I would need way more details before I could make a recommendation.
AV Receivers are designed to process surround sound and then feed them into a SINGLE ROOM for surround sound audio or to power speakers as appropriate. A multi-channel amplifier with multiple rooms that need audio can typically get that audio from the analog connections from most of those devices.
If you are NOT doing surround sound anywhere, then you can get by alright with a pretty basic solution. If you are doing surround sound in one area, then need stereo for other locations, then you will need analog audio outputs from your sources at the very least. Surround sound and stereo aren't carried over HDMI at the same time. Pick one, or the other, which makes surround and stereo rooms completely useless (THANKS HDMI!!!).
How do you intend to control volume in all of these spaces with speakers in them?
A concern people will have, myself included, is that you have a Pyle amp. You may have a very decent setup, but Pyle is not well known for putting out quality product. So, you may have started walking down a path which isn't great overall. But, that doesn't mean that you won't get help, it just means that you may not get the exact results you were expecting.
Typically a room will have no less than two speakers in it. This is because stereo is the industry standard. Two speakers, or multiples of two speakers, setup in a 'best possible' stereo configuration. You can convert from stereo to mono using adapters easily enough, but this isn't typical and is rarely much less expensive.
Since every room may want to listen at a different volume level, and you may even want to play something different between rooms, it isn't uncommon to use whole house audio distribution units. But, those will be entirely analog units as well.
HDMI is simply not designed for whole-house audio distribution, and you will lose surround sound if you wanted it, the second you start integrating HDMI devices into a distributed audio system (with a few exceptions). You will not get better audio by using HDMI when your rooms are stereo.
You can use a device like the Marantz 6013 listed above and that can get you 'all channel stereo' to everything. Then you are using a single source to all rooms with a stereo feed and up to 7 speakers being processed. But, it isn't expandable, and volume from the Marantz will impact all rooms at the same time.
A more typical audio distribution system would be something like this:
DetailsThe MC-66 is the most affordable whole-house audio controller available that includes these features and this high level of build-quality. Add a KC6 or KC7 keypad into each zone and/or use our MC App to send and receive signals to and from the controller.Use the pre-amp outputs in each...

For any sources that you need to convert from HDMI to stereo, you can use a $30 HDMI audio extractor on.
