Crackling audio after GCC compiler update?

[hexaae]

C64

It seems that after GCC update 47337dff audio emulation (any driver, I use Wasapi Shared as default) got much worse with audible crackles all the time.

Reinstalled 2.1 public and went back to normal.

(still happens with latest nightly 191b7464 )

EDIT: I was wrong, not a GCC issue. It seems a bug after latest build 191b7464. Previous was still fine.

Fixed with d92d144f (??)

C64 and/or Amiga ?

I'll look into this, haven't done anything with audio lately.

C64 as written in frist msg. Anyway only build f8d5cef8 seemed affected…

P.S.: may I kindly ask you to add a pre-tag like “(C64)” or “(Amiga)” in nightlies description changes?

build f8d5... can't possibly trigger that.

In many cases, the changes apply to both systems. But if it's unambiguous, I try to think about it.

Yeah, that’s what I thought too… but strange enough that build was causing crackles in C64 emu with every game, and just using another build solved the issue. As a double-check I tried again that build and bug re-appeared… However it was an isolated case now solved with recent builds so nothing to worry about IMHO.

I dont’t get a problem with this build. really strange.

warp speed is normal in this build ? maybe the crackles come from reduced speed ? … because of virus scanner … whatever external process.

Not worth taking time away from Denise's development for this transitional rare issue IMHO ;) Will check this out in the future if it ever happens again…

P.S. no the conditions were exactly the same for this build vs others where issue was not reproducible.
