Still struggling with this problem, but ran some more tests:
- I thought it might be a disk access or latency issue; So
I invoked arecord with "nice -n -20" and directed the recording
file to be created on RamDisk - same result - after 30 seconds
the recorded audio file switches to a loud hissing
My VXPocket V2 records perfectly each time at -f S24_3LE
-c2 -r 48000 for the first 30 seconds. After 30 seconds have
passed, however, it records only a loud, hissing noise with
no evidence of the original sound source.
The length of time until noise (30 seconds) seems very
accurate and repeatabl
