I'm also affected by this bug. I noticed it with mplayer in Ubuntu
10.04:
$ strace mplayer test.mp3
...
futex(0x23f68f0, FUTEX_UNLOCK_PI_PRIVATE, 0) = 0
futex(0x240c0d4, FUTEX_WAIT_REQUEUE_PI_PRIVATE, 5, NULL, 0x23f68f0) = -1 EAGAIN
(Resource temporarily unavailable)
futex(0x240c0d4,
Considering that mplayer is also affected, it does not seem to be a bug in sox.
It may be a bug in pulseaudio, because the mplayer command line option -ao
oss fixes the problem for me (though it causes other problems related to oss
access).
Is it possible to move bug reports to another project,
Disabling pulseaudio by following the instructions on
https://wiki.ubuntu.com/PulseAudio/Log also temporarily fixes the
problem for me.

You received this bug notification because you are a member of Ubuntu
Bugs,
I can confirm this bug. It still affects me exactly as you described
with 2.6.27.1.
Your workaround worked for me, after I compiled 2.6.27.1 with
CONFIG_MAC80211_DEBUGFS turned off the lockups went away. My hardware is
an iwl3945-based Lenovo T60p.
