No access to microphone or speakers in chromium browser on Jetson TK1 board.

If I go to youtube in chromium browser (installed using sudo apt-get install chromium-browser): video is playing, but there is no sound.

I have similar problem with speech to text and text to speech functionality for http://codepen.io/matt-west/pen/wGzuJ demo (with iSpeech, SpeakIt!, Multilingual TTS Engine and US English Female TTS (by Google) installed) and for https://www.google.com/intl/en/chrome/demos/speech.html.

In Chromium media settings there is no microphone or speakers.

Able to play and record audio via aplay and arecord commands.

Will be grateful for any ideas?
