Sorry for the delay, I was on holidays last week. OK, so if it isn't pulseaudio, we have to dig further. Can you please generate a full strace:
sudo killall hald Now make sure that sound recording works and capture the trace: strace -f -o /tmp/arecord-works.strace -s 1024 -v / /usr/bin/arecord -D hw:1,0 -d 3 -f cd -t wav test.wav sudo strace -f -o /tmp/hal.strace -s 1024 -v /usr/sbin/hald --verbose=yes --daemon=no then wait a bit until the flood settles, check that sound recording fails again, and capture that trace: strace -f -o /tmp/arecord-fails.strace -s 1024 -v / /usr/bin/arecord -D hw:1,0 -d 3 -f cd -t wav test.wav As I said, I have no idea what hal does with the sound device, I hope that the straces can shed some light on this.
