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
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
It's probably something basic, but I'm not sure... how do I change
period sizes?

I don't know what can affect the prebuf value, but hopefully, something
can be figured out. And the log above was using 1.16; I tried 1.17.2

"If your card 2 only support stereo, it is strange that surround21 can
be opened"
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
has some kind of subwoofer-style audio channel is not something I'm
certain
The speaker device, "CM106 Like Sound Device," supports 7.1 surround
audio, while the "Clear Chat Comfort USB Headset" is stereo. I will
change between the two of these depending on which output I want (using
the headset when recording a screencast). I only use the M Audio fast
track as a microph
For clarification, the issue persists with both devices.
