Recording via optical-in
dgodwin:
DAT was originally recorded at 44.1k Played on a Fostex D5. Rockbox directions were followed after installing the build:
reset cfg
optical output = on
recording source = digital
frequency = 44.1
Started the DAT
went to recording screen, and hit record. Levels were bouncing, and everything appears fine. I had to stop the DAT, and do a switch (the encore of the show was on another DAT) so I left the iRiver recording, to see what would happen. It kept recording, and when I got the DAT going again, it didn't show any problems.
I transfered the recorded audio onto my computer, and opened it in adobe audition, and it played fine, and looks normal.

Switched to the 4-24-2006 - 1600 build.
I am still getting issues having my H120 flushing the buffer to the HD. The HD red light is on and the peak signal dies when this happens, then it locks up. I tried this tim feeding a signal from my CD player.
manno:
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.

This pretty much describes my experience, but I've only tried 44.1k, so I can't confirm the downsampling. I'm betting most would prefer no resampling regardless of bit rate (at least 48k or less)
manno:
Another test..... recorded about 53min of 24/48 stream. It still captured at 16/44.1 but after transferring the file and upsampling it to 48khz, the file was perfect (or at least no errors that I can see or hear). One cool thing though, even though it was downsampling to the HD, I was using headphones to monitor the stream and it was perfect!
