Additional testing shows a few things on this issue:

Much of it depends on your power supply to the Pi board.

When you reach the limit of current from the power supply, the connection can get 'noisy'

meaning that the switching transistors in regulation start showing 'pulses' that are never good for a computer with a timing clock.

So a quick check to just the voltage is not always enough. But needs to be done in any case.

Just additional info to look at/for.

I agree on this point. I was running my 28599 node on a usb power supply where I thought for sure it had enough smoke. Nope. The board did odd stuff even shut down a few times. Changed the power supply... not a problem since. Though this may not be your issue, Mike has a good point

Well,

this may not be relevant, but worth saying at this point.

I have found that if you initialize a pi node while not supplying the Pi board with enough current

during the initial start-up. Many things seem to go wrong.

I'm building a bigger 5v power supply to handle 2 or three of these at once to verify what I'm thinking,

but not tested anything yet.

In my case, it is Dahdi

So, just something to look at and if it appears to be likely,

I would say get the required current supplied and start anew with a fresh img.

Not sure if it helps, but something to look for.

Not sure why but the /dev/dsp1 seems to be missing... I've installed oss-compat and tried a number of things.. see below output...

Didi a fresh install of the latest ASL from the repo on a fresh install of raspbian on an RPI 3.  The issue is simple... the pi sees the URI but ASL seems to have issues.. 

I have included sample output from a variety of commands below which clearly details the underlying OS sees the URI as it should, and the given address etc...

see the example output below...
