I then look at > parec0.raw by importing it in audacity (u-law, 6channels, 8000 smp/sec). I tested it here. To me it looks like a bug that occurs because of re-winding and using a monitor source, but I can't put my finger on it yet. With your setup, you are running with 2 seconds latency, which is probably not what you intend. Add --latency-msec=10 or similar to your parec command. This should mostly hide the bug.
