Impossible Mission buggy audio

  JohnnyG

   Does the speech synthesis on Impossible Mission work for anyone?

   "Stay a while... Stay foreverrrrrrr"
   I was so looking forward to hearing that again after all these years - but
   it doesn't play.

   And then sometimes when you enter a room he is meant to say "destroy him
   my robots" but I just get silence.

   Ideas?

   [2]JohnnyG I played Impossible Mission (badly!) at the weekend and the
   audio was fine. I'd agree with [3]Gurce that it may well be the current of
   your power supply.

   I've heard it say the "another visitor" audio when it runs on my system,
   not sure why it didn't work for you. Some people have mentioned seeing
   issues with the video if they use a usb adapter rated 1A or less. and then
   the prob goes away if they use 2A or higher. Not sure if this will help
   for your audio troubles though, but maybe worth a shot.

   Do any other games with digitised audio work for you?

   I look forward to hearing “No, No, No!”

   Followed by the female voice saying “Mission Accomplished,
   Congratulations!”

   I only finished it once all those years ago but the final words stuck with
   me all this time.

   I forget what I had for lunch a few days ago but this I've never forgotten
   in 33 years - some things are just more important!

   I am using a 2A iPad charger and so lack of power should not be causing
   the issue.

   I just tried it on a different TV and it worked?? wth
   No idea why hdmi audio would work differently...?

   [5]JohnnyG Wow, that is puzzling. Any chance you could share the
   make/model details of both working and non-working tv's?

   There is no single, universal HDMI transport layer as such. HDMI supports
   a broad spectrum of signal frequencies and features. While the basic
   principles are pretty much the same across devices, devices running at
   slightly different frequencies or with slightly different tolerances may
   not work together, while some are more forgiving than others. Unlike CRTs
   where everything is purely signal based so you still get a fuzzy picture
   if things are not right, HDMI is digital so, usually, it's working
   correctly or there's nothing. Different OSes push slightly different
   signals out their HDMI ports, too. In particular, I have found that MacOS
   and Windows (along with DVD/BluRay players and hardware based consoles)
   are able to correctly synchronise with more types of screen and over
   longer cable lengths than Linux.

   Since the Mini is Linux, I would expect more variation with device
   compatibility than something that wasn't, to be honest. [7]😞

   On the original C64 the speech was dodgy through the aerial, you had to
   have it just right. Via the scart lead on the original C64C and the mini I
   have found the speech to be low. I think it’s an issue with the original
   game and not the mini.

   Hi, I have the same issue, but I think it's relates to general audio
   issues because there are problems also with other game music as monty on
   the run ( listen to the intro) before the lead melody and others
