I should mention that I was getting broken pipe errors occasionally on
the HDTV audio. With this patch I now reopen the alsa device and
everything continues on with only a minor audio glitch. Previously the
audio would just stop playing and I would see video, but hear no audio.
If we immediately get another error just return as before.

Basically seeing these messages:
audio waiting for buffer to fill: have 4096 want 4096
