Hmm. For something that depends on a metric shitload of middle layers, it is surprisingly large...
I have to admit I don't understand the current sound situation at all. With this driver, we now have: * An OSS driver for the AP7000 Audio Bitstream DAC * A "regular" ALSA driver for the AC97C (not based on ASoC) * Two different "generic" AC97 layers: one in sound/pci/ac97 and one in sound/soc/ac97 (the AC97C driver uses the former) * An i2s driver for the AT73C213 chip using the SSC controller and SPI * Another SSC driver based on the ASoC layer * Some sort of "AT32 PCM" layer which apparently can only be used with the SSC controller * The above two being essentially identical to similar drivers for AT91
Can someone please help me out here? In particular, what is ASoC and why should I want to use it?
