I used to have a Bose dock in the bedroom which we used at night to play rainfall/thunderstorm sound while we were sleeping. (On iPhone with Sleep Machine app for anyone interested.) That setup started to get a bit sketchy with Lightning -> 30 pin adapter cable between the new phone and the old dock not always charging my phone, which coincided with my starting to collect Sonos gear.
I added a Play:5 and an Airport Express using the "official" method of getting AirPlay support on Sonos. Mostly worked, but without fail, the AirPlay connection would cut out, sometimes even disconnecting outright, which was not ideal.
Figured I'd take AirPlay out of the equation - given that there are a couple dozen or more wifi networks that overlap my house, sketchy performance from time to time isn't unexpected. Got a one month subscription to Calm Radio and figured Atmospheres would probably work.
Unfortunately, the Play:5 bass response means a lot of the rain comes with thunder loud enough to startle my wife out of bed. Other channels have birds or other components, or just varying volume levels that I seem to be particularly alert to when I'm sleeping.
The simplest (and surprisingly, cheapest) path forward would seem to be MyNoise.net streaming, but he seems to stream in OGG which is unsupported by Sonos.
Any great ideas on where I could find a consistent, level, rain sound generator, or possibly just basic white noise, without other included sounds, that plays via Sonos? Not opposed to a subscription - I had high hopes for Calm - I just need something that works for this situation.
