zero, and external dac's) when connected to a small amp using the same power source as the pi. You can either use a separate power source ( 2nd set of batteries ) or avoid it by using a dac+amp board. I just got my phat beat going with PCP and I am pleased with the d-amp feeding the speakers. Enough power for small applications, and no noise from powercircuits or wifi. I use them with my hifi speakers ATM and the music is flawless, except the plops at startup of squeezelight are not suppressed. There are also other dac+damp solutions available; the speaker bonnet, a MAX98357A board, boards based on the wolfson chipset . As a solution for WIFI on the go; I emulate my home wifi SSID with my smartphone its hotspot. The the pi ( pcp ) connects without knowing it is on the road. Fixed reservations in the DHCP is an problem though, my phone hotspot does not cater for that, however the same solution from my laptop does. I have not really used a LMS implementation on the zero, but a 64 Gig SD is affordable these days, and can provide some local storage. I should try that on my next holiday.
