Re: [hatari-devel] sound bug

Ok if those patches relate to known issues in sample replay, it would definitely be worth testing them. Or even if they relate to known issues in sample recording which likely apply to sample replay it would still be worth testing that.

Unfortunately I can only test replay, not recording.
