Details

If a voice file is in use, the CPU is always boosted during playback.

When in the "unwanted boost" state, the CPU boost log shows the following:
B main.c:328
B common/dircache.c:554
U common/dircache.c:563
B tagcache.c:3835
U tagcache.c:3853
U main.c:542
B tagcache.c:3803
B thread.c:915
B playlist.c:1219
B talk.c:218
U talk.c:230
U tagcache.c:3816
U playlist.c:1244

If I read this correctly, it indicates that the unwanted boost was started in thread.c:915. This just indicates a call to trigger_cpu_boost() was used, very likely one of the calls in playback.c...
This task depends upon

This sounds an awful lot like the bug I fixed in february. It must have resurfaced due to some other changes.

Could it be the new "timeout loop" added to voice_request_buffer_callback() in here:

The FIXME on line 929 looks suspicious. :-)

/me shall henceforth refrain from adding suspicious comments :P

This seems to help... not sure if it results in the boost clearing too quickly, but it doesn't make my H340 slow down noticably.

Maybe MikeS could look at it, and an iPod Video user could test it?
