Debian upgrade breaks IRLP?

James <james@...>

Hello all -

I've been dealing with a bit of a mystery for the past couple of days.

I run IRLP node 7295 using a 3.0 board mounted in an HP desktop, running Debian 10.  The node feeds an NHRC-7 controller, which is in turn connected to a Kenwood TKR-750.

This setup has been extremely stable.

There have been some changes over the years, with the last hardware change being in 2019 when the old computer I was using started to fail, so I switched to a new HP.

Additional software is only OpenVPN as a secondary control link so I can disable the node from my phone if need be.

I generally stay on top of OS updates.  I performed a full-upgrade on the 12th, after Debian released the last point release for Buster over the weekend.  During the upgrade I was frustrated that tab completion wasn't working in my console so I added bash-completion.  That update upgraded the following packages:

Since the upgrade, my node does not seem as if it sending or receiving IRLP audio from the Internet, although all tests I can do seem to be successful.

scripts/troubleshoot_irlp is successful (except for 2c since I'm not running EchoIRLP).

I have verified my router's port forwarding with nmap from my work, and I can see the open TCP ports, and when connected to the echo reflector I can also see the open UDP ports.  My OpenVPN connection is still working as well, so I don't think there is a problem with the router or internal network.

scripts/audiotest works fine

I emulated that same test with `bin/key; play /usr/bin/soundtest.wav; bin/unkey` and that works.  I didn't really need to do that, I was just at a point where I wanted something to work the way I thought it would.  :)

So I'm confident that the IRLP node is sending audio to the NHRC-7, which is sending audio to the Kenwood, which is transmitting it.

scripts/audio_level_test also works, so I believe that the proper microphone is selected and the volume is correct.  (Which means the Kenwood should be sending audio to the NHRC-7, which is sending it to the node right?)  I get no clipping and an audio level of 69/100.

So everything SHOULD be working as far as I can tell.  I've even done a re-install of the IRLP node from backup so I should have the latest & greatest IRLP files.

But I get no audio from IRLP.  I can connect to the echo reflector and transmit to the node, but watching my router I don't see traffic other than the initial data connection.  And I don't get any hint of a reply back from the echo reflector.

Any ideas?  What am I missing?
