depends on the changes, I always build for all targets to be sure... Now with the crosscompilers available it's quite easy to check...
Most important is that it works on the possibly used remotes (h1xx, h3xx,...)

Not shure if this is related to the enhancement pack or not.
There is a problem with automatic file splitting during recording if it should split at max. file size (max. 2GB FAT file size - 1MB). Yesterday I recorded a Jazz concert and this was the first time I didn't set auto time split and I really regret it now because the last quarter hour is missing. :(
The recorded file is actually 2'147'475'500 bytes (3h22m) and this is 2047.992MB and NOT 2047MB as it should be. Really very very close to the FAT limit (only 8148 bytes left).
The bad thing is after this the jukebox didn't continue to record but shut down! There is a following file but the file size is ZERO. And I tried Scandisk and PC-Filerecovery and there is no lost data! >:(
Pre-recording was set to 20s. And I made the observation that if pre-recording is on not all the prerecorded bytes are counted for the file size display. You see this clearly if e.g. at 1min the file size is not 10MB as it should be.
I really have to find out what exactly happened here, I never want this again! And perhaps we should set the limits for max file size less critical, e.g. leaving 10 to 30MB left instead of just 1MB. This would be more save. Aaaah I really hate that I didn't restart the recording during the concert pause! But sometimes bad things happen...
Otherwise I tested my AGC implementation for the 'Live Limiter' preset and this worked fine. Good levels for the recording, some very occasional clips during fortissimo parts but that's no problem. The performance was very dynamic, sometimes more than 40dB from quiet to loud parts.

Did I really say that???
I take it back! :D
Might take a bit longer than I thought!... ::)
Got it all coded but doesn't quite work as it should...hmmmm
I'll keep plugging away at it....

I found the bug. It's not related to the enhancement pack at all. The bug is in 'pcm_recrd.c' in function 'pcmrec_start()':
Line 644 is wrong:
--- Code: --- num_rec_bytes = 0;
--- End code ---
it should be:
--- Code: --- num_rec_bytes = pre_chunks * CHUNK_SIZE;
--- End code ---
to take the prerecorded chunks into account.

That will be my bug then, as I did the prerecording :(
thanks for finding that one!
