I have a base zero W that I want to turn into a receiver for spotify connect and some old speakers that connect via a 3.5mm jack.
I want to get audio out of it that isn't horrific sounding (such as $5 USB to 3.5mm DAC) but doesn't have to be stellar. I have an existing HDMI splitter that outputs a hdmi signal to hdmi/spdif/and analog stereo. Since I have this already and the sound is fine, I thought it was worth starting here.
Firstly I need confirmation that if I run a micro-HDMI cable to this splitter, that I will be able to split analog audio from it? I guess the question is whether there's any hurdles in getting audio as expected from the micro-HDMI port of a zeroW or will I need to do anything further? In my research I saw a possibility i may need to edit a config file.
Secondly The HDMI splitter is powered over DC via a micro USB jack. I doubt that the USB power from the zero W output is enough to power this but thought I would check. This should be a simple comparison of specs but I can never quite confidently understand this stuff.
The HDMI splitter says its max working current is 190mA and standby power is 5V/500mA. From my research, is it as simple as saying 190mA and 500mA are both higher than 100mA (the most power that should be drawn) so it's a straightforward no unless I want to rewire stuff (which I don't)?
I'm unsure if 100mA applies to the zero W. On the other hand, this post suggests the output is only limited by the input into the zero W but to be careful. I'm using the official UK power adapter for the zero W (5.1v/2.5a).
I suppose an unusual caveat here that goes against the grain is that I'm not particularly technically-minded or interested in tinkering or DIY. The idea of having two power plugs for this project (the pi doesn't have any usb power source nearby) is off-putting enough to reconsider it. As is soldering, custom cases, or going beyond editing config files. I'm inept at these and always seem to break things. I also need a neat, small solution and an oversized box or exposed wires is going to get complaints in the house from others (so adding a hat or board that breaks it out of the tiny standard case is not a simple solution for me).
Obviously I'm the sort of person who should be looking for a small chromecast etc. It just feels a shame to waste the zero W while I'm looking at adding another spotify connect point. I completely understand the lack of empathy coming from a raspberry pi forum for someone like me!
