While searching for an embedded solution with a pcie interface I came across the MC8790V.
My current doubts, since I seem unable to find this information, are regarding the voice support.
I’ve read on a pdf that all sierra voice supported modems have analog and digital audio support.
My target OS(Operating System) is linux based.
Regarding the analog audio, how is this delivered, some pins on the pcie card which will allow for a microphone and a speaker to be connected? Secondary audio card at the OS level through the drivers?
Regarding the digital audio, how is this delivered to the OS? Do I need to read/write to a /dev/ttyUSB* descriptor? Secondary audio card at the OS level through the drivers?
Thanks in advance,
