Also the debug information indicates that it is using DirectSound. I actually haven't made a call because of another issue but at least I can confirm that mod_portaudio sees my audio devices in this situation.

> Problem is PortAudio reports there are no input and output devices. I am running Freeswitch on Windows 10 64-bit. The Freeswitch installer is FreeSWITCH-1.6.18-x64-Release.msi which I downloaded recently from files.freeswitch.org. I should explain that I have been using Freeswitch for a number of years and PortAudio used to work, even on this Windows 10 PC. The problem seems to be with the more recent versions of Freeswitch.

I have several input and output devices on this machine, but Dxdiag only lists one output device and it lists no input devices. It tells me I have DirectEx version 12.

Issuing the pa devlist command just lists nothing so it is as if it is just not seeing any devices, but they are certainly there.
