do you have a small/minimal PTP example (.kpt file) that shows the problem?

I'm short before releasing the next krpano version and have already removed several outdated and unnecessary device checks and workarounds (like a autoplay workaround) from the PTP xml templates that might be related to sound problem, but I'm not able to build a non-working PTP example so that I could test if these changes would work.

Best regards,

in the mean time i got it to work with a file provided from panotour plugins guy -…-krpano-1-20-x/

thank you for everything klaus, since many many years you are doing incredible work for us 360 freaks ;), keep up the good work!

I have checked that file now - it basically does the same as my template updates in the 1.20.7 release - it removes the sound-autoplay-workarounds from PTP.

The newer krpano versions are handling all kind of autoplay-restritcions and workarounds automatically and these old manual workarounds in PTP are not checking if an workaround is even necessary and are therefore conflicting.

Best regards,
