[alsa-devel] Writing /usr/share/alsa/cards/ files
Hello, Is there any documentation on writing /usr/share/alsa/cards/ files? I painfully tried to create one in order to enable 2 separate audio outputs, but I ultimately failed to due to the lack of any sort of error reporting. Is there a way to enable any error reporting when parsing these files? It seems that the error output when parsing any hooks goes to nowhere.
Also, is this the correct mailing list to get help regarding alsa driver development and configuration?
Thank you, Paul Pawlowski

No documentation, unfortunately.

What kind of "2 separate audio outputs" do you need to create?

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
