FS#13166 - iRiver H300 ALAC codec crashing (CPU frequency switching)

Please refer to forum post for full exchange: http://forums.rockbox.org/index.php/topic,52518.0.html

In summary playing ALAC will crash the unit, other codecs not as much. My reasoning is (as contained in the forum post):

Converting some of my ALAC collection to FLAC to test has given excellent results = no crashes. I am suspicious of the ALAC decoder; watching the VIEW BUFFERING THREAD there seems to be consistency:

OGG/MP3/FLAC/WAV: CPU Frequency goes up to 124 until pcm: becomes full, then drops to 45mhz and pcm: hovers (it is always active) near the top of 100%. Upon track change the cycle starts again (124mhz until pcm: becomes full). I don't seem to get crashes.

ALAC: CPU Frequency goes up to 124 until pcm: becomes full, then drops to 45mhz and pcm: quickly goes down (takes about 2 seconds) to 75%, then cpu switches to 124mhz to get pcm: back up to 100%. This goes on constantly (cpu high - low cycle) while a single track/file is playing. I am now believing this cpu going up and down constantly gives me the crashes. Note on crashes: I don't know when they will happen, sometimes after a minute or two, sometime after 10 minutes , there is no pattern I can tell.
