Before I get to the point (see next paragraph) I want to say some words about ALSA documentation: I can't say more than: I'm confused and frustrated. That's incidentally the best description of the current documentation. I've looked into the archives, and it was the same state about 2 or 3 years before. I need ALSA, so i need to know ALSA, what it can do, what it can't do, and how to get it doing what I want. For now I can't see through all the fog of incomplete, not helpful or not existent documentation at all. I've dug through the wiki and came to AlsaComplaint page [0]. I've come to the result that I want to understand ALSA and want to share my knowledge. I want to write the famous but nevertheless not yet existing "Everything You Could Ever Need to Know About ALSA"-document. I need some help for this. I think I'm quite qualified for this task as I don't know much about ALSA, so I can ask the right questions. But I need people answering my questions. Let's get into it: What is this thing about the device? First the most important question: I know for now that in a standard configuration "hw:0,0" is quite fine. For the second card "hw:1,0" is hopefully working. What exactly does that mean? Sometimes I see "plughw:0,0". What's the difference to "hw:0,0"? How can I find out which device strings are valid (except for guessing?) Next: How can I find out which device is the device my speakers are connected to? More will follow...
