Tungsten T Sound VS Palm OS 5.2 Sound

[exoteric]

I recently purchased the application Delorme Street Atlas 2005 Handheld for my Tungsten T running PalmOS 5.0. After purchasing I noticed that it said sound will not work unless running PalmOS 5.2?! I found this very interesting. So I start looking around on the internet and found several applications that say they require PalmOS 5.2. Among these was Pocket Tunes. I was like WTF?! because I use Pocket Tunes on my Tungsten T running 5.0. Upon closer inspection I see that the requirements are PalmOS 5.2 OR Tungsten T.

So all the got me thinking what is the difference between PalmOS 5.2 sound and Tungsten T sound? Was the PalmOS 5.0 that was installed on the Tungsten T programmed with the Tungsten T in mind so that sound would work and is Delorme on crack saying it won't work when it actually will and that they just need to write a patch?
*or*
Is there some other underlaying factor that I don't know about that makes PalmOS 5.2 the only true OS that their products Voice Prompts will work on?

If anyone has some insight that would be great. I am preparing to send a letter to Delorme to try and get them to do something about it, but I wanted to hear from people that know the OS and the interworks better then I.

Thanks!

I think it's a hardware issue. I own a T2, and before this I had a T1, and both had sound issues with programs that worked properly on OS 5.2 devices. I have this issue on the following programs: Astraware's Hellfire and GTS Racing, and Infinite Dreams's SkyForce.
This page (http://www.astraware.com/help/showQuestion.php?id=72) gives Astraware's answer to the sound issues on T1 and T2.
It's good to see Delorme warns about the compatibility issues with non OS5 devices, Astraware did list T1 and T2 as "compatible" for their games.

Maybe they didn't properly nail down the audio spec in PalmOS 'til 5.2...
