Crash in `anonymous namespace''::setup
_wasapi _stream _one _side<T>
This bug was filed from the Socorro interface and is report bp-41788e6c-70f2-44b4-a37f-7b90b2170416. ============================================================= Seen while looking at crash stats - http://bit.ly/2pIKEBf. All crashes are Windows 10. One crash showing up in 53 as well. Maybe from one of the cubeb updates?
Chun-Min, this is in you multi-channel wasapi implementation. This is crashing in a (seemingly?) perfectly valid scenario: a multi-channel input device. We're adding (at least) stereo input in bug 971528, fwiw. Do you have cycles to work on this, or should I take it ?
(also, there is a crash in windows 7, now).
Feel free to take it, or I could do it tomorrow.
Tomorrow is good, thanks.
The easiest way is to remove the assert  and let Windows to find a closest format for us(we could set layout to stereo to a N-track recording device, where N > 2). However, I need a multi-track recording device to reproduce and observe what's the behavior if I do the above modification.  https://searchfox.org/mozilla-central/rev/214345204f1e7d97abb571b7992b6deedb5ff98f/media/libcubeb/src/cubeb_wasapi.cpp#1522  https://searchfox.org/mozilla-central/rev/214345204f1e7d97abb571b7992b6deedb5ff98f/media/libcubeb/src/cubeb_wasapi.cpp#1424
Maybe use one of those virtual sound cards, or buy one and expense it. I don't trust the thing where windows finds a suitable configuration for you. It sounds nice, but I've always had issues with it in real life. I think it's best to use the mix format that is guaranteed to work, and down/up mix manually if needed.
It's better to get a sound card to test how multi-track recording works for Windows and other backends we support.
