www/chromium sndio input not implemented

[Michal Zielonka]

Hi
I had a problem with missing implementation for recording audio for sndiod
enabled in chromium port. The alsa option often had made for me problem
with lost audio input. I've checked if there is a proposal for filling
implementation for sndio input, but unfortunately I couldn't find it.
So I tried to make it myself, and the patch with working for me version I
attached in this email.
Please inform me if there are some errors or I post this mail in wrong
place.

best regards
Michał Zielonka
