squeezelite 1.4:

While playing back a DSF file, the music suddenly stopped. Squeezelite
is eating 100% CPU. Adding a strace does not reaveal much:

[fedora@wandboard ~]$ sudo strace -p 331
Process 331 attached
futex(0x2a6f4, FUTEX_LOCK_PI_PRIVATE, 1

squeezelite logs shows XRUNs:
[14:33:47.722196] output_thread:464 open output device: hw:CARD=SA14S1

Trying to restart squeezelite results in:
[14:47:55.973600] test_open:123 playback open error: Connection refused
[14:47:55.974002] output_init_alsa:640 unable to open output device

I had to restart the DAC to get things going again.
