[alsa-devel] Writing /usr/share/alsa/cards/ files

[Paul Pawlowski]

Hello,
I am writing a driver for a device with the following PCM outputs:
- Speaker
- Codec Output (Headphone/Jack)
There's also Loopback, but right now I'm unsure how does it work, I
don't think it's something I should be concerned with right now. There
are also two audio inputs (an internal Microphone as well as Codec
Input).

Thank you,
Paul Pawlowski
