It appears you are not using ken's panel but are using the one by Dany Setyadi - airbus_a340_panel_v1.1.zipThe simplest test you can make would be to comment out gauge 29 like this://gauge29=ID_AltHorn, 85,390,21,18(add the two foward slash marks)That should stop the sound you find so annoying.Let us know if this "fixes" the problem.PS - I just tried it and it worked for me.

well whosever it is, I finally killed it. Gauge 29 was the culprit. I just did a "//" in front of it, renumbered those following and no more horn!

it probably is. I guess the A340 panels looks very much alike and that is the gauge that caused my problem. Until today! :)

I did and it's fixed! Sorry about the mixup in the panel authors.

That is good news.FYI - It was not necessary to re-number your gauges after commenting 29 out - That was good form, but not necessary.
