Troubles while trying the "live from microphone" typescript sample

[gabrielvv]

Hi, I tried the "live from microphone" typescript sample on Ubuntu and I had to tweak the code a bit to make it work because the default device "plughw:1,0" written in the mic library is not recognized in my case. The code ran until the 30secs delay was reached and did not log the error from arecord / mic telling that the device could not be found.

If you could allow to set a custom value for the "device" option that would be nice.

Otherwise it's awesome when it works !
