Hi Anna,

Hmm, sounds like CPU use. Nothing that a low battery would affect (I don't
think).

Nothing that was changed today should have affected this, although
previously the AAC codec and voice file may have been "sharing" the same
memory (i.e. potentially corrupting the voice file), maybe that had a
positive side-effect somehow...?

Note that older versions of Rockbox (before August 1st) didn't allow playing
back .talk clips during audio playback, so since then the chance of 2 codecs
(AAC for audio, MP3 for .talk clips and voice) being used together has
increased somewhat, which will undoubtedly use more CPU. Perhaps there
needs to be an option to disable this behaviour, or the voice codec needs to
give up if there's not enough CPU.

Or maybe something is up with the IRAM handling? I'm not familiar with the
IPod at all, but I'll ask around and see if I can work it out.

Ever since you sent me your example AAC file, I have always found that it
plays back skippily on my IRiver H340 (with voice enabled). I assumed this
was "normal" as the AAC codec is not optimised yet... being an MP3/OGG user
(both of which are fine).

Please can you try yesterday's daily build -
http://download.rockbox.org/daily/ipodnano/rockbox-ipodnano-20060823.zip but
leave everything else the same (e.g. voice file, settings) and see if that
improves matters or not?

Yours,
Steve Bavin
