It seems the new bass.dll (even with 1.0.5.30) is indeed guilty. I only play mp3s in Trout, so I don't/wouldn't know if any of the other dlls are flawed ... Is there some way you could contact the bass.dll people to bring this to their collective attention?
I could provide some mp3 files that generate the problem.
I do not think the mp3 files are the problem because no other mp3 player (whether software or a "pocket" mp3 player) "skips" when playing those mp3 files ...
In any case I hope that somehow this problem with Trout will become a thing of the past ... so I can stay fully current with Trout releases ...

Today I updated my (portable) 1.0.4.9 to 1.0.5.29 by only copying in the new Trout.exe - which has "solved" this problem that I have had with Trout in all releases since 1.0.4.9. What could be wrong with any of the other files in the release?

1.0.4.9 never skips on any of my mp3s whether at 32-24 or 128-48 ... but every Trout release after 1.0.4.9 has had an unacceptable playback "skip" problem. By only copying in the new Trout.exe, I seem to have "solved" the problem; but what could be wrong with any of the other files in the release?
