I have a problem whereby Mac A cannot ping the local network. It can ping the router, 192.168.1.1 but none of the machines on that network. Mac B works properly.
- I am running yosemite 10.10 on both macs.
- I've tried deleting the network settings and starting again (on Mac A)
This is also preventing (which) mac from discovering my SONOS network (which is or isn't different than the local network??).

Ping can be suppressed by a firewall, so I like to take a more overall view.
If you have hidden the "shared" sidebar in finder, you might have to un-hide it. Alternatively, you could make a new test user account on both Macs and use it for troubleshooting. The default Finder settings will show shared Macs on the local network.
At that point, you'll know a bit more about the network and possibly want to power off both Macs and power off the router and then start them all up again.
