I was running some exploration about how to access a microphone’s input from a Balena container running in a NUC device.
Initially, I tried to use the NUC’s built-in mic, but without success. I moved on to try with an external jack mic but with the same result.
I am using the browser block and I am loading this URL. It is basically a website that tests a mic.
I accessed the website and allows for the mic’s usage but no sound is captured. I check all browser settings without success.
I try other similar websites always with the same result.
Inspired by this thread I follow the instructions to make sure the browser permission and settings are OK.
The first red flag is: The list of available mic devices presents shows a lot of intel stuff but nothings about the external mic.
By SSH in the browser module and running
amixer controls i get some entries but I really do not know how relevant they are.
numid=8,iface=CARD,name='Front Headphone Jack' numid=4,iface=MIXER,name='Capture Volume' numid=6,iface=MIXER,name='Mic Boost Volume' numid=47,iface=MIXER,name='Digital Capture Volume' numid=7,iface=CARD,name='Mic Phantom Jack'
I tried to change some values as suggested in the same thread but still do not able to capture audio on the mic.
So someone any digestion how can I try next?
Thanks a lot,
