Hey just a note to the thread:
I tried using an old class 4 MicroSD card at 2448, but it crashed thrice in a few hours.
I kept restarting when I noticed, but didn't think to switch to internal storage at the time.
The PCM-A10 seemed to be monitoring fine via bluetooth and the RecRemote app whenever I looked, but the end of each file before the crashes has several minutes of digital junk that I can't seem to turn into music.
I tried to import the junk as raw 1 channel, or lower bit rate, but no, it seems to be just crud.
I blame the old random card I found in my stuff and figured would work.
I doubt the card is bad, just old and slow.
it's labeled like this:
Kingston
MicroSD HC
8GB
C08G Taiwan
Kingston®
SDC4/8GB 18
should be 4MB/s which should be adequate for 24/48, but I guess not.
Recommend to test new cards in advance, and not cut it close on specs.
