Description From cendio 2008-07-01 14:26:28
Windows Vista has the nice new feature of sound cards being removed whenever it
detects that speaker or microphone isn't connected. That means that Pulseaudio
will fail to open the sound card, and the user will have no sound even if the
speakers are plugged back in.

I'm not sure what they were smoking when they came up with this, or how to
solve it. We might have to keep polling the connection in case something shows
up. The newer suspend features of pulseaudio might help a bit.

Unplugging the speakers or microphone during an active session also kills the
sound until you log in again.

Same problem with Windows 7.

Another fun behaviour because of this is that you get no sound unless you have
both speakers and a microphone plugged in. Just speakers is insufficient.

Same problem with Windows 8.

Note that the problem got mitigated in bug 3222 where we load the waveout
module twice, once for playback and once for recording. This avoids the issue
of not having a microphone plugged in. We still cannot handle hotplug properly
though.
