Attempting to use a microphone in a Source game (e.g. Counter-Strike: Global Offensive) or in Steam (e.g. voice chat) crashes Steam when a Pulseaudio input device is selected.

Here's a gist with my system information: https://gist.github.com/z33ky/0435072225813cff9179
Take special note where it says "Microphone: Not set", although a microphone is plugged in; I should note that selecting an ALSA device works, although the information doesn't change.
Here's the console output when it crashed:

I'm using Pulseaudio 5.0. Sound output seems to work fine. Other applications, e.g. Mumble, can use the mic through Pulseaudio.

This is still an issue. Is there any additional info you need, or are there other ways I can help?

Here's a fresh dump btw

I tracked down the issue to a conflict with the Pulseaudio communication between the 32-bit chroot and the 64-bit host. My current workaround is using Pulse's TCP networking instead of shm or whatever is used by default, but this is certainly not an issue with Steam, so this issue can probably be closed.
