On my laptop, I've got an .asoundrc file that outputs sound to my USB headset. This works fine for SMplayer and Firefox. However, Google Chrome (at least, Flash-based and HTML5-based videos and HTML5-based audio in Chrome) plays through the laptop speakers instead. I've tried running Chrome from a command-line, hoping there would be some helpful output, but no such luck. I've tried looking through Google for whether Chrome even uses ALSA, or if it uses something else, but I have been unsuccessful in this.
This question seems to be the same issue, but no suggestion was made.
Anyone have any ideas? I'm running Gentoo with a 3.10.17 kernel, 1.0.27 ALSA utils, 2.6.5 FVWM, and 36.0.1985.143 Chrome. If you need more info, please let me know.
EDIT:
I've configured the USB headset as the default ALSA device. Volume levels for both headset and onboard are set and un-muted using alsamixer. My .asoundrc file is as follows.
ctl.!default {
type hw
card Headset
}
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm {
type hw
card Headset
}
period_size 1024
buffer_size 4096
}
bindings {
0 0
1 1
}
}
pcm.!default {
type plug
slave.pcm dmixer
}
EDIT 2: More info
Ran both mplayer and google-chrome-stable from command-line. Once mplayer was playing a video (and audio), I started Chrome, went to YouTube, and played a video. The audio came out the speakers. Command-line output was as follows:

alsamixer
and hitting "F6" to select the soundcard while Chrome is playing? Might give you a bit of useful feedback. And just for your sanity, yes, Chrome works with ALSA (most things work with ALSA...outside of particularly old OSS-only applications, for which there are workarounds usually, and a few new ones that insist on pulseaudio on top of ALSA).
