Thank you for reporting this bug to Ubuntu.
Ubuntu 15.10 (wily) reached end-of-life on July 28, 2016.
See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
We appreciate that this bug may be old and you might not be interested
in discussing it any more. But
Nope. Apparently, the issue is with either with PulseAudio or SDL... or
possibly both. SDL 1.2 does the locking thing when using timer-driven
scheduling, while SDL 2.0 does it when using interrupt-driven
scheduling. I've already submitted a ticket for SDL, so this should
probably focus on the Pu
Scratch that; an unrelated issue was resolved, but not this one.
Programs making use of OpenAL are still not making any sound, and still
freezing upon close.

Looks like it is a PulseAudio issue; the problem was resolved when I
reverted PulseAudio to interrupt-driven scheduling (tsched=0). Since
this isn't the default state of Pulseaudio on new systems, however, this
is more likely a workaround than a solution.
Whether the problem is that a new schedul
Not an OpenAL-Soft issue, but a Pulseaudio one.

OpenAL
Was there something else I needed to clarify? According to the
developer of OpenAL (from what I understand), the PulseAudio stream
keeps its existing buffer, even though OpenAL sets it to 0 for manual
starting control. I was just wondering what might have been causing
this.

Okay, looks like that fixed. the problem. Thanks for your help!
Just out of curiosity, what was happening that was causing that problem
in the first place? Was it adding 24ms fragments to the buffer to reach
a multiple of 10? And why did 44100 HMz need 10ms multiples? What
would it need to be

Maybe, maybe not; the assertion that the device is stereo is based on
the fact that it's a headset and has two obvious speakers. Whether it
