whether the ST play YM sound at that time or it's an STE playing DMA 
sample, I don't think the result will sound better than inserting '0' 
bytes. You will have an audible change in the audio output.

If we have a 20 KB buffer and we duplicate 10 KB of data, I don't think 
it will give a nice result. In fact, I don't see the logic of 
duplicating existing data to create missing data. I'm not sure that 
playing non-null data is better and less audible than inserting null 
bytes (especially in the case where the ST plays a digi sound, maybe 
it's less audible for a "simpler" ym music)

In both cases it depends on how many samples are missing. But if half 
the buffer is regularly missing, then there's not much we can do, the 
user just have a too slow machine.

Maybe a wav recording can be made from Hatari, then write a small c 
program that ramdomly duplicates 1000 bytes several times at different 
positions in this wav, and set these bytes to null in another wav file.
