Coincidence? Serendipity?

I just tried the latest builds from: http://dvswitch.org/files/ASL_Images/Raspberry_Pi/Stretch/

Liking asl-menu... that helps... but as with others below... I have found, on a Pi3 + RA-40 that works under the prior 'build' - I too am experiencing multiple errors and ultimately failure of asterisk app to identify, connect to and use the USB-connected RA-40 as either USBRadio or SimpleUSB that worked under same configuration parameters. It's even complaining that asterisk.ctl is not in /var/run when it clearly is there.

On the console I am getting low voltage errors I never saw before... using the same power source. Measurement at the board is minimum 4.96v. Power source is a PowerPole USBBuddy 3A device from clean DC - these run all of my field-racked nodes so far. Even a 1.5a wall-wart has been fine prior. Doesn't make sense when the operational voltage tolerance of the Pi is greater than this 0.8% difference. If the low-voltage check is getting in the way... how do we fix that? Separate power sources for Pi vs interface boards?

If the voltage issue is NOT "getting in the way" of Asterisk using a good known USB-interfaced device? What is?

Again, I can shut down the boards, swap the USB Flash drive from the latest build to the prior and it runs fine. I'm reluctant to in-place update the working node/stick... until I can properly clone the stick and test on an expendable build. (What tool does one use to make an image from a bootable stick?)

Yeah it's decidedly an issue with snd-pcm-oss missing from the system..
