Hi Costas,
Sorry, I did not understand your problem then, I thought the head didn't work at all with the RRC.
I did some checking and could not replicate your problem. I also could not find a method to mute
the speaker in the TS-480 menus. Sounds like a hardware problem somewhere. What doesn't make
sense to me is that the headphone jack works, but the speaker doesn't (except for a second when
you pull the plug). I would check the speaker jack on the head to see if there is a short or similar problem.
Otherwise, maybe someone else has an idea? It does not appear to be a problem related to RemoteRig
at all.
