That's true, TC2048 has no AY on-board (they are available, in standard of Spectrum128, but only as external AY interfaces).
Anyway, here is the TAP file:
http://mister_beep.republika.pl/COSMIC_Escape.TAP
(sadly without the intro, but all the rest still exist in the TAP).
I still don't know if and how it works on TS2068 though. :(
Anyway, computer plays 3 independent digital audio channels but mixed from one (software mixing) and the quality is 1-bit.
If anybody could convert OUT commands from ZX128 standard to TS2068 standard - then the song could play from TS's AY chip with quality of 4bit. Then it wouldn't be software mixing btw, but real 3 channels.
There is an old music-editor to make these songs and if anybody's interested in cracking it and changing into TS2068 AY standard - I can give you a link to the program.
Greetings. :)

Hi again. Here's some info provided by Mike, author of EightyOne:
128k spectrum 1.7734 MHz
Timex 1.764 MHz
ZON-X 1.625 MHz
Fuller 1.625 MHz
QuickSilva 0.8125MHz
As you can see, the Spectrum and Timex are quite close, whereas the ZX81 boards use a slightly slower clock - probably as a result of the spectrum using a 7MHz crystal and the ZX81 6.5MHz.
The list shows the clock frequency used by the AY chip on each computer and interface. As for which ports to use, I would probably check the TS2068 manual. Maybe someone here in the group remembers, or you could PM the user 'Alcoholic Anonymous' and ask him. I think he's one of the people who hacked (or knows how to hack) games to make AY stuff (that was meant for the 128K Spectrum) work on TS2068s.
