Default Meters are going & monitoring is on, but there is no sound. Please help?

My setup:

Tascam 16x08 -> Dell 3011t monitors built-in USB hub -> Ubuntu Studio 18.04

This was working yesterday, and as far as I know the only 'interesting' thing that happened was thatsomebody "helpfully" came along behind me and powered off the monitor, which turns off the USB port & effectively yanks the AI out from under the system. I have since rebooted, but still don't get any sound.

So far I've looked at:
  • jack command is /usr/bin/jackd -R -d alsa -d hw:US16x08 -p 128
  • QJackCTL shows 16 system capture devices -> 16 reaper inputs, and 2 reaper outputs -> 2 system outputs.
  • The little things:
    • Track is armed,
    • input monitoring is enabled,
    • the track is *not* muted,
    • volume is turned up on the phones and the track and the guitar
  • The meters flash, so it looks like it's getting the input
  • There are no messages in either QJackctl or /var/log/syslog

What am I missing?

Thanks in advance for any help.

Check the volume controls of the alsa driver. You can check them with alsamixer. Maybe the speaker control of your soundcard is off or muted or just down to zero.
