VICE: Sound buffer overflow

[MIRKOSOFT]

Hi!


I'm using non-install VICE 2.2 x64.
All was working correctly.
I customized my C128 machine, add JiffyDOS etc.
Long time I was using without JiffyDOS - no problem.
But now (not every running) VICE displays to me message in attachment (Sound buffer overflow) and sound output is terminated...


Can anybody help me what to set to prevent this error?


Thanks.
Miro
