FS#9213 - Fix for audio dropout after startup
Since a few weeks, I’ve been noticing short audio dropouts a few seconds after starting Rockbox on an iAudio X5. I haven’t changed any settings recently (at least I can’t remember anything 
and I haven’t done any Rockbox software upgrades. My guess is that’s it’s caused by my disk becoming more and more filled.
Using the debug log, I noticed that the dropouts happen after the “reverse scan…” message. The “audio thread” debug menu showed me that the dropouts are caused by PCM buffer underruns. So I added a yield()-call to the check_deleted_files() function and the dropouts were gone.
The patch below is against the latest SVN version. I tested it with an older Rockbox version, but the code looks sufficiently similar that I don’t see why this shouldn’t also work with the latest trunk. Could somebody please apply it?

Sync'ed against daily build of 2009-02-24 (r20096), just a line offset.
It seems that it fixes the drop out: me too I have a quite full HD (ipod video 80 GB, about 65 GB used).
But I want to test it more.
But the problem still happens more times when the DAP is rebuilding the dircache.
I think that in this case the problem has a different nature.
I used RB normally, taking care that it doesn't rebuild the dircache: unfortunately, the problem is still present.
The HD is quite full, I will try to perform a "defrag" like operation, then I will inform you about the result
Finally I "defrag'ed" the DAP: I just copied all the HD content to an external HD, emptied the DAP's HD, then re-copied all. I don't know a defrag tool for a GNU system, except for "pyfragtools", but I never tested it.
The dropouts are disappeared!
Just for curiosity, I would like to test with a daily build, without this patch.
Thank you very much.
I never got the drop-out also without this patch.
