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 demo (with iSpeech, SpeakIt!, Multilingual TTS Engine and US English Female TTS (by Google) installed) and for

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?
