USB Microphone Works with Audacity but not on the Web

[Mattthumper]

Hi,

I recently got my USB microphone working with Audacity under:
Debian 3.16.7-ckt20-1+deb8u1 (2015-12-14) i686 GNU/Linux

What I'd like to do is use that same microphone at the following Google/Chrome link in order to convert speech to text (mostly for the purposes of automating my note-taking process.):
https://www.google.com/intl/en/chrome/demos/speech.html

But the the microphone is never recognized, so nothing happens.
(And, BTW, the same microphone works fine on that same link/site when I'm using my Windoze box instead of the Linux machine.)

Here's further information:
My mic (from lsusb) - Bus 005 Device 003: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller

Audacity Devices - Host: ALSA; Playback Device: default; Recording: USB PnP Sound Device: Audio (hw:1,0): Mic:0; Channels: 1 (Mono)

Audacity Recording - Overdub (checked); Latency: Audio to buffer: 100; Latency correction: -130; Sound Activation Recording (checked); Sound Activation Level -50

Audacity Quality - Default Sample Rate: 44100 Hz; Real-time Conversion Default Sample Format: 32-bit float; Sample Rate Converter: Medium Quality; Dither: None;
High-quality Conversion Sample Rate Converter: Best Quality (Slowest) Dither: Shaped


How do I get the microphone to be recognized by my Google-Chrome browser?
TIA, Matt
