[SoX-users] Play freeze

[Tarim <so...@me...>]

  I use sox under Lubuntu 14.04 - it's all been working fine until today
when play appears to freeze after printing the file information but
before playing any sound.

- It fails with both .wav's and .mp3's.

- top shows that play is using 99%-100% of the CPU.

- The play process doesn't respond to ctrl-C or kill; it can only be
killed with kill -9.

- mplayer and other sound outputs still work fine.

- sox inputfile outputfile still works fine.

- I recently installed pulseaudio though I'm pretty sure it's worked since
I did that so this may be a red herring.

- I tried disabling pulseaudio and/or running with export AUDIODRIVER=alsa
anyway but this didn't help.

- I tried reinstalling sox, just in case, but this didn't help either.

- I installed some extra festival voices today but I think I'm clutching
at straws now (and anyway, uninstalling them didn't help).

  Anyone got any ideas what it might be or how to investigate further?

  Cheers,
    Tarim
