This makes paz00 (aka Toshiba ac100, a popular arm-based netbook) use dmix/dsnoop by default since it doesn't support hw mixing.
This patch appears to match on card name being "tegra-alc5632", but the device tree code that just got checked in will name the card "Compal PAZ00" I believe. (and I believe this driver only supports DT not board files) Am I missing something?
Stephen, Mark, I want to raise our old question: "How do we need to call this card ? Do we need to call it tegra-alc5632, as was in pre-DT era ? Or do we need to call it "Compal PAZ00" as we introduced in DT patches ?".
The both names are applicable because "Compal PAZ00" is the name of notebook (hardware board) and tegra-alc5632 is the name of chips were used.
Since alsa-lib config file describes how to best deal with the combination of chips rather than a particular notebook name (especially given same device can have different names from different vendors and at the same time some vendors are ill-minded enough to call different devices with the same name) it would seem more logical to stick to the chips' names.
Mark, do you have some idea how to solve the issue at hand (having dmix on this netbook by default) better? Is quantity of maximum simultaneous playback/record PCM streams already queryable by the userspace? Somehow it happened that adding per-device config file was ok during all these years, is there a better way now?
