Welcome to the Rockbox Technical Forums!
Ok, so I was able to test it out.... So far it seemed to work OK. I did a couple of short test files, one about 70mb in length and one about 40mb in length. They both came out ok EXCEPT that I fed it a 24-bit/48khz signal and it downsampled it to 44.1khz and trucated it to 16-bit. But it did flush the buffer to the HD ok. What's the possibility of keeping the sample rates (not to exceed 48khz) and doing at least 20-bit at the hardware max?It's looking good here!BTW, on my end when it flushes, the HD led stays on and it appears to lock but after a few seconds, it then picks up again.

However, it always downsamples to 44.1kHz when playing back the file.
I checked all my setting and made sure that it was being sent a 48khz signal and it is but still downsampling to 44.1khz no matter what I do. Isn't it hardcoded into the patch to only do 44.1 at this time?
Is not the resulting wav in fact 48 kHz PCM data with just a 44.1 header? Is not the recored wav time length about 9% bigger and does not the sound have a lower pitch?
