thats because there are multiple ways to do it. >I have not, as of yet, been able to find a clear description of the core >concepts around writing and reading to the device. Also some recommend >one way, and then another HOWTO says not to do it that way.. it's all >rather confusing. if you want something that's not confusing, then JACK is your friend. it was specifically designed to cut away all the complexity and force you to write a well-designed application (and yes, its me who gets to define what well-designed means :) and no, you don't need to modify anything about your stock RH system to use JACK. the modifications are only needed if you want low latency, and such modifications would be needed to get this with just ALSA anyway. a jack client will run just as well as a native ALSA (better in some senses) when the jack server is run with equivalent parameters for the audio hardware. >For instance, I'm really not sure what size my buffer needs to be, if >there is a difference between the "hardware buffer" and the buffer in my >program, How "periods" work into all this, what's the difference between >hw and plughw, etc. Also each of the examples seems to configure the >hardware differently, which I find also odd.. there are many ways of doing this too. >So to sum it up, the problem is not only that I'm new to ALSA, but that >I'm new to sound programming in general.
