It seems nobody knows what could be the problem here. Maybe it will help 
if I post more of the debug output - here is an extract from the broken 
version:

main debug: thread 1972 (waveOut Notification Thread) created at 
priority 15 (waveout.c:340)
main debug: using audio output module "waveout"
main debug: output 'spdi' 48000 Hz 3F2R/LFE frame=1536 samples/6144 bytes
main debug: mixer 'a52 ' 48000 Hz 3F2R/LFE frame=1536 samples/6144 bytes
main debug: filter(s) 'a52 '->'spdi' 48000 Hz->48000 Hz 3F2R/LFE->3F2R/LFE
main debug: looking for audio filter module: 23 candidates
main debug: using audio filter module "a52tospdif"
main debug: found a filter for the whole conversion
main debug: looking for audio mixer module: 3 candidates
main debug: using audio mixer module "spdif_mixer"
main debug: input 'a52 ' 48000 Hz 3F2R/LFE frame=1 samples/1792 bytes

So it seems that somewhere along the line it has forgotten that 
frame=1536 and has instead set it to frame=1. However, I don't know 
which source files I should be looking at to try and locate the change 
that caused the problem. Can anybody point me in the right direction?

Thanks,
Ben
