You right, probably we should add better reaction on broken files :)

Not sure how do that on windows, on linux that can be done by command 'flac -t *.flac'.

thanks. if it currently ignores small broken chunks - maybe we could increase the tolerance... or at least do something to avoid the noise before skipping. makes me jump every time. I'll go fix up the files though. 1mb chunks missing out of 30mb tracks is no good :)

hmmm I'm not sure it's adding up.
There are 3500 FLAC files on the SDCard.
10 were corrupted . I've re-copied them from the NAS or re-ripped them re-tested test decoding with dbpoweramp . (that picks up corrupted frames of invalid checksums)
(no more Error: Watchdog timeout, possible CoreConverter crash
Encountered 'FLAC__STREAM_DECODER_SEARCH_FOR_FRAME_SYNC'
md5 did not match decoded data, file is corrupt.
)
Here's the thing.

there are many similar still open flyspray issues.
I'll keep an eye if it happens again but the general feeling from me is - while part of the issue was the definitely corrupted files, it happens far too frequently for it to just be related to those. (as in it skips far too often for it to add up to 10/3500 on shuffle).
thoughts? anything i can do to narrow it down. Reading the previous tickets (ones not relating to specific files or broken card) it seems like people are saying they can't repro it at times.

Latest build have some fixes for SD and internal drive. If you still have reproducible problem - report about it.
