FS#7402 - Playback fails (data abort) after recording
Starting replay directly after a recording ends in a data abort at 0×40001424.
Stacks: pcmrec is at 68% (IHMO ok), but dircache is 85% but might not
be related.

Not surprising given that the ASM FIQ handler depends on banked registers being left set but it uses a C FIQ handler for recording which fails to save r12. Fix as part of a PCM rework.
This sounds like a duplicate of
FS#7293- although that’s on a Nano.IIUC the data abort is gone now (not counting any nano troubles) but the PCM restart issue still remains. The reason is that the drivers actually turn the audio chip off by running the power down sequence when recording is disabled (which should set things back for playback) so that must be fixed before playback will work after recording.
With two different 5th generation (Video) iPods, after going into the recording screen, playback location doesn’t move and there is no sound. There is no crash. Shutting down and restarting Rockbox makes playback work again.
