Using Copilot as user manual

[scumballc...@gmail.com]

I was reviewing the Hermes-lite emails and seen there was a frequently asked question about VAC settings not being saved. 

I thought I would put the question into Copilot and got the following response shown below.

I would suggest to users to do a search on Copilot because many times people will not respond to questions which have been asked over and over again.

Why is my VAC setting not being saved in Thetis

If your VAC (Virtual Audio Cable) settings aren't being saved in Thetis, there are a few common culprits to consider:

🛠️ Common Causes and Fixes

• TX Profile Interference
  The most frequent reason settings don’t “stick” is due to TX profiles. These profiles can override many controls and settings, including VAC configurations. If you change a setting but then switch profiles (or restart Thetis with a profile active), it may revert to the profile’s saved values.
• VAC2 Bugs
  Some users have reported issues specifically with VAC2, where settings appear to be saved but audio doesn’t work correctly. This includes persistent underflows in the “TO VAC: (Out)” stream, regardless of the driver used (MME, DirectSound, ASIO). This might not be a saving issue per se, but a functional one that mimics it.
• Driver Conflicts or Misconfiguration
  If you're using Eugene Muzychenko’s VAC app (commonly paired with PowerSDR), it may need reconfiguration for Thetis. Thetis handles VAC differently than PowerSDR, and settings that worked previously might not carry over.
  • Mode-Specific Audio Routing
    Thetis doesn’t automatically switch VAC sources when changing modes (e.g., SSB to FT8). If you change modes and expect VAC settings to follow, they won’t unless manually adjusted. This can give the impression that settings aren’t being saved.

  ✅ What You Can Try

  • Double-check which TX profile is active and whether it’s overriding your VAC settings.
  • Save your settings after making changes, then reselect the same TX profile to confirm persistence.
  • If using VAC2, try switching to VAC1 to test stability.
  • Reconfigure your VAC app to match Thetis’s expectations—especially sample rates and driver types.
  • Consider updating Thetis to the latest version if you haven’t already, as some VAC issues have been patched in newer releases.

  Would you like help walking through your current VAC setup step-by-step? I can guide you through the settings to make sure everything’s aligned.

Hi Reid,

Thanks. This is a very good pointer. I asked AI a few Hermes-Lite 2 related questions and am impressed by what it knows. I have insisted to people who contact me privately that all technical questions go to this Google Group so that others may help or be helped. A public Google Group like this helps train AI too.

73,

Steve
