Here's an RMAA test, default Rockbox compared to FS#12111+11304: http://rmaa.elektrokrishna.com/Temp/...11%2B11304.htm
There are some very tiny differences between the builds, as keyb_gr already mentioned above. The build with FS#12111+11304 included seems to be a tiny bit louder than the default build (less than 1dB). So I did a second set of measurements, where I increased the input volume on my sound card by ~1dB for the stock build, to be more or less equally loud as the patched build (or even a little louder): http://rmaa.elektrokrishna.com/Temp/...Matched%29.htm
- THD and IMD results are still the same, ie. a little better with the patched build.
